ARM: shmobile: Move shmobile_scu_base from .text to .bss
shmobile_scu_base is being written to, so it doesn't belong in the .text
section. Fix this by moving it from asm .text to C .bss, as it's no
longer used from asm code since commit

ARM: SoC support for Tegra platforms for v4.5
Here's a single-SoC topic branch that we've staged separately. Mainly because it was hard to sort the branch contents in a way that fit our existing branches due to some refactorings. The code has been in -next for quite a while, but we staged it in arm-soc a bit late, which is why we've kept it separate from the other updates and are sending it separately here. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWoqsGAAoJEIwa5zzehBx3/F4QAJo4FEU+KTOhUggDV+KPn9ZD Re1SAKTpKo9elMdDdTZZObHYPf+RXqun50C4pQiSVfyDm9syZaxtWjjZvshwsATq 178fNN+0C/7aenj8Zpq/NrLwBl1N51cSdc1ii3TcN/OA5XDgpmGJTdqMziDiXAkd Nt847qSEhIvAfOtcZR2drk2wBKGCTA/NpGU3HCryPAlO7RnAbJY4Ywj0bU01Lc9y bSJYh1SPaa1PdDCBJjtbk6L8iGl39K5oy0e6ehECEviLBVtWIL0zqh101XGbPVtv vtpVJ40NciiHknCBEiJkYiY9b7BNZYMeuwLarqk7TxyW4Vm5Rl5CFkEot0X/b70J XSxca6KGLzSgmCYDzJtLgtmyBUDoGqNwiPnNVIjrGIt9uOlWeHGb7TUKjBZaJr7G nXiKKU17zhb28hEo8JjIGcuFcOGlwlBhoOKhOYePiXX/iA03M8SEZg3XXyYMiaVz j9PcfOQptc7CyCAyiUQW36cZc1vQlnNxpiZstF0QsJ+Poe1kPlJIVpOarrfFdvh5 wJrS4L5YoIzb5robsNLNJ6XXiRnqvxgO6dEdA3RoI1bMaFsXVRCb03EoxVYqS4RF o+4h0KYQ8gPmAhA/ii/IDHps51TCCDOolAyWLfmYlqXu76IjOlC1LTYxi8RAGZNL xExyC0A3YDfONv6mx07R =LG3u -----END PGP SIGNATURE----- Merge tag 'armsoc-tegra' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC support for Tegra platforms from Olof Johansson: "Here's a single-SoC topic branch that we've staged separately.

tree wide: use kvfree() than conditional kfree()/vfree()
There are many locations that do if (memory_was_allocated_by_vmalloc) vfree(ptr); else kfree(ptr); but kvfree() can handle both kmalloc()ed memory and vmalloc()ed memory using is_vmalloc_addr(). Unless callers have special reasons, we can replace this branch with kvfree(). Please check and reply if you found problems.

More power management and ACPI updates for v4.5-rc1
- Modify the driver core and the USB subsystem to allow USB devices to stay suspended over system suspend/resume cycles if they have been runtime-suspended already beforehand and fix some bugs on top of these changes (Tomeu Vizoso, Rafael Wysocki). - Update ACPICA to upstream revision 20160108, including updates of the ACPICA's copyright notices, a code fixup resulting from a regression fix that was necessary in the upstream code only (the regression fixed by it has never been present in Linux) and a compiler warning fix (Bob Moore, Lv Zheng). - Fix a recent regression in the cpuidle menu governor that broke it on practically all architectures other than x86 and make a couple of optimizations on top of that fix (Rafael Wysocki). - Clean up the selection of cpuidle governors depending on whether or not the kernel is configured for tickless systems (Jean Delvare). - Revert a recent commit that introduced a regression in the ACPI backlight driver, address the problem it attempted to fix in a different way and revert one more cosmetic change depending on the problematic commit (Hans de Goede). - Add two more ACPI backlight quirks (Hans de Goede). - Fix a few minor problems in the core devfreq code, clean it up a bit and update the MAINTAINERS information related to it (Chanwoo Choi, MyungJoo Ham). - Improve an error message in the ACPI fan driver (Andy Lutomirski). - Fix a recent build regression in the cpupower tool (Shreyas Prabhu). / -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJWoCQ4AAoJEILEb/54YlRxLscQALEFVKSRnNaco72OqqRZs9Bu 1RI6TgHTpZxR+Ef0+QWqE1QMnDwfImGhKDbSRm/t3S2sMYYZbAOL8cu4y6GmkBv4 bOon/f9WEoPlQCFoo/6U4u8H45rNT5W9zX5+Bva8x+4Wu3n2J1QdvirnS5JHeHe1 o6tGLaHuZXSwX8SLnCk8gJYK1VhATxbubJtpcVtvlnAhO11qUAwsscCrkUmB60i7 5hLyrZb06hoa/hZVcIefGFuSd9qPhzDMQE2M20EohQ7UVkNJQdY9QNHMqCk2P42T nMWCNSwGnwfiO1p9ByXqunOFBCmyL7P+KV/DHsz6TFCVjz+jeG53Kqey9SkSJ/2W iaAE80K9MfOMvg8j7rib6fTn5uXBwRfqdeUDF/Hr64QqJoRn3R2LX4HmZe4L8ufb zA1rece67o8FD+7p7GkNbT3rPV/kA62tn/moFk446X5N+b261Kz90t1DVci8kRVf k+1gcvEdqO0GPpEHoirfXrBvQFixqkXakKj4r2aAob/DldQeLX7CkOUuRRJ1ykec bxwI9R0v8MlVe5rDxg+rPB0I9EFxRDmxqxpU5j0MRWxKnMRzLvBtHuk8YNVS/eU1 xwyJOGcwF6yI0PaCFggPqmhebSrWLE7wJxaK+3bC+yiDTvHYPjB+4MfQrmkRAwwM azgb+ZgXDYx5wXeb8EjB =bKJ9 -----END PGP SIGNATURE----- Merge tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull more power management and ACPI updates from Rafael Wysocki: "This includes fixes on top of the previous batch of PM+ACPI updates and some new material as well. From the new material perspective the most significant are the driver core changes that should allow USB devices to stay suspended over system suspend/resume cycles if they have been runtime-suspended already beforehand. Apart from that, ACPICA is updated to upstream revision 20160108 (cosmetic mostly, but including one fixup on top of the previous ACPICA update) and there are some devfreq updates the didn't make it before (due to timing). A few recent regressions are fixed, most importantly in the cpuidle menu governor and in the ACPI backlight driver and some x86 platform drivers depending on it.

