ARM: OMAP2+: sleep33/43xx: Add RTC-Mode support
Add support for RTC mode to low level suspend code. This includes providing the rtc base address for the assembly code to configuring the PMIC_PWR_EN line late in suspend to enter RTC+DDR mode. Note: This patch also fold in left out space parameter for am33xx_emif_sram_table and am43xx_emif_sram_table Signed-off-by: Dave Gerlach <d-gerlach@ti.com> Signed-off-by: Keerthy <j-keerthy@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com> |

ARM: OMAP2+: sleep33/43xx: Make sleep actions configurable
Add an argument to the sleep33xx and sleep43xx code to allow us to set flags to determine which portions of the code get called in order to use the same code for multiple power saving modes. This patch allows us to decide whether or not we flush and disable caches, save EMIF context, put the memory into self refresh and disable the EMIF, and/or invoke the wkup_m3 when entering into WFI.

driver core: Rename flag AUTOREMOVE to AUTOREMOVE_CONSUMER
Now that we want to add another flag to autoremove the device link on supplier unbind, it's fair to rename the existing flag from DL_FLAG_AUTOREMOVE to DL_FLAG_AUTOREMOVE_CONSUMER so that we can add similar flag for supplier later. And, while we are touching device.h, fix a doc build warning. Signed-off-by: Vivek Gautam <vivek.gautam@codeaurora.org> Reviewed-by: Ulf Hansson <ulf.hansson@linaro.org> Signed-off-by: Rafael J.

soc: ti: wkup_m3_ipc: mark PM functions as __maybe_unused
Everyone gets these #ifdefs wrong, leading to another warning here:
drivers/soc/ti/wkup_m3_ipc.c:547:12: error: 'wkup_m3_ipc_resume' defined but not used [-Werror=unused-function]

static int wkup_m3_ipc_suspend(struct device *dev)
The easiest way to get it right is to remove all the #ifdefs and
let the compiler drop the unused functions silently after we
mark them as __maybe_unused.

Renesas ARM Based SoC Arm SoC Updates for v4.19
* Convert to SPDX identifier
* Remove legacy SMP fallback code
Geert Uytterhoeven says "R-Car H2 and M2-W have been supporting SMP
enablement from DT using the "renesas,apmu" enable-method since v4.8.
A legacy fallback was left in place for backwards compatibility with old
DTBs.
This patch series removes the legacy SMP fallbacks for R-Car H2 and
M2-W, and consolidates their support in the common R-Car Gen2 machine
definition.2
* APMU cleanups after legacy SMP fallback removal
- Move cpu_leave_lowpower() from HOTPLUG_CPU || SUSPEND section to the
SUSPEND section as it is only used for suspend
- Remove shmobile_smp_apmu_prepare_cpus() as it is no longer used
- Remove platsmp-apmu.h
* Drop legacy SYSC fallbacks
Geert Uytterhoeven says "When DT SYSC support was introduced in v4.7,
legacy fallbacks were kept to keep secondary CPUs working on R-Car H1,
H2, and M2-W using old DTBs. However, the time has come to drop these
fallbacks, and clean up the resulting code"

soc: bcm: brcmstb: Add missing DDR MEMC compatible strings
We would not be matching the following chip/compatible strings
combinations, which would lead to not setting the warm boot flag
correctly, fix that:
7260A0/B0: brcm,brcmstb-memc-ddr-rev-b.2.1
7255A0: brcm,brcmstb-memc-ddr-rev-b.2.3
7278Bx: brcm,brcmstb-memc-ddr-rev-b.3.1
The B2.1 core (which is in 7260 A0 and B0) doesn't have the
SHIMPHY_ADDR_CNTL_0_DDR_PAD_CNTRL setup in the memsys init code, nor
does it have the warm boot flag re-definition on entry. Those changes
were for B2.2 and later MEMSYS cores. Fall back to the previous S2/S3
entry method for these specific chips.

