Linus Torvalds 30f05309bd 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).

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.

  Some more bugs are fixed and cleanups are made on top of that.

  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).

Linus Torvalds 6d1c244803 ARM: DT updates for v4.5
As usual, the bulk of this release is again DT file contents.
 
 There's a huge number of changes here, and it's challenging to give a crisp
 overview of just what is in here. To start with:
 
 New boards:
 
 - TI-based DM3730 from LogicPD (Torpedo)
 - Cosmic+ M4 (nommu) initial support (Freescale Vybrid)
 - Raspberry Pi 2 DT files
 - Watchdog on Meson8b
 - Veyron-mickey (ASUS Chromebit) DTS
 - Rockchip rk3228 SoC and eval board
 - Sigma Designs Tango4
 
 Improvements:
 
 - Improved support for Qualcomm APQ8084, including Sony Xperia Z DT files
 - Misc new devices for Rockchip rk3036 and rk3288
 - Allwinner updates for misc SoCs and systems
 
 ... and a _large_ number of other changes across the field. Devices
 added to SoC DTSI and board DTS files for a number of SoC vendors, new
 product boards on already-supported SoCs, cleanups and refactorings of
 existing DTS/DTSI files and a bunch of other changes.

Linus Torvalds ece6267878 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.

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.  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"

Tomeu Vizoso 989561de9b PM / Domains: add setter for dev.pm_domain
Adds a function that sets the pointer to dev_pm_domain in struct device
and that warns if the device has already finished probing. The reason
why we want to enforce that is because in the general case that can
cause problems and also that we can simplify code quite a bit if we can
always assume that.

This patch also changes all current code that directly sets the
dev.pm_domain pointer.

Tony Lindgren e7b11dc7b7 ARM: OMAP2+: Fix onenand rate detection to avoid filesystem corruption
Commit 63aa945b10 ("memory: omap-gpmc: Add Kconfig option for debug")
unified the GPMC debug for the SoCs with GPMC. The commit also left out
the option for HWMOD_INIT_NO_RESET as we now require proper timings for
GPMC to be able to remap GPMC devices out of address 0.

Unfortunately on Nokia N900, onenand now only partially works with the
device tree provided timings. It works enough to get detected but the
clock rate supported by the onenand chip gets misdetected. This in turn
causes the GPMC timings to be miscalculated and this leads into file
system corruption on N900.

Looks like onenand needs CS_CONFIG1 bit 27 WRITETYPE set for for sync
write. This is needed also for async timings when we write to onenand
with omap2_onenand_set_async_mode(). Without sync write bit set, the
async read for the onenand ONENAND_REG_VERSION_ID will return 0xfff.

Let's exit with an error if onenand rate is not detected. And let's
remove the extra call to omap2_onenand_set_async_mode() as we only need
to do this once at the end of omap2_onenand_setup_async().

Fixes: 63aa945b10 ("memory: omap-gpmc: Add Kconfig option for debug")

Olof Johansson 45e2916be2 SoC changes for omaps for v4.5 merge window. The main change here is to
change the omap initcall levels a bit to initialize things later to allow
 early device drivers at core_initcall level. This makes things easier
 for us as most clocks can be made into regular device drivers except for
 a few early clocks needed to initialize system timers. I wanted to have
 these changes sit in Linux next for a few weeks before sending out a pull
 request, and so far now issues have showed up.
 
 The other changes in this series are timer changes for making use of the
 new PWM driver, and timer changes to support more high security SoCs.
 Also few minor improvments for module autoidle settings for ti81xx spinbox
 and dra7 debug on uart4 in hwmod code. The rest is pretty much just removal
 of platform data for SoCs that are all device tree only nowadays.

Grygorii Strashko 0b3e6fca4d ARM: OMAP2+: am43xx: enable GENERIC_CLOCKEVENTS_BROADCAST
System will misbehave in the following case:
- AM43XX only build (UP);
- CONFIG_CPU_IDLE=y
- ARM TWD timer enabled and selected as clockevent device.

In the above case, It's expected that broadcast timer will be used as
backup timer when CPUIdle will put MPU in low power states where ARM
TWD will stop and lose its context. But, the CONFIG_SMP might not be
selected when kernel is built for AM43XX SoC only and, as result,
GENERIC_CLOCKEVENTS_BROADCAST option will not be selected also. This
will break CPUIdle and System will stuck in low power states.