Specifics: - Modify the driver core and the USB subsystem to allow USB devices to stay suspended over system suspend/resume cycles if they have been runtime-suspended already beforehand and fix some bugs on top of these changes (Tomeu Vizoso, Rafael Wysocki). - Update ACPICA to upstream revision 20160108, including updates of the ACPICA's copyright notices, a code fixup resulting from a regression fix that was necessary in the upstream code only (the regression fixed by it has never been present in Linux) and a compiler warning fix (Bob Moore, Lv Zheng). - Fix a recent regression in the cpuidle menu governor that broke it on practically all architectures other than x86 and make a couple of optimizations on top of that fix (Rafael Wysocki). - Clean up the selection of cpuidle governors depending on whether or not the kernel is configured for tickless systems (Jean Delvare). - Revert a recent commit that introduced a regression in the ACPI backlight driver, address the problem it attempted to fix in a different way and revert one more cosmetic change depending on the problematic commit (Hans de Goede). - Add two more ACPI backlight quirks (Hans de Goede). - Fix a few minor problems in the core devfreq code, clean it up a bit and update the MAINTAINERS information related to it (Chanwoo Choi, MyungJoo Ham). - Improve an error message in the ACPI fan driver (Andy Lutomirski). - Fix a recent build regression in the cpupower tool (Shreyas Prabhu)" * tag 'pm+acpi-4.5-rc1-2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: (32 commits) cpuidle: menu: Avoid pointless checks in menu_select() sched / idle: Drop default_idle_call() fallback from call_cpuidle() cpupower: Fix build error in cpufreq-info cpuidle: Don't enable all governors by default cpuidle: Default to ladder governor on ticking systems time: nohz: Expose tick_nohz_enabled ACPICA: Update version to 20160108 ACPICA: Silence a -Wbad-function-cast warning when acpi_uintptr_t is 'uintptr_t' ACPICA: Additional 2016 copyright changes ACPICA: Reduce regression fix divergence from upstream ACPICA ACPI / video: Add disable_backlight_sysfs_if quirk for the Toshiba Satellite R830 ACPI / video: Revert "thinkpad_acpi: Use acpi_video_handles_brightness_key_presses()" ACPI / video: Document acpi_video_handles_brightness_key_presses() a bit ACPI / video: Fix using an uninitialized mutex / list_head in acpi_video_handles_brightness_key_presses() ACPI / video: Revert "ACPI / video: driver must be registered before checking for keypresses" ACPI / fan: Improve acpi_device_update_power error message ACPI / video: Add disable_backlight_sysfs_if quirk for the Toshiba Portege R700 cpuidle: menu: Fix menu_select() for CPUIDLE_DRIVER_STATE_START == 0 MAINTAINERS: Add devfreq-event entry MAINTAINERS: Add missing git repository and directory for devfreq ... |

ARM: SoC defconfig updates for v4.5
As usual, a bunch of commits, mostly adding drivers and other options to defconfigs because it makes sense to have them enabled on various development or product boards. Too much to enumerate each here. There's an introduction of a pxa_defconfig, since PXA finally will allow building a shared kernel for all boards. With this, we can hopefully remove a bunch of individual defconfigs down the road but it requires a bit of real life testing and transition period. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWnsEkAAoJEIwa5zzehBx33lcQAItHXIplC5tC3EjnJLY2lW8j bZ38mWVU0I5jT688hlCw7eOCajO30sG0RM4vqlG1PpvL6mbiM3kX6s0LBUVQa6J0 bCHLkzVkXBXO3VJFAHcY821XdBpnINgmAt/AEElSDrBK2wi/kb6dvP0ClYe/4zhB B44P/pWtYpn09KyGkPdIanSGPG0ikvP03i0mKRxlFwyB2RSJiFzsVlNtUYQMgDMp SOsN3fO2AzZCWCNF+gz7/ekWzo7hGlXNU3WeIIWIs3GL6FTi9p//LeP7w9oTxGbv d6hId6TGp7rYCA0XjwJtRK1kkQGVLxCltR/UDBSCjc4sS4Xh8ME35TDWo1Z/yHKr UtlKI2VHMSkxkk1DChbUYS8ojBOmgVApvG4BTYm0DICvW7zeGJqtOD/zM5CgKJWA AfVAL2c9N47YyOYcehDucig+yuxf4+RV92hEO+K84MWL1MYi5o/J3BJqmQ7dtfBT MYLLgcpzsUPC9R43mUs69/zojBFCPPPIz6CBn29m9+BAkX887jvInln7fKK0TaG8 V9Y0eHmgEHvshomYrJwkFKSIq7NhU0M+ZCGvBNP5a1wDNEw/Kc0/Sz1QVHrbN+P1 t9jZZKoq8s2WvEtVpghjbQAxCf/tUFx5zSfWf4MbuduaTtM119EkaSoROWvjIaId Aj57uYO8cm7/bGNEMQ3k =YsCa -----END PGP SIGNATURE----- Merge tag 'armsoc-defconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC defconfig updates from Olof Johansson: "As usual, a bunch of commits, mostly adding drivers and other options to defconfigs because it makes sense to have them enabled on various development or product boards.