Merge tag 'overflow-v4.18-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux
Pull more overflow updates from Kees Cook:
"The rest of the overflow changes for v4.18-rc1.
This includes the explicit overflow fixes from Silvio, further
struct_size() conversions from Matthew, and a bug fix from Dan.
But the bulk of it is the treewide conversions to use either the
2-factor argument allocators (e.g. kmalloc(a * b, ...) into
kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
b) into vmalloc(array_size(a, b)).
Coccinelle was fighting me on several fronts, so I've done a bunch of
manual whitespace updates in the patches as well.
Summary:
- Error path bug fix for overflow tests (Dan)
- Additional struct_size() conversions (Matthew, Kees)
- Explicitly reported overflow fixes (Silvio, Kees)
- Add missing kvcalloc() function (Kees)
- Treewide conversions of allocators to use either 2-factor argument
variant when available, or array_size() and array3_size() as needed
(Kees)"

treewide: Use array_size() in vzalloc()
The vzalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:
vzalloc(a * b)
with:
vzalloc(array_size(a, b))
as well as handling cases of:
vzalloc(a * b * c)
with:
vzalloc(array3_size(a, b, c))
This does, however, attempt to ignore constant size factors like:
vzalloc(4 * 1024)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
The Coccinelle script used for this was:

treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc().
This patch replaces cases of:
devm_kzalloc(handle, a * b, gfp)
with:
devm_kcalloc(handle, a * b, gfp)
as well as handling cases of:
devm_kzalloc(handle, a * b * c, gfp)
with:
devm_kzalloc(handle, array3_size(a, b, c), gfp)
as it's slightly less ugly than:
devm_kcalloc(handle, array_size(a, b), c, gfp)
This does, however, attempt to ignore constant size factors like:
devm_kzalloc(handle, 4 * 1024, gfp)
though any constants defined via macros get caught up in the conversion.
Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.
Some manual whitespace fixes were needed in this patch, as Coccinelle
really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...".

ARM: SoC: late updates
This is a branch with a few merge requests that either came in late, or took a while longer for us to review and merge than usual and thus cut it a bit close to the merge window. We stage them in a separate branch and if things look good, we still send them up -- and that's the case here. This is mostly DT additions for Renesas platforms, adding IP block descriptions for existing and new SoCs. There are also some driver updates for Qualcomm platforms for SMEM/QMI and GENI, which is their generalized serial protocol interface. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlsfCVIPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3KOcP/3O2+igstXt5rhemITdyi8rHkrIHPgetf25e ISBQzYrQOHV21SqT4le/Gk2CCQ6iX5Nv2DYoIrCzFWi/4DoDxXvryczQLla02Nru i8fcuxae7aFGW7/97G1+cATGPwuBLPiKXs6Wj01sKHeLBja5Det7eoXuHag7Y/Lo 4ls9wNZybMdlCcGm6+ULdj+XUdRyYUhOQQYvnPm2Q8hEkM+AiwLOBJTFwef9P5ad mX37kPDfwCxYwQXgZB1RkK/oJu0G2mTZXmGH5o+s+9yAyAupCQhmHGOrt3mlOf7j tLRlSgarJlO/QGIpJmDuCcxt3msD3OMd2dPbdgwojdpvycOU8EVWYLmCRpyIWQXv DCv9A9Gp4KlJnwxheVegBtilRA1aKsGuarWq6yeyOFt8N23Bgg/IjYKI9JF5+hPD M4q1oVAbUlfWb79rEc+TB0d7euREBkNn4TzzKMSOyP3eGUrXR0WUlq2A2VLxgIJo cx/ufY7CwvRgV+VxfhRbca+FmwDnu7uqzwLe73Ys2hnsuv8hXEtc+vSybqKqxVeU nHpWAqwaWhijlJiGq722vPo8avrLwjsxRwimogvijtesz9ZlTqrGtjkg61+eN2h8 eeuyRAsMUfVRiKuL3W+q4s0rzIauormnKsvRScKVyNFuiJfrfYb1odLoDGaOV/9G dQ7hA7TW =RUL0 -----END PGP SIGNATURE----- Merge tag 'armsoc-late' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC late updates from Olof Johansson: "This is a branch with a few merge requests that either came in late, or took a while longer for us to review and merge than usual and thus cut it a bit close to the merge window.

