Mauro Carvalho Chehab 64131a87f2 Merge branch 'drm-next-merged' of git://people.freedesktop.org/~airlied/linux into v4l_for_linus
* 'drm-next-merged' of git://people.freedesktop.org/~airlied/linux: (9717 commits)
  media-bus: Fixup RGB444_1X12, RGB565_1X16, and YUV8_1X24 media bus format

  sparc: Make sparc64 use scalable lib/iommu-common.c functions
  Break up monolithic iommu table/lock into finer graularity pools and lock
  sparc: Revert generic IOMMU allocator.
  tools/power turbostat: correct dumped pkg-cstate-limit value
  tools/power turbostat: calculate TSC frequency from CPUID(0x15) on SKL
  tools/power turbostat: correct DRAM RAPL units on recent Xeon processors
  tools/power turbostat: Initial Skylake support
  tools/power turbostat: Use $(CURDIR) instead of $(PWD) and add support for O= option in Makefile
  tools/power turbostat: modprobe msr, if needed
  tools/power turbostat: dump MSR_TURBO_RATIO_LIMIT2
  tools/power turbostat: use new MSR_TURBO_RATIO_LIMIT names
  Bluetooth: hidp: Fix regression with older userspace and flags validation
  config: Enable NEED_DMA_MAP_STATE by default when SWIOTLB is selected
  perf/x86/intel/pt: Fix and clean up error handling in pt_event_add()
  ...

That solves several merge conflicts:
	Documentation/DocBook/media/v4l/subdev-formats.xml
	Documentation/devicetree/bindings/vendor-prefixes.txt
	drivers/staging/media/mn88473/mn88473.c
	include/linux/kconfig.h
	include/uapi/linux/media-bus-format.h

The ones at subdev-formats.xml and media-bus-format.h are not trivial.
That's why we opted to merge from DRM.

Tony Lindgren da4d81453c ARM: OMAP2+: Fix booting with configs that don't have MFD_SYSCON
With the recent changes omaps have developed a dependency to MFD_SYSCON.
This is used for system control module generic register area and some
clocks.

We do have it selected in omap2plus_defconfig, but targeted config
files may not have it selected. Let's make sure it's selected like
few other ARM platforms are already doing.

Merge tag 'pm+acpi-4.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI updates from Rafael Wysocki:
 "These are mostly fixes and cleanups all over, although there are a few
  items that sort of fall into the new feature category.

  First off, we have new callbacks for PM domains that should help us to
  handle some issues related to device initialization in a better way.

  There also is some consolidation in the unified device properties API
  area allowing us to use that inferface for accessing data coming from
  platform initialization code in addition to firmware-provided data.

  We have some new device/CPU IDs in a few drivers, support for new
  chips and a new cpufreq driver too.

  Specifics:

   - Generic PM domains support update including new PM domain callbacks
     to handle device initialization better (Russell King, Rafael J
     Wysocki, Kevin Hilman)

mode on the latter. This paves the way for CCI-500 support in future.

Sakari Ailus 6890874772 [media] omap3isp: Refactor device configuration structs for Device Tree
Make omap3isp configuration data structures more suitable for consumption by
the DT by separating the I2C bus information of all the sub-devices in a
group and the ISP bus information from each other. The ISP bus information
is made a pointer instead of being directly embedded in the struct.

In the case of the DT only the sensor specific information on the ISP bus
configuration is retained. The structs are renamed to reflect that.

After this change the structs needed to describe device configuration can be
allocated and accessed separately without those needed only in the case of
platform data. The platform data related structs can be later removed once
the support for platform data can be removed.

Andreas Fenkart b7a5646fa5 ARM: OMAP2: HSMMC: explicit fields to declare cover/card detect pin
board-rx51 has no card detect pin in the mmc slot, but can detect that
the (cell-phone) cover has been removed and the card is accessible.
The semantics between cover/card detect differ, the gpio on the slot
informs you after the card has been removed, cover removal does not
necessarily mean that the card has been removed.
This means different code paths are necessary. To complete this we
also want different fields in the platform data for cover and card
detect. This separation is not pushed all the way down into struct
omap2_hsmmc_info which is used to initialize the platform data.
If we did that we had to go over all board files and set the new
gpio_cod pin to -EINVAL. If we forget one board or some out-of-tree
archicture forgets that the default '0' is used which is a valid pin
number.

Daniel Lezcano eeebc3bb4d ARM: cpuidle: Remove duplicate header inclusion
The cpu_do_idle() function is always used by the cpuidle drivers.