ARM: SoC multiplatform code changes for v4.5
This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel. It has been a tremendous amount of cleanup and refactoring by a huge number of people, and creation of several new (and major) subsystems to better abstract out all the platform details in an appropriate manner. The bulk of this branch is a large patchset from Arnd that brings several of the more minor and older platforms we have closer to multiplatform support. Among these are MMP, S3C64xx, Orion5x, mv78xx0 and realview Much of this is moving around header files from old mach directories, but there are also some cleanup patches of debug_ll (lowlevel debug per-platform options) and other parts. Linus Walleij also has some patchs to clean up the older ARM Realview platforms by finally introducing DT support, and Rob Herring has some for ARM Versatile which is now DT-only. Both of these platforms are now multiplatform. Finally, a couple of patches from Russell for Dove PMU, and a fix from Valentin Rothberg for Exynos ADC, which were rebased on top of the series to avoid conflicts. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIUAwUAVqAGcmCrR//JCVInAQLDog/4x9F0PHGmZhexGfFOpi2Od63Jjx55izRU zRXqRjjFjambOrZuOx8lEGDy/qzqKbsDU8D1P4IUugkDr2bLSXv+NTLZL1kNBIdm YOlJhw/BmzLYqauOHmBzGhtv1FDUk3rqbgTsP5tTWj5LpSkwjmqui3HBZpi+f3Rr YOn+NeQSARiw+51D0b106a9RFshQXRGgn5m3xFjLWhJqshb2z2Ew5cogX/zdwrrM ss1BFomxsvgk6S+snN6v7cEX2iXe3r89qNR5jEW5BgNpQGFsAUeXPr9zzH07L/Qq O7XLw9jt5MX/X5372zVHPb57WoflLbF9cFaaDUZV3eTqt3lC67BTxOtYIdC2i90k E5GYlsy88CRwT2EO+ok/6UTryph+hVv7JqHfbKfnISrbraMCK36DtDTpBIpZ9uYF rRB7ncJZUWBcyoe+qvitSl+2KV54iB1ez2RXsketxM98dDZsfB2M2ImFou1F/Pgg ALvpifPubi/uDe7xNUsSuaT6/3jAomBuNsxnkYJ3NeiH/+duZbOYGkzK/LlcjZyc UrA0IpLfwIFsBNzwfpZPZ1lkEu8Y1YZZ+Hv9k65q1wMuBDgrFI5zUeYrPZi4pN9T Yo1xP9FstVLDouJrpGZo12VIIxR1UBeGqfRI/BZ58LEF3PRq/g2OVFsdQia5gZKr ddiJKSL1Vw== =z1AW -----END PGP SIGNATURE----- Merge tag 'armsoc-multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC multiplatform code updates from Arnd Bergmann: "This branch is the culmination of 5 years of effort to bring the ARMv6 and ARMv7 platforms together such that they can all be enabled and boot the same kernel.

This also adds stricter type checking for callers of do_div, which has uncovered a number of bugs in existing code, and fixes up the ones we have found. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIVAwUAVqARKWCrR//JCVInAQJrBhAAlwZL0IiVGFfDXWtvQGOm+yC5j4vdIhMf 1scsvRbk3ln1xUk5+NM61NpxbQotro78K5HxFZFhaVGUTbbFXM9w2VZSyI8ZaGAJ Od6lBUUyLQmzlbHDJ3v/zrZn8Up7qZlRApmXcbUVDtssfnEfKk4xA2RG9JwIMS1c uZMvnD7N3P9vxDPl+CsYlB2osi6Yks3VQ1tXYe2z6siO+H67zHaF08+ls7fbsd3d oyKjZqlaQ02MIOr+AdR0h9iKyJJ6SXT0DQlsMyzB6aBWmeBCNLNALNIiukDk9Qc1 VV3sF1MOS3LtfU2TeOx4Na7hcd2iC6WYLb271iApO2Ww7t16n+de3i6AipZxLUJ0 08jiRlisTzUhXDobRSqI3mcQlxrB5UGfyblab2z/MqGGmIGJSPPRdTPRQUgi0ZKg jksSmsaPwOQp64FhTgECLJthlYX7h6ULjkvJ9h60gZHa4jhGZbGPeMwHPf1uSm95 EvQE971Ssgm4jwhvxZ/kt1ruuZI/fxxG1Qfw+C25QkXZGKye2nB+icLWeMwz+FXG HLqkmaAjasf5MAV1GiK8U6zoC6bCOLU0Lea83hOwRPZ999v3Nym1giSatNv4/pB+ QmkXRvFi93cdQ643l7xcUEDT2zpk4pogF3xREiBhyaXtqLlT7pPMKsBQOgdWvFuu Ou0ZbEAwIVo= =4psa -----END PGP SIGNATURE----- Merge tag 'asm-generic-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pull asm-generic updates from Arnd Bergmann: "The asm-generic tree this time contains one series from Nicolas Pitre that makes the optimized do_div() implementation from the ARM architecture available to all architectures.