ARM: SoC platform updates
Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms. The branch also contains defconfig updates to turn on drivers and options as needed on the various platforms. The largest parts of the delta are from cleanups moving platform data and board file setup of TI platforms to ti-sysc bus drivers. There are also some sweeping changes of eeprom and nand setup on Davinci, i.MX and other platforms. Samsung is removing support for Exynos5440, which was an oddball SoC that hasn't been seen much use in designs. Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D). Linus Walleij is also removing support for ux500 (Sony Ericsson) U8540/9540 SoCs that never made it to significant mass production and products. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlsfCGIPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3Ks8P/3j87Za+6OTCzo+lW2byUy1CI4muGwxNSIxX 65A1Wt2qvRDxjCX4MI5Cx8P1YdYJv+5ZF2p4vdlgQXoz3/XDbG+lxJ+/lyWl/+MK 9kGsQWwEVicbGkaJCYR4ZKvfAwZ9jf7+cndY0Vgii44xQLsQZHEIfIO+mdlK43GZ xqaSckLQQzsDqjMUIckiyVy97RsDk1eLK+H2I+l7qs9v0z5UnhoD2CTxX5LzT8eH NlFmfUPN7Znshmt0aMznZyBRr2oM5Dsg49SfG0WhbOzyiZjSpw8MQ0N+RzyROhhB h5PjyuZN9fx2dO8Jjkqt3B8KmGFNDarGOmrasIJeCJDFRa9NStqFn0y4qJXS2wU7 4La3GoBYRV8x0gq339pQ+70qKuD06e62GL7kV656yi+93CitWxy6IjrIACjSX6zH PD1hQpewfXAcHAHdBqNevRcz/sjG+36GJSCgI4umSP48NMlCuZafFAT4U/PVlt4E 6VRQDeoi5ZFYIuPL1+bZvHax4fFxJGnaf02uQ/OPYP1o48AueSSvdo6bUPFbhwOD u0/uo3r+HxtQsw9I3tP3kj3/775BJclkO6zbG/dGZ8obuzuDwhuFtr3rzCrP/IzN n3rcBuFNZE6SQeKU+Tvmnh8ZLhJc5L8EYvqmihZj+BSfprBc8POFR2la4MRnHSn+ tPEC/n9E =S5wc -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Olof Johansson: "Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms.

This time we have a good set of changes to the core framework that do some
general cleanups, but nothing too major. The majority of the diff goes to two SoCs, Actions Semi and Qualcomm. A brand new driver is introduced for Actions Semi so it takes up some lines to add all the different types, and the Qualcomm diff is there because we add support for two SoCs and it's quite a bit of data. Otherwise the big driver updates are on TI Davinci and Amlogic platforms. And then the long tail of driver updates for various fixes and stuff follows after that. Core: - debugfs cleanups removing error checking and an unused provider API - Removal of a clk init typedef that isn't used - Usage of match_string() to simplify parent string name matching - OF clk helpers moved to their own file (linux/of_clk.h) - Make clk warnings more readable across kernel versions New Drivers: - Qualcomm SDM845 GCC and Video clk controllers - Qualcomm MSM8998 GCC - Actions Semi S900 SoC support - Nuvoton npcm750 microcontroller clks - Amlogic axg AO clock controller Removed Drivers: - Deprecated Rockchip clk-gate driver Updates: - debugfs functions stopped checking return values - Support for the MSIOF module clocks on Rensas R-Car M3-N - Support for the new Rensas RZ/G1C and R-Car E3 SoCs - Qualcomm GDSC, RCG, and PLL updates for clk changes in new SoCs - Berlin and Amlogic SPDX tagging - Usage of of_clk_get_parent_count() in more places - Proper implementation of the CDEV1/2 clocks on Tegra20 - Allwinner H6 PRCM clock support and R40 EMAC support - Add critical flag to meson8b's fdiv2 as temporary fixup for ethernet - Round closest support for meson's mpll driver - Support for meson8b nand clocks and gxbb video decoder clocks - Mediatek mali clks - STM32MP1 fixes - Uniphier LD11/LD20 stream demux system clock -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE9L57QeeUxqYDyoaDrQKIl8bklSUFAlsWxugACgkQrQKIl8bk lSVs2A/9HOMsWeiYx1MESrXw6N2UknWeqeT/b1v8L/VOiptJg+OTExPbzmSylngv AXJAfIkCpguSMh9b310pA3DAzk5docmbQ4zL977yY+KXmOcDooCd34aG5a+tB3ie ugC8T2bQLrJdMp3hsqaKZsYzqe7LoW2NJgoliXDMA/QUBLpvHq+fcu2zOawingTA GNc3LGqP5Op7p09aPK30gtQNqLK5qGpHASa/AY7Y0PXlUeTZ8rmF06fcEAg5shkC CT57Zy2rSFB2RorEJarYXDPLRHMw/jxXtpMVXEy7zuz/3ajvvRiZDHv75+NaBru9 hDt1rzslzexEN4fYzj4AtGYRKyBrHbDaxG1qdIWPWVyoE0CEb+dZ1gH7/Ski5r+s z5D28NogC0T0sey6yWssyG3RLvkPJ5nxUhL++siHm1lbyo16LmhB1+nFvxrlzmBB 0V1xqEa7feYpD+JD66lJFb5ornHLwGtVYBpeiY+hrDR3ddWEe1IxaYGR2p9nHwSS Us/ZQdHIYBVEqoo3+BWnTn+HSQzmd/sqHqWnLlVWUHoomm5nXx18PeS87vFbcPv9 dMr+FFJ3Elubzcy5UZJPfNw+pb+teE7tYGQkQ3nbLRxT1YZOoIJZJDqNKxM1cgne 6c/VXJMEyBBn/w7Iru/3eWCZVQJGlmYS47DFDzduFvd3LMfmKIM= =KK/v -----END PGP SIGNATURE----- Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux Pull clk updates from Stephen Boyd: "This time we have a good set of changes to the core framework that do some general cleanups, but nothing too major.