That led to have each driver including cpuidle.h and proc-fns.h, they are
always paired. That makes a lot of duplicate headers inclusion. Instead of

Luciano Coelho 6f921fab58 wlcore: set irq_trigger in board files instead of hiding behind a quirk
The platform_quirk element in the platform data was used
to change the way the IRQ is triggered.  When set,
the EDGE_IRQ quirk would change the irqflags used
and treat edge trigger differently from the rest.

Instead of hiding this irq flag setting behind the quirk,
have the board files set the irq_trigger explicitly.

This will allow us to use standard irq DT definitions
later on.

Tony Lindgren 01ea0d4247 ARM: OMAP2+: Remove legacy support for omap3 TouchBook
We've been moving all omap2+ based systems to boot in device tree only
mode for a few years now. Only omap3 has legacy booting support
remaining. Most omap3 boards already have related arch/arm/boot/*.dts*
files for booting with device tree.

As it seems this board only has minimal support upstreamed for the
legacy booting and has not seen activity for on the mailing lists
for a few years, let's attempt to remove the related legacy board-*.c
file.

I do not have this board, but it seems getting the same level of
support with device tree based booting is mostly just configuring
the .dts file. And there is no need to upgrade the boot loader as
we can boot with appended DTB too. And most of the omap3 boards
seem to be related to omap3-evm, and omap3beagleboard that are
supported with device tree based booting.

If somebody is using this board actively with the mainline kernel,
please communicate this to the linux-omap mailing list so we can
get the board booting with device tree based support. I can help
some too getting the minimal device tree based booting going if
help is needed.

The reason for attempting to remove this board now is that I'd
rather get the remaining omap3 legacy booting support into a known
state where we at least have a .dts file being written for the
remaining legacy boards. That is because for the next few merge
cycles we can still revert this patch if absolutely necessary,
but I'd rather not get suprised by missing .dts files at the point
where we are ready to drop all remaining omap3 legacy booting
support later on.

Stefan Hengelein 606da4826b ARM: OMAP4: remove dead kconfig option OMAP4_ERRATA_I688
The Kconfig-Option OMAP4_ERRATA_I688 is never visible due to a
contradiction in it's dependencies.
The option requires ARCH_MULTIPLATFORM to be 'disabled'. However, an
enclosing menu requires either ARCH_MULTI_V6 or ARCH_MULTI_V7 to be
enabled. These options inherit a dependency from an enclosing menu,
that requires ARCH_MULTIPLATFORM to be 'enabled'.
This is a contradiction and made this option also unavailable for
non-multiplatform configurations.

Since there are no selects on OMAP4_ERRATA_I688, which would ignore
dependencies, the code related to that option is dead and can be
removed.

This (logical) defect has been found with the undertaker tool.

OMAP4/5 has been (ab)using the gic_arch_extn to provide

BIG FAT WARNING: because the DTs were so far lying by not
exposing the WUGEN HW block, kernels with this patch applied
won't have any suspend-resume facility when booted with old DTs,
and old kernels with updated DTs won't even boot.

Converting it to stacked domains makes it slightly more

Unfortunately, as the DT bindings failed to acknowledge the

even though the access is defined as asynchronous, and no GPMC_CLK clock

for the GPMC clock, so it must be programmed to define the
correct WAITMONITORINGTIME delay.

DRA7x's ATL hwmod is one example for this since McASP can select ATL clock

trigger false warning from lockdep validator as it is dealing with classes

Linus Torvalds 18a8d49973 The clock framework changes for 3.20 contain the usual driver additions,
enhancements and fixes mostly for ARM32, ARM64, MIPS and Power-based
 devices. Additionaly the framework core underwent a bit of surgery with
 two major changes. The boundary between the clock core and clock
 providers (e.g clock drivers) is now more well defined with dedicated
 provider helper functions. struct clk no longer maps 1:1 with the
 hardware clock but is a true per-user cookie which helps us tracker
 users of hardware clocks and debug bad behavior. The second major change
 is the addition of rate constraints for clocks. Rate ranges are now
 supported which are analogous to the voltage ranges in the regulator
 framework. Unfortunately these changes to the core created some
 breakeage. We think we fixed it all up but for this reason there are
 lots of last minute commits trying to undo the damage.

     hardware clocks and debug bad behavior.

   - The addition of rate constraints for clocks.  Rate ranges are now
     supported which are analogous to the voltage ranges in the
     regulator framework.