ARM: debug-ll: fix BCM63xx entry for multiplatform
During my randconfig build testing, I found that a kernel with
DEBUG_AT91_UART and ARCH_BCM_63XX fails to build:
arch/arm/include/debug/at91.S:18:0: error: "CONFIG_DEBUG_UART_VIRT" redefined [-Werror]
It turns out that the DEBUG_UART_BCM63XX option is enabled whenever
the ARCH_BCM_63XX is, and that breaks multiplatform kernels because
we then end up using the UART address from BCM63XX rather than the
one we actually configured (if any).
This changes the BCM63XX options to only have one Kconfig option,
and only enable that if the user explicitly turns it on.

ARM: dts: armadillo800eva Correct extal1 frequency to 24 MHz
On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported
by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from
25 MHz to 24 MHz to fix this.
This matches the Armadillo-800 EVA Product Manual, which claims the main
crystal runs at 24 MHz, and the old legacy/reference board code.

GPIO bulk updates for the v4.5 kernel cycle:
Infrastructural changes: - In struct gpio_chip, rename the .dev node to .parent to better reflect the fact that this is not the GPIO struct device abstraction. We will add that soon so this would be totallt confusing. - It was noted that the driver .get_value() callbacks was sometimes reporting negative -ERR values to the gpiolib core, expecting them to be propagated to consumer gpiod_get_value() and gpio_get_value() calls. This was not happening, so as there was a mess of drivers returning negative errors and some returning "anything else than zero" to indicate that a line was active. As some would have bit 31 set to indicate "line active" it clashed with negative error codes. This is fixed by the largeish series clamping values in all drivers with !!value to [0,1] and then augmenting the code to propagate error codes to consumers. (Includes some ACKed patches in other subsystems.) - Add a void *data pointer to struct gpio_chip. The container_of() design pattern is indeed very nice, but we want to reform the struct gpio_chip to be a non-volative, stateless business, and keep states internal to the gpiolib to be able to hold on to the state when adding a proper userspace ABI (character device) further down the road. To achieve this, drivers need a handle at the internal state that is not dependent on their struct gpio_chip() so we add gpiochip_add_data() and gpiochip_get_data() following the pattern of many other subsystems. All the "use gpiochip data pointer" patches transforms drivers to this scheme. - The Generic GPIO chip header has been merged into the general <linux/gpio/driver.h> header, and the custom header for that removed. Instead of having a separate mm_gpio_chip struct for these generic drivers, merge that into struct gpio_chip, simplifying the code and removing the need for separate and confusing includes. Misc improvements: - Stabilize the way GPIOs are looked up from the ACPI legacy specification. - Incremental driver features for PXA, PCA953X, Lantiq (patches from the OpenWRT community), RCAR, Zynq, PL061, 104-idi-48 New drivers: - Add a GPIO chip to the ALSA SoC AC97 driver. - Add a new Broadcom NSP SoC driver (this lands in the pinctrl dir, but the branch is merged here too to account for infrastructural changes). - The sx150x driver now supports the sx1502. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWmsZhAAoJEEEQszewGV1ztq0QAJ1KbNOpmf/s3INkOH4r771Z WIrNEsmwwLIAryo8gKNOM0H1zCwhRUV7hIE5jYWgD6JvjuAN6vobMlZAq21j6YpB pKgqnI5DuoND450xjb8wSwGQ5NTYp1rFXNmwCrtyTjOle6AAW+Kp2cvVWxVr77Av uJinRuuBr9GOKW/yYM1Fw/6EPjkvvhVOb+LBguRyVvq0s5Peyw7ZVeY1tjgPHJLn oSZ9dmPUjHEn91oZQbtfro3plOObcxdgJ8vo//pgEmyhMeR8XjXES+aUfErxqWOU PimrZuMMy4cxnsqWwh3Dyxo7KSWfJKfSPRwnGwc/HgbHZEoWxOZI1ezRtGKrRQtj vubxp5dUBA5z66TMsOCeJtzKVSofkvgX2Wr/Y9jKp5oy9cHdAZv9+jEHV1pr6asz Tas97MmmO77XuRI/GPDqVHx8dfa15OIz9s92+Gu64KxNzVxTo4+NdoPSNxkbCILO FKn7EmU3D0OjmN2NJ9GAURoFaj3BBUgNhaxacG9j2bieyh+euuUHRtyh2k8zXR9y 8OnY1UOrTUYF8YIq9pXZxMQRD/lqwCNHvEjtI6BqMcNx4MptfTL+FKYUkn/SgCYk QTNV6Ui+ety5D5aEpp5q0ItGsrDJ2LYSItsS+cOtMy2ieOxbQav9NWwu7eI3l5ly gwYTZjG9p9joPXLW0E3g =63rR -----END PGP SIGNATURE----- Merge tag 'gpio-v4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "Here is the bulk of GPIO changes for v4.5. Notably there are big refactorings mostly by myself, aimed at getting the gpio_chip into a shape that makes me believe I can proceed to preserve state for a proper userspace ABI (character device) that has already been proposed once, but resulted in the feedback that I need to go back and restructure stuff. So I've been restructuring stuff. On the way I ran into brokenness (return code from the get_value() callback) and had to fix it. Also, refactored generic GPIO to be simpler. Some of that is still waiting to trickle down from the subsystems all over the kernel that provide random gpio_chips, I've touched every single GPIO driver in the kernel now, oh man I didn't know I was responsible for so much... Apart from that we're churning along as usual. I took some effort to test and retest so it should merge nicely and we shook out a couple of bugs in -next.