Pull overflow updates from Kees Cook:
"This adds the new overflow checking helpers and adds them to the
2-factor argument allocators. And this adds the saturating size
helpers and does a treewide replacement for the struct_size() usage.
Additionally this adds the overflow testing modules to make sure
everything works.
I'm still working on the treewide replacements for allocators with
"simple" multiplied arguments:
*alloc(a * b, ...) -> *alloc_array(a, b, ...)
and
*zalloc(a * b, ...) -> *calloc(a, b, ...)
as well as the more complex cases, but that's separable from this
portion of the series. I expect to have the rest sent before -rc1
closes; there are a lot of messy cases to clean up.

- Use overflow helpers in 2-factor allocators (Kees, Rasmus)

initialization and removal of devices using device links (Ulf
Hansson).
- Clean up the initialization of drivers for devices in PM domains
(Ulf Hansson, Geert Uytterhoeven).

- Add a new cpufreq driver for Qualcomm Kryo (Ilia Lin).
- Fix and clean up some cpufreq drivers (Colin Ian King, Dmitry
Osipenko, Doug Smythies, Luc Van Oostenryck, Simon Horman,
Viresh Kumar).
- Fix the handling of PCI devices with the DPM_SMART_SUSPEND flag
set and update stale comments in the PCI core PM code (Rafael
Wysocki).

events in the ACPI PM core during resume from suspend-to-idle if
the EC has been put into the low-power mode (Rafael Wysocki).
- Improve the handling of wakeup source objects in the PM core (Doug
Berger, Mahendran Ganesh, Rafael Wysocki).
- Update the driver core to prevent deferred probe from breaking
suspend/resume ordering (Feng Kan).
- Clean up the PM core somewhat (Bjorn Helgaas, Ulf Hansson, Rafael
Wysocki).

(Sebastian Andrzej Siewior, Thomas Gleixner).
- Consolidate the PM QoS handling in cpuidle governors (Rafael
Wysocki).
- Fix a possible crash in the hibernation core (Tetsuo Handa).
- Update the rockchip-io Adaptive Voltage Scaling (AVS) driver
(David Wu).

soc: qcom: qmi: fix a buffer sizing bug
In qmi_handle_init(), a buffer is allocated for to hold messages received through the handle's socket. Any "normal" messages (expected by the caller) will have a header prepended, so the buffer size is adjusted to accomodate that. The buffer must also be of sufficient size to receive control messages, so the size is increased if necessary to ensure these will fit. Unfortunately the calculation is done wrong, making it possible for the calculated buffer size to be too small to hold a "normal" message. Specifically, if: recv_buf_size > sizeof(struct qrtr_ctrl_pkt) - sizeof(struct qmi_header) AND recv_buf_size < sizeof(struct qrtr_ctrl_pkt) the current logic will use sizeof(struct qrtr_ctrl_pkt) as the receive buffer size, which is not enough to hold the maximum "normal" message plus its header. Currently this problem occurs for (13 < recv_buf_size < 20). This patch corrects this.

Two places report an error when a partition header is found to not contain the right canary value. The error messages do not properly byte swap the host ids. Fix this, and adjust the format specificier to match the 16-bit unsigned data type. Move the error handling for a bad canary value to the end of qcom_smem_alloc_private().