Hence, fix it by selecting GENERIC_CLOCKEVENTS_BROADCAST option for
AM43XX SoCs always and add empty tick_broadcast() function
implementation - no need to send any IPI on UP. After this change
timer1 will be selected as broadcast timer the same way as for SMP,
and CPUIdle will work properly.

Tony Lindgren 71842a74f9 Merge branch 'omap-for-v4.5/initcall' into omap-for-v4.5/soc-v2 2015-12-03 11:41:28 -08:00
Tony Lindgren 8dd5ea72b0 ARM: OMAP2+: Change core_initcall levels to postcore_initcall
We want to be able to probe a few selected device drivers before hwmod
code populates the clocks in omap_hwmod_setup_all(). This allows us to
convert most of the clock drivers into regular device drivers.

We only need a few minimal clock drivers early for the system timers to
select between the 32KiHz clock and the high frequency oscillator.

With these changes, initializing the clock drivers can be just done at
core_initcall time with something like:

np = of_find_node_by_name(NULL, "plls");
if (np)
	of_platform_populate(np, NULL, NULL, NULL);

And then these clocks will be available for the interconnect code to use.

Having most of the clock drivers being regular device drivers allows
us to use the nice things like devm_* functions and dev_err and dev_dbg.
As an extra bonus, this also allows us to develop the clock drivers for
new SoCs as loadable modules initially for cases where we can boot up
the system based on the bootloader configured clocks.

To do this, let's change the core_initcalls to postcore_initcall under
mach-omap2.

Errata i810 states that DPLL controller can get stuck while transitioning
to a power saving state, while its M/N ratio is being re-programmed.

As a workaround, before re-programming the M/N ratio, SW has to ensure
the DPLL cannot start an idle state transition. SW can disable DPLL
idling by setting the DPLL AUTO_DPLL_MODE=0 or keeping a clock request
active by setting a dependent clock domain in SW_WKUP.

This errata impacts OMAP5 and DRA7 chips, so enable the errata for these.

Tony Lindgren 970259bff4 Merge branch '81xx' into omap-for-v4.4/fixes 2015-11-25 10:56:40 -08:00
Neil Armstrong 29f5b34ca1 arm: omap2+: add missing HWMOD_NO_IDLEST in 81xx hwmod data
Add missing HWMOD_NO_IDLEST hwmod flag for entries not
having omap4 clkctrl values.
The emac0 hwmod flag fixes the davinci_emac driver probe
since the return of pm_resume() call is now checked.

This solves the following boot errors :
[    0.121429] omap_hwmod: l4_ls: _wait_target_ready failed: -16
[    0.121441] omap_hwmod: l4_ls: cannot be enabled for reset (3)
[    0.124342] omap_hwmod: l4_hs: _wait_target_ready failed: -16

Mauro Carvalho Chehab eb4b0ec75e [media] include/media: move platform_data to linux/platform_data/media
Let's not mix platform_data headers with the core headers. Instead, let's
create a subdir at linux/platform_data and move the headers to that
common place, adding it to MAINTAINERS.

The headers were moved with:
	mkdir include/linux/platform_data/media/; git mv include/media/gpio-ir-recv.h include/media/ir-rx51.h include/media/mmp-camera.h include/media/omap1_camera.h include/media/omap4iss.h include/media/s5p_hdmi.h include/media/si4713.h include/media/sii9234.h include/media/smiapp.h include/media/soc_camera.h include/media/soc_camera_platform.h include/media/timb_radio.h include/media/timb_video.h include/linux/platform_data/media/

And the references fixed with this script:
    MAIN_DIR="linux/platform_data/"
    PREV_DIR="media/"
    DIRS="media/"

    echo "Checking affected files" >&2
    for i in $DIRS; do
	for j in $(find include/$MAIN_DIR/$i -type f -name '*.h'); do
		 n=`basename $j`
		git grep -l $n
	done
    done|sort|uniq >files && (
	echo "Handling files..." >&2;
	echo "for i in \$(cat files|grep -v Documentation); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "perl -ne 's,(include [\\\"\\<])$PREV_DIR($i)([\\\"\\>]),\1$MAIN_DIR$j\2\3,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done";
	);
	echo "Handling documentation..." >&2;
	echo "for i in MAINTAINERS \$(cat files); do cat \$i | \\";
	(
		cd include/$MAIN_DIR;
		for j in $DIRS; do
			for i in $(ls $j); do
				echo "  perl -ne 's,include/$PREV_DIR($i)\b,include/$MAIN_DIR$j\1,; print \$_' |\\";
			done;
		done;
		echo "cat > a && mv a \$i; done"
	);
    ) >script && . ./script