sound updates for 4.5-rc1
We've had quite busy weeks in this cycle. Looking at ALSA core, the significant changes are a few fixes wrt timer and sequencer ioctls that have been revealed by fuzzer recently. Other than that, ASoC core got a few updates about DAI link handling, but these are rather straightforward refactoring. In drivers scene, ASoC received quite lots of new drivers in addition to bunch of updates for still ongoing Intel Skylake support and topology API. HD-audio gained a new HDMI/DP hotplug notification via component. FireWire got a pile of code refactoring/updates with SCS.1x driver integration. More highlights are shown below. [NOTE: this contains also many commits for DRM. This is due to the pull of drm stable branch into sound tree, as the base of i915 audio component work for HD-audio. The highlights below don't contain these DRM changes, as these are supposed to be pulled via drm tree in anyway sooner or later.] Core - Handful fixes to harden ALSA timer and sequencer ioctls against races reported by syzkaller fuzzer - Irq description string can be unique to each card; only for HD-audio for now ASoC - Conversion of the array of DAI links to a list for supporting dynamically adding and removing DAI links - Topology API enhancements to make everything more component based and being able to specify PCM links via topology - Some more fixes for the topology code, though it is still not final and ready for enabling in production; we really need to get to the point where that can be done - A pile of changes for Intel SkyLake drivers which hopefully deliver some useful initial functionality for systems with this chipset, though there is more work still to come - Lots of new features and cleanups for the Renesas drivers - ANC support for WM5110 - New drivers: Imagination Technologies IPs, Atmel class D speaker, Cirrus CS47L24 and WM1831, Dialog DA7128, Realtek RT5659 and RT56156, Rockchip RK3036, TI PC3168A, and AMD ACP - Rename PCM1792a driver to be generic pcm179x HD-Audio - Use audio component for i915 HDMI/DP hotplug handling - On-demand binding with i915 driver - bdl_pos_adj parameter adjustment for Baytrail controllers - Enable power_save_node for CX20722; this shouldn't lead to regression, hopefully - Kabylake HDMI/DP codec support - Quirks for Lenovo E50-80, Dell Latitude E-series, and other Dell machines - A few code refactoring FireWire - Lots of code cleanup and refactoring - Integrate the support of SCS.1x devices into snd-oxfw driver; snd-scs1x driver is obsoleted USB-audio - Fix possible NULL dereference at disconnection - A regression fix for Native Instruments devices Misc - A few code cleanups of fm801 driver -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJWmmhNAAoJEGwxgFQ9KSmk/wsP/3eO+giAT9VRPa6qxR6VdT6I dZwTxcp4ZzUrgLxk9k5VYjqey6QL+1xWfl3Abrd+NzXDj1wo4KsDh2XCKG1btO9K UpIZf76Nzt7o91pzHbsU6mrjDeoVNqloZoGbg1utAmmegaXH3owd18p/ZHfE3sz2 BbaHmYW/R8lnaBgBhzqJB97+zRaLJmMWpWHfpHaIPjdfw8/V4j76jtPnpmv2hDZl BHXVHcQXjVGunFRzxdzBLuTC+FmhzUeTAbbAdOT4fEoOCv5MtZqYppNxdhj+b9l5 mrsXe5FBTNmrt9Z5TtfCuzgJPkzoDperFb0aKd7wI1jVMtLzkNCMlanHr9U6B6fr jSrs6l25xrpF1BBfRMfHjNudA5vng/XC5dtW00JofXSrIxtwPNUoDDiqJgw7xVm5 aVWK7KkQIjRbHdCQaeTymv70oHHKei92hbCrXUobXZ7wLeJMXNVPT25ttChWrgAI 7cu5h+K5PjReI/sJFTMPL4aHZ+jAn9quQl7vK8EXiL9E6G8lLiuBiVW6hjGd9At+ Z6UyGV+nCM6O3qZcyParMuLkNtWx9uT7Pcn8oTZAdKPngNhsf8+yl9qmsFkNLDC4 LKPx0+rdCjtMKn2du3krsHhG3EN9pLDrE6g5U3d6Cz83e69Y7fCuSjl31SjD91H0 bZDcM/ejYSbid3yKN4TL =Gvgb -----END PGP SIGNATURE----- Merge tag 'sound-4.5-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "We've had quite busy weeks in this cycle.