What phdr_to_last_uncached_entry() returns is the address of the start of the free space following all allocated uncached entries. It really doesn't refer to an actual (initialized) private entry structure. Similarly phdr_to_last_cached_entry() returns the address of the end of free space, preceding the last allocated cache entry. Change both functions' return type to be pointer to void to reflect this. Meanwhile, phdr_to_first_cached_entry() really *does* point to a private entry structure, so change its return type to reflect this fact.

soc: qcom: smem: fix first cache entry calculation
Cached items are found at the high end of an smem partition. A cached item's shared memory precedes the private entry structure that describes it. The address of the structure describing the first cached item should be returned by phdr_to_first_cached_entry(). However the function calculates the start address using the wrong structure size. Fix this by computing the first item's entry structure address by subtracting the size of a private entry structure rather than a partition header structure.

MIPS: lantiq: gphy: Drop reboot/remove reset asserts
While doing a global software reset, these bits are not cleared and let
some bootloader fail to initialise the GPHYs. The bootloader don't
expect the GPHYs in reset, as they aren't during power on.
The asserts were a workaround for a wrong syscon-reboot mask. With a
mask set which includes the GPHY resets, these resets aren't required
any more.

soc: mediatek: add a fixed wait for SRAM stable
MT7622_POWER_DOMAIN_WB doesn't send an ACK when its managed SRAM becomes stable, which is not like the behavior the other power domains should have. Therefore, it's necessary for such a power domain to have a fixed and well-predefined duration to wait until its managed SRAM can be allowed to access by all functions running on the top.

This patch provide APIs to allow client drivers to support probe deferral. On K2G SoC, devices can be probed only after the ti_sci_pm_domains driver is probed and ready. As drivers may get probed at different order, any driver that depends on knav dma and qmss drivers, for example netcp network driver, needs to defer probe until knav devices are probed and ready to service. To do this, add an API to query the device ready status from the knav dma and qmss devices. Signed-off-by: Murali Karicheri <m-karicheri2@ti.com> Signed-off-by: David S.

soc: ti: K2G: enhancement to support QMSS in K2G NAVSS
Navigator Subsystem (NAVSS) available on K2G SoC has a cut down version of QMSS with less number of queues, internal linking ram with lesser number of buffers etc. It doesn't have status and explicit push register space as in QMSS available on other K2 SoCs. So define reg indices specific to QMSS on K2G. This patch introduces "ti,66ak2g-navss-qm" compatibility to identify QMSS on K2G NAVSS and to customize the dts handling code. Per Device manual, descriptors with index less than or equal to regions0_size is in region 0 in the case of K2 QMSS where as for QMSS on K2G, descriptors with index less than regions0_size is in region 0. So update the size accordingly in the regions0_size bits of the linking ram size 0 register.

The large diff this time around is from the addition of a new clk driver
for the TI Davinci family of SoCs. So far those clks have been supported with a custom implementation of the clk API in the arch port instead of in the CCF. With this driver merged we're one step closer to having a single clk API implementation. The other large diff is from the Amlogic clk driver that underwent some major surgery to use regmap. Beyond that, the biggest hitter is Samsung which needed some reworks to properly handle clk provider power domains and a bunch of PLL rate updates. The core framework was fairly quiet this round, just getting some cleanups and small fixes for some of the more esoteric features. And the usual set of driver non-critical fixes, cleanups, and minor additions are here as well.

ARM: SoC driver updates for 4.17
The main addition this time around is the new ARM "SCMI" framework,
which is the latest in a series of standards coming from ARM to do power
management in a platform independent way. This has been through many
review cycles, and it relies on a rather interesting way of using the
mailbox subsystem, but in the end I agreed that Sudeep's version was
the best we could do after all.
Other changes include:
- the ARM CCN driver is moved out of drivers/bus into drivers/perf,
which makes more sense. Similarly, the performance monitoring
portion of the CCI driver are moved the same way and cleaned up
a little more.
- a series of updates to the SCPI framework
- support for the Mediatek mt7623a SoC in drivers/soc
- support for additional NVIDIA Tegra hardware in drivers/soc
- a new reset driver for Socionext Uniphier
- lesser bug fixes in drivers/soc, drivers/tee, drivers/memory, and
drivers/firmware and drivers/reset across platforms