  Unfortunately these changes to the core created some breakeage.  We
  think we fixed it all up but for this reason there are lots of last
  minute commits trying to undo the damage"

Uwe Kleine-König 444d2d33d8 ARM: make of_device_ids const
of_device_ids (i.e. compatible strings and the respective data) are not
supposed to change at runtime. All functions working with of_device_ids
provided by <linux/of.h> work with const of_device_ids. So mark the
non-const structs in arch/arm as const, too.

While at it also add some __initconst annotations.

Linus Torvalds 878ba61aa9 ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the
 platform maintainers hadn't separated cleanups from new developent in
 separate branches.
 
 Some of the larger things worth pointing out:
 
 - A large set of changes from Alexandre Belloni and Nicolas Ferre
   preparing at91 platforms for multiplatform and cleaning up quite a
   bit in the process.
 - Removal of CSR's "Marco" SoC platform that never made it out to the
   market. We love seeing these since it means the vendor published
   support before product was out, which is exactly what we want!
 
 New platforms this release are:
 
 - Conexant Digicolor (CX92755 SoC)
 - Hisilicon HiP01 SoC
 - CSR/sirf Atlas7 SoC
 - ST STiH418 SoC
 - Common code changes for Nvidia Tegra132 (64-bit SoC)
 
 We're seeing more and more platforms having a harder time labelling
 changes as cleanups vs new development -- which is a good sign that
 we've come quite far on the cleanup effort. So over time we might start
 combining the cleanup and new-development branches more.

The dummy clock in arch/arm/mach-omap2 is made redundant by the OMAP3+
clock data that migrated to drivers/clk.

An additional benefit to this clean-up is removing the references to
clk-private.h which will be removed.

Tomeu Vizoso 035a61c314 clk: Make clk API return per-user struct clk instances
Moves clock state to struct clk_core, but takes care to change as little API as
possible.

struct clk_hw still has a pointer to a struct clk, which is the
implementation's per-user clk instance, for backwards compatibility.

The struct clk that clk_get_parent() returns isn't owned by the caller, but by
the clock implementation, so the former shouldn't call clk_put() on it.

Because some boards in mach-omap2 still register clocks statically, their clock
registration had to be updated to take into account that the clock information
is stored in struct clk_core now.

Tony Lindgren 4d38bd1237 ARM: OMAP2+: Add dm816x hwmod support
Add minimal hwmod support that works at least on dm8168. This
is based on the code in the earlier TI CDP tree, and an earlier
patch by Aida Mynzhasova <aida.mynzhasova@skitlab.ru>.

I've set up things to work pretty much the same way as for

of clocks and clockdomains.

This patch adds required definitions and structures for clockdomain

new ti81xx_clockdomains_init() while early initialization of

Note that we now need to have 81xx in a separate CONFIG_SOC_TI81XX
block instead inside the ifdef block for omap3 to avoid make
randconfig build errors.

On DRA7 UART3 hwmod doesn't have this flag enabled, and atleast on
BeagleBoard-X15, where we use UART3 for console, boot fails with
DEBUG_LL enabled. Enable DEBUG_OMAP4UART3_FLAGS for UART3 hwmod.

For using DEBUG_LL, enable CONFIG_DEBUG_OMAP4UART3 in menuconfig.

We still have SND_OMAP_SOC_AM3517EVM depending on MACH_OMAP3517EVM,
so let's keep MACH_OMAP3517EVM Kconfig option around for a little
bit longer.

This removes the dependency between ARM SoC changes and the ASoC
changes, and allows the following three options for the driver:

1. Update the driver for device tree based booting

2. Initialize the driver with legacy platform data, then update
   the driver for device tree based booting

3. Just remove the driver if there are no audio users for
   3517-evm board

Marc Zyngier 0fb22a8fb7 ARM: OMAP: Work around hardcoded interrupts
Commit 9a1091ef00 ("irqchip: gic: Support hierarchy irq domain")
changed the GIC driver to use a non-legacy IRQ domain on DT
platforms. This patch assumes that DT-driven systems are getting
all of their interrupts from device tree.

Turns out that OMAP has quite a few hidden gems, and still uses
hardcoded interrupts despite having fairly complete DTs.

This patch attempts to work around these by offering a translation
method that can be called directly from the hwmod code, if present.
The same hack is sprinkled over PRCM and TWL.

It isn't pretty, but it seems to do the job without having to add
more hacks to the interrupt controller code.

Tested on OMAP4 (Panda-ES) and OMAP5 (UEVM5432).