The clk framework and driver changes for 4.5 look pretty typical. The
bulk of the changes are to clk controller drivers, though some improvements to the core and some re-usable blocks/templates also received some love. In this past cycle the clk maintainers developed a good workflow for handling the common case of patch submissions containing a new drivers, new shared Device Tree header and a new Device Tree binding description. This requires coordination with the Device Tree maintainers and with the architecture maintainers (typically the arm-soc tree in our case). This explains the increase in changes to include/dt-bindings/... and to Documentation/devicetree/bindings/clock/... coming from the clk tree. The same commits can be expected to come through those trees on occasion, through the use of shared, immutable branches. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJWmVD1AAoJEKI6nJvDJaTUWqAQAJRqH+iKSnLyuVek6USYPXdp ZOW1JHIySCUF/ci3fvv9vbIuW/w4Uc9FdRdAfIIaWO32bpk4ljtEogVasvavL/54 geN+0YERZpth+PL/wk+g+Dons/8BgN9AL+0ToaVVh2MsRE903jWpe+l0qWCl+SUn DQF+yB9F4QcVT7gb+KI0B6hr6lv5Mu/t9Ffq3DrK2UG71IEbrv953pVo19foZqbf FgMgduERMHvaM/R6p5xfXxIESbjE+QNMnykEo6bWcHF2wfQrIiYlW1khtnsigNus kze2mYWjG77KGkrOex5kwjuBDPfiaGAstk3jcRCCMB7nRmuFcJgryF8003CD3QvW +cY+ZBSkyXXtL/nrkefebAplQjsvum7dJ+W6hxA32B772jFL8s8ee5rGda0ibw8N nFQRopVcNPoR52tjmSEOxm7Z9vqoDj5qManDdZe62kr6bCFId97E6SzeGgeyDuBQ V7tkss9klHMhx29V37wkyl+A/pWXO+CsGzHLEivH8/L1CysMK1WGhyHJJ2/JTDTR n3z1EYdg67PbHpfhboscuLP+sHcrAefOCe2la4wKxwqd4DGw6J8RhhVZml6XnfQ3 I4yLri8Pguol49G1ac1U87ylebKsXhWR5CRHVas1BFHrt0FGULHnl0ZOLzOu4GRZ h8/nd9ZODLFhB1w7fL1B =nkGr -----END PGP SIGNATURE----- Merge tag 'clk-for-linus-4.5' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk framework updates from Michael Turquette: "The clk framework and driver changes for 4.5 look pretty typical.

kvm: rename pfn_t to kvm_pfn_t
To date, we have implemented two I/O usage models for persistent memory, PMEM (a persistent "ram disk") and DAX (mmap persistent memory into userspace). This series adds a third, DAX-GUP, that allows DAX mappings to be the target of direct-i/o. It allows userspace to coordinate DMA/RDMA from/to persistent memory. The implementation leverages the ZONE_DEVICE mm-zone that went into 4.3-rc1 (also discussed at kernel summit) to flag pages that are owned and dynamically mapped by a device driver. The pmem driver, after mapping a persistent memory range into the system memmap via devm_memremap_pages(), arranges for DAX to distinguish pfn-only versus page-backed pmem-pfns via flags in the new pfn_t type. The DAX code, upon seeing a PFN_DEV+PFN_MAP flagged pfn, flags the resulting pte(s) inserted into the process page tables with a new _PAGE_DEVMAP flag. Later, when get_user_pages() is walking ptes it keys off _PAGE_DEVMAP to pin the device hosting the page range active. Finally, get_page() and put_page() are modified to take references against the device driver established page mapping. Finally, this need for "struct page" for persistent memory requires memory capacity to store the memmap array. Given the memmap array for a large pool of persistent may exhaust available DRAM introduce a mechanism to allocate the memmap from persistent memory. The new "struct vmem_altmap *" parameter to devm_memremap_pages() enables arch_add_memory() to use reserved pmem capacity rather than the page allocator. This patch (of 18): The core has developed a need for a "pfn_t" type [1]. Move the existing pfn_t in KVM to kvm_pfn_t [2].

mm: differentiate page_mapped() from page_mapcount() for compound pages
Let's define page_mapped() to be true for compound pages if any sub-pages of the compound page is mapped (with PMD or PTE). On other hand page_mapcount() return mapcount for this particular small page. This will make cases like page_get_anon_vma() behave correctly once we allow huge pages to be mapped with PTE. Most users outside core-mm should use page_mapcount() instead of page_mapped(). Signed-off-by: Kirill A.