ARM: SoC platform updates for 4.17
This release brings up a new platform based on the old ARM9 core: the Nuvoton NPCM is used as a baseboard management controller, competing with the better known ASpeed AST2xx series. Another important change is the addition of ARMv7-A based chips in mach-stm32. The older parts in this platform are ARMv7-M based microcontrollers, now they are expanding to general-purpose workloads. The other changes are the usual defconfig updates to enable additional drivers, lesser bugfixes. The largest updates as often are the ongoing OMAP cleanups, but we also have a number of changes for the older PXA and davinci platforms this time. For the Renesas shmobile/r-car platform, some new infrastructure is needed to make the watchdog work correctly. Supporting Multiprocessing on Allwinner A80 required a significant amount of new code, but is not doing anything unexpected. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQIcBAABAgAGBQJaxibSAAoJEGCrR//JCVInPwcP/2ZdLMXXXaJBM+rCRPhT+vR1 FsKqcTCC5RHbVcKW+N54nmlsqofy2GadlmyfOdrFXtbf+Sm2dRNsDrHDOhvoPp37 fwBd0wGw0PLjNE8SEPp/ldtFe11Dbg0WGBzJ4PAPJgt1W4hvW8//VzVW1XsiRrVc 9SlZ66DwR95UQ5pwy+dfE8f9A/WW4XaMq0UHQ3/deQ/Te/64b/C6CJtT3W73WAlR 83UHgkwq3WvI+hhvg4QX9H0Q6dcK2JLUWsAB0xnZP8Q8t30NdDpl61uZL0A4Mh9Y 38lPhUjPUyUpsGrOttmMEQNzbAk4m/nzQxByYYmhkx3x+mlhjdA9KNavxDYVxXN2 1tzz62wst8pLePqVt2UsFqsaruJGMuTIooOdc5iCjG1c2N2kQGdBsuOvLjYu9kV6 XPTfvvAYkMo9rC0MbdPuobG+h/WrYHuc9SD2Mnt+kNaw1yJL08fWENjSuwP7kheb 2A5jdAFNrGqgcrWMsQOw8eYYC7z7WojkLq0kHrBbwIlVD7KIZurv2fm/iVo4+xPH Gig5HuehMUtVYAf+Q1KWFlqS01fXMErt2pDGI5f1mNumXCB5kdWoSKbU8lOg03f8 ZqBHlfly+QDMOx0qfkxFX+phHPWHTOC+45yHK2Xq+n9urXmQbzYZxTzq5zCu6jcm 4yH0jaykoHODGNLIt50f =HD9V -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Arnd Bergmann: "This release brings up a new platform based on the old ARM9 core: the Nuvoton NPCM is used as a baseboard management controller, competing with the better known ASpeed AST2xx series.

ARM: SoC device tree updates for 4.17
This is the usual set of changes for device trees, with over 700
non-merged changesets. There is an ongoing set of dtc warning fixes and
the usual bugfixes, cleanups and added device support.
The most interesting bit as usual is support for new machines listed
below:
- The Allwinner H6 makes its debut with the Pine-H64 board, and we get
two new machines based on its older siblings: the H5 based OrangePi
Zero+ and the A64 based Teres-I Laptop from Olimex. On the 32-bit side,
we add The Olimex som204 based on Allwinner A20, and the Banana Pi M2
Zero development board (based on H2).
- NVIDIA adds support for Tegra194 aka "Xavier", plus their p2972
development board and p2888 CPU module.
- The Nuvoton npcm750 is a BMC that was newly added, for now we only
support running on the evaluation board.
- STmicroelectronics stm32 gains support for the stm32mp157c and two
evaluation boards.
- The Toradex Colibri board family grows a few members based on the
i.MX6ULL variant.
- The Advantec DMS-BA16 is a Qseven module using the NXP i.MX6
family of chips.
- The Phytec phyBOARD Mira is a family of industrial boards based on
i.MX6. For now, four models get added.
- TI am335x based PDU-001 is an industrial embedded machine used for
traffic monitoring
- The Aspeed platform now supports running on the BMC on the Qualcomm
Centriq 2400 server
- Samsung Exynos4 based Galaxy S3 is a family of mobile phones Qualcomm
msm8974 based Galaxy S5 is a rather different phone made by the same
company.
- The Xilinx Zynq and ZynqMP platforms now gained a lot of dts file
for the various boards made by Xilinx themselves, as well as the
Digilent Zybo Z7.
- The ARM Versatile family now supports the "IB2" interface board.
- The Renesas H2 based "Stout" and the H3 based Salvator-X are more
evaluation boards named after a kind of beer, as most of them are.
The r8a77980 (V3H) based "Condor" apparently doesn't follow that
tradition. ;-)
- ROC-RK3328-CC is a simple developement board from the Libre Computer
Project, based on the Rockchips RK3328 SoC
- Haiku is another development board plus Qseven module based on Rockchips
RK3368 and made by Theobroma Systems.