MTD updates for v4.5:
Generic MTD * populate the MTD device 'of_node' field (and get a proper 'of_node' symlink in sysfs) - This yielded some new helper functions, and changes across a variety of drivers * partitioning cleanups, to prepare for better device-tree based partitioning in the future - Eliminate a lot of boilerplate for drivers that want to use OF-based partition parsing - The DT bindings for this didn't settle yet, so most non-cleanup portions are deferred for a future release NAND * embed a struct mtd_info inside struct nand_chip - This is really long overdue; too many drivers have to do the same silly boilerplate to allocate and link up two "independent" structs, when in fact, everyone is assuming there is an exact 1:1 relationship between a NAND chips struct and its underlying MTD. This aids improved helpers and should make certain abstractions easier in the future. - Also causes a lot of churn, helped along by some automated code transformations * add more core support for detecting (and "correcting") bitflips in erased pages; requires opt-in by drivers, but at least we kill a few bad implementations and hopefully stave off future ones * pxa3xx_nand: cleanups, a few fixes, and PM improvements * new JZ4780 NAND driver SPI NOR * provide default erase function, for controllers that just want to send the SECTOR_ERASE command directly * fix some module auto-loading issues with device tree ("jedec,spi-nor") * error handling fixes * new Mediatek QSPI flash driver Other * cfi: force valid geometry Kconfig (finally!) - this one used to trip up randconfigs occasionally, since bots aren't deterred by big scary "advanced configuration" menus More? Probably. See the commit logs. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJWlZSyAAoJEFySrpd9RFgtVkEP/096SsFs+71jPgc6ARHIKt6j b8vnGeMpjYErIjRZXjeLJvD4whYcooM1IDXiy7HPFEF/DrmN+dBjF6gYNHhC9n+X bpIVS+TJknBKqcAClPVArZI77Fugzn1jBuo8t8rH5bpHNvTfucOt0VmQAu/NRxXe qUHNXDdQ+nb7qUy47Us66ygDiUh6tXYD2gp3duE8W49FnoSxcXNTq467RGyVBREl U+5mxsD4y49mktG3xatYdwmvz9UTWOYa+u4NTG282kP6GrqTPTw0ESaxfViP9nyd WSexhylV/PFJjxyMRazy1EZJ3kiQCQvza/VMmZ6fDSzwZ4JephuCDGLd3MhE3/E7 C275DNHC6U0s79gSlihrYHKEkMN8uNUDwNfeZhY05jXL56kFxUlUvvq14bt4gDDK xrPLNKLOpcoAMiRFOM5NdBeyQx9REq1G09I8MBjBN0kW254lIjGm6naCOl0L/Fu1 Y4c7hJCLFUTrki9DeNcP6dtpSCVdOap4C+920FZyrBnUzpt5G/rUGdSQu0iY5i4j BHe/Pr6ybkQ+b7XZbJlbFOy/u6TL/3T9Z4L52RK4j6F3r2EkNiH0+892L4v4qih6 Bt2wsFw8gGHC3dnnh5yfyst/QaG2Mu7V2JJjrrlERjWQJepWqYnUjlH/PgwKj7t0 /pnD40iDmUG2aYe+Jmcv =wFQI -----END PGP SIGNATURE----- Merge tag 'for-linus-20160112' of git://git.infradead.org/linux-mtd Pull MTD updates from Brian Norris: "Generic MTD: - populate the MTD device 'of_node' field (and get a proper 'of_node' symlink in sysfs) This yielded some new helper functions, and changes across a variety of drivers - partitioning cleanups, to prepare for better device-tree based partitioning in the future Eliminate a lot of boilerplate for drivers that want to use OF-based partition parsing The DT bindings for this didn't settle yet, so most non-cleanup portions are deferred for a future release NAND: - embed a struct mtd_info inside struct nand_chip This is really long overdue; too many drivers have to do the same silly boilerplate to allocate and link up two "independent" structs, when in fact, everyone is assuming there is an exact 1:1 relationship between a NAND chips struct and its underlying MTD.

Power management and ACPI updates for v4.5-rc1
- Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki). In particular, the previously added erroneous support for the _SUB object is dropped, the concatenate operator will support all ACPI objects now, the Debug Object handling is improved, the SuperName handling of parameters being control methods is fixed, the ObjectType operator handling is updated to follow ACPI 5.0A and the handling of CondRefOf and RefOf is updated accordingly, module-level code will be executed after loading each ACPI table now (instead of being run once after all tables containing AML have been loaded), the Operation Region handlers management is updated to fix some reported problems and a the ACPICA code in the kernel is more in line with the upstream now. - Update the ACPI backlight driver to provide information on whether or not it will generate key-presses for brightness change hotkeys and update some platform drivers (dell-wmi, thinkpad_acpi) to use that information to avoid sending double key-events to users pace for these, add new ACPI backlight quirks (Hans de Goede, Aaron Lu, Adrien Schildknecht). - Improve the ACPI handling of interrupt GPIOs (Christophe Ricard). - Fix the handling of the list of device IDs of device objects found in the ACPI namespace and add a helper for checking if there is a device object for a given device ID (Lukas Wunner). - Change the logic in the ACPI namespace scanning code to create struct acpi_device objects for all ACPI device objects found in the namespace even if _STA fails for them which helps to avoid device enumeration problems on Microsoft Surface 3 (Aaron Lu). - Add support for the APM X-Gene ACPI I2C device to the ACPI driver for AMD SoCs (Loc Ho). - Fix the long-standing issue with the DMA controller on Intel SoCs where ACPI tables have no power management support for the DMA controller itself, but it can be powered off automatically when the last (other) device on the SoC is powered off via ACPI and clean up the ACPI driver for Intel SoCs (acpi-lpss) after previous attempts to fix that problem (Andy Shevchenko). - Assorted ACPI fixes and cleanups (Andy Lutomirski, Colin Ian King, Javier Martinez Canillas, Ken Xue, Mathias Krause, Rafael Wysocki, Sinan Kaya). - Update the device properties framework for better handling of built-in properties, add support for built-in properties to the platform bus type, update the MFD subsystem's handling of device properties and add support for passing default configuration data as device properties to the intel-lpss MFD drivers, convert the designware I2C driver to use the unified device properties API and add a fallback mechanism for using default built-in properties if the platform firmware fails to provide the properties as expected by drivers (Andy Shevchenko, Mika Westerberg, Heikki Krogerus, Andrew Morton). - Add new Device Tree bindings to the Operating Performance Points (OPP) framework and update the exynos4412 DT binding accordingly, introduce debugfs support for the OPP framework (Viresh Kumar, Bartlomiej Zolnierkiewicz). - Migrate the mt8173 cpufreq driver to the new OPP bindings (Pi-Cheng Chen). - Update the cpufreq core to make the handling of governors more efficient, especially on systems where policy objects are shared between multiple CPUs (Viresh Kumar, Rafael Wysocki). - Fix cpufreq governor handling on configurations with CONFIG_HZ_PERIODIC set (Chen Yu). - Clean up the cpufreq core code related to the boost sysfs knob support and update the ACPI cpufreq driver accordingly (Rafael Wysocki). - Add a new cpufreq driver for ST platforms and corresponding Device Tree bindings (Lee Jones). - Update the intel_pstate driver to allow the P-state selection algorithm used by it to depend on the CPU ID of the processor it is running on, make it use a special P-state selection algorithm (with an IO wait time compensation tweak) on Atom CPUs based on the Airmont and Silvermont cores so as to reduce their energy consumption and improve intel_pstate documentation (Philippe Longepe, Srinivas Pandruvada). - Update the cpufreq-dt driver to support registering cooling devices that use the (P * V^2 * f) dynamic power draw formula where V is the voltage, f is the frequency and P is a constant coefficient provided by Device Tree and update the arm_big_little cpufreq driver to use that support (Punit Agrawal). - Assorted cpufreq driver (cpufreq-dt, qoriq, pcc-cpufreq, blackfin-cpufreq) updates (Andrzej Hajda, Hongtao Jia, Jacob Tanenbaum, Markus Elfring). - cpuidle core tweaks related to polling and measured_us calculation (Rik van Riel). - Removal of modularity from a few cpuidle drivers (clps711x, ux500, exynos) that cannot be built as modules in practice (Paul Gortmaker). - PM core update to prevent devices from being probed during system suspend/resume which is generally problematic and may lead to inconsistent behavior (Grygorii Strashko). - Assorted updates of the PM core and related code (Julia Lawall, Manuel Pégourié-Gonnard, Maruthi Bayyavarapu, Rafael Wysocki, Ulf Hansson). - PNP bus type updates (Christophe Le Roy, Heiner Kallweit). - PCI PM code cleanups (Jarkko Nikula, Julia Lawall). - cpupower tool updates (Jacob Tanenbaum, Thomas Renninger). / -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.22 (GNU/Linux) iQIcBAABCAAGBQJWlZOmAAoJEILEb/54YlRxxtEP/ioR0xMOJQcWd5F6Oyj1PZsx vJeXsmL3fXFAlr6riaE966QqclhUTDhhex3kbFmNQvM8WukxOmBWy5UMSjRg2UmM PHrogc/KrrE+xb8hjGZPgqVr+/L9O3C6lZmM+AUciT0hWZJckYgRh5TpHb1xN/Kx MptvtSXRBM62LWytug+EwA4SHt7OFS0yJ/CI1pKvODVtLaYDIPI5k+4ilPU7y6Be vfoysvmUozNTEYxgPOPXfoQqW2P5t2df32Re31uKtLenLXbc8KW0wIYm24DXgSK6 V/TyDVZTNaZk6OpTqWrjqFbedpGvcBpViwYEY7yv33GDCpXGdHQl3ga+Jy6PAUem 7oGDZtA+5Di/8szhH/wSdpXwSaKEeUdFiaj6Uw2MAwiY4wzv5+WmLRcuIjQFDAxT elrTbQhAgaMlMsUkQ9NV4GC7ByUeeQX2NpCielsHngOQgKdYRQHyYUgGXc2Wgjdq UnVrIWRHzXSED0RtPI7IT0Y4PSxkM9UoSEiVUwt3srCue2CFzuENs23qaDgAzeDa 5uwnDl4RhI2BrLVT1WhioIFgFE5Yh5Xx6dSGC+jcU2ss8r2oN6DdUbqOzWAa1iR4 sFhgwwwizpCCfB6pSqEuDdg8W56HjvE9kQY9kcTPPNPbktL0VImC+iiSN/CgZJv9 MH9NbQM8uHkfNcpjsN7V =OlYA -----END PGP SIGNATURE----- Merge tag 'pm+acpi-4.5-rc1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull oower management and ACPI updates from Rafael Wysocki: "As far as the number of commits goes, ACPICA takes the lead this time, followed by cpufreq and the device properties framework changes. The most significant new feature is the debugfs-based interface to the ACPICA's AML debugger added in the previous cycle and a new user space tool for accessing it. On the cpufreq front, the core is updated to handle governors more efficiently, particularly on systems where a single cpufreq policy object is shared between multiple CPUs, and there are quite a few changes in drivers (intel_pstate, cpufreq-dt etc). The device properties framework is updated to handle built-in (ie included in the kernel itself) device properties better, among other things by adding a fallback mechanism that will allow drivers to provide default properties to be used in case the plaform firmware doesn't provide the properties expected by them. The Operating Performance Points (OPP) framework gets new DT bindings and debugfs support. A new cpufreq driver for ST platforms is added and the ACPI driver for AMD SoCs will now support the APM X-Gene ACPI I2C device. The rest is mostly fixes and cleanups all over. Specifics: - Add a debugfs-based interface for interacting with the ACPICA's AML debugger introduced in the previous cycle and a new user space tool for that, fix some bugs related to the AML debugger and clean up the code in question (Lv Zheng, Dan Carpenter, Colin Ian King, Markus Elfring). - Update ACPICA to upstream revision 20151218 including a number of fixes and cleanups in the ACPICA core (Bob Moore, Lv Zheng, Labbe Corentin, Prarit Bhargava, Colin Ian King, David E Box, Rafael Wysocki).

arm: define __smp_xxx
This defines __smp_xxx barriers for arm, for use by virtualization. smp_xxx barriers are removed as they are defined correctly by asm-generic/barriers.h This reduces the amount of arch-specific boiler-plate code.

arm: reuse asm-generic/barrier.h
On arm smp_store_mb, read_barrier_depends, smp_read_barrier_depends, smp_store_release, smp_load_acquire, smp_mb__before_atomic and smp_mb__after_atomic match the asm-generic variants exactly. Drop the local definitions and pull in asm-generic/barrier.h instead. This is in preparation to refactoring this code area. Signed-off-by: Michael S.
