00e729c933 ARM: DT updates for v4.9
These are as usual a very large number of mostly boring updates to
 enable devices in existing machines, or to fix minor bugs.  Notably,
 an ongoing treewide effort to fix warnings caused by an update to the
 device tree compiler. These are enabled with "make W=1" at the moment
 but can hopefully become the default once all issues have been addressed.
 
 No new SoC platform is added this time around (Armada 395 and Orion
 mv88f5181 are slight variations of existing ones), but a significant
 number of new dts files are added, which I list by platform:
 
 - Allwinner: Empire Electronix M712 and iNet d978 Rev2 tablets;
 	Orange Pi PC Plus, Orange Pi 2, Orange Pi Plus 2E,
 	Orange Pi Lite, Olimex A33-Olinuxino, and Nano Pi Neo
 	single-board computers

8f899b4ed6 ARM: davinci: da850: Add ti-aemif lookup for clock matching
The davinci boards don't have their clocks in DT yet and getting a clock
will fail, unless registering them as clk_lookups. This registers the
aemif clock for the ti-aemif memory driver.

The current aemif lookup entry resolving to the same clock:
    'CLK(NULL,               "aemif",        &aemif_clk)'
is currently used by davinci_nand and remains for non-DT and backward
compatibility.

Currently the davinci boards only configure the AEMIF in case of non-DT
boot, via some code in mach-davinci.
This change will allow DT-based davinci platforms to do the same, via
the ti-aemif memory driver code.

44524a010a ARM: dts: da850: Add basic DTS for the LCDK
The LCDK is the successor to the late Hawkboard.
Among the differences are the flash (16bits vs 8bits) and some pins
(MMC, LEDs, buttons, some external connectors), however the main
components remain the same (eth. phy, audio codec, video decoder and
DAC) except for the main PMIC, different and hard-wired on the LCDK (the
LDOs and DCDCs are always on).
A DT-only boot with this addition gives functional UART, reboot via
watchdog, RTC, ethernet and MMC (I added the CD GPIO for the MMC
although davinci_mmc doesn't call the OF facilities of mmc core).

933b11aeed ARM: davinci: fix build break because of undeclared dm365_evm_snd_data
commit 6bce5efd44 ("ARM: davinci: remove unused davinci-i2s pdata")
removed all instances of davinci-i2s pdata. However, on DM365 EVM,
the same platform data is passed to the voicecodec present on that
device.

This causes build breakage when voicecodec support is enabled:

arch/arm/mach-davinci/board-dm365-evm.c:764:17: error: 'dm365_evm_snd_data' undeclared (first use in this function)

voicecodec driver does not use the platform data as well, and
it is safe to remove it.

f7df9be067 ARM: DT updates for v4.7
These are all the updates to device tree files for 32-bit platforms,
 which as usual makes up the bulk of the ARM SoC changes: 462 non-merge
 changesets, 450 files changed, 23340 insertions, 5216 deletions.
 
 The three platforms that are added with the "soc" branch are here as well,
 and we add some related machine files:
 
 - For Aspeed AST2400/AST2500, we get the evaluation platform and
   the Tyan Palmetto POWER8 mainboard that uses the AST2400 BMC
 - For Oxnas 810SE, the Western Digital "My Book World Edition"
   is added as the only platform at the moment.
 - For ARM MPS2, the AN385 (Cortex-M3) and AN399 (Cortex-M7)
   are supported
 
 On the ARM Realview development platform, we now support all machines
 with device tree, previously only the board files were supported, which
 in turn will likely be removed soon.
 
 Qualcomm IPQ4019 is the second generation ARM based "Internet Processor",
 following the IPQ806x that is used in many high-end WiFi routers. This one
 integrates two ath10k wifi radios that were previously on separate chips.

   - Boundary Devices i.MX6 Quad Plus Nitrogen6_MAX and
     SoloX Nitrogen6sx embedded boards
   - Technexion Pico i.MX6UL compute module
   - ZII VF610 Development Board
 
 - On Marvell embedded (mvebu, orion, kirkwood) platforms:
   - Linksys Viper (E4200v2 / EA4500) WiFi router
   - Buffalo Kurobox Pro NAS

9896c7b57e ARM: SoC platform updates for v4.7
We get support for three new 32-bit SoC platforms this time. The amount
 of changes in arch/arm for any of them is miniscule, as all the
 interesting code is in device driver subsystems (irqchip, clk, pinctrl,
 ...) these days. I'm listing them here, as the addition of the Kconfig
 statement is the main relevant milestone for a new platform. In each
 case, some drivers are are shared with existing platforms, while
 other drivers are added for v4.7 as well, or come in a later release.
 
 - The Aspeed platform is probably the most interesting one, this is
   what most whitebox servers use as their baseboard management
   controller. We get support for the very common ast2400 and ast2500
   SoCs. The OpenBMC project focuses on this chip, and the LWN
   article about their ELC 2016 presentation at
   https://lwn.net/Articles/683320/ triggered the submission, but the
   code comes from IBM's OpenPOWER team rather than the team at
   Facebook. There are still a lot more drivers that need to get added
   over time, and I hope both teams can work together on that.
 
 - OXNAS is an old platform for Network Attached Storage devices
   from Oxford Semiconductor. There are models with ARM10 (!) and
   ARM11MPCore cores, but for now, we only support the original ARM9
   based versions.
   The product lineup was subsequently part of PLX, Avago and now the
   new Broadcom Ltd. https://wiki.openwrt.org/doc/hardware/soc/soc.oxnas
   has some more information.
 
 - V2M-MPS2 is a prototyping platform from ARM for their Cortex-M
   cores and is related to the existing Realview / Versatile Express
   lineup, but without MMU. We now support various NOMMU platforms,
   so adding a new one is fairly straightforward.
   http://infocenter.arm.com/help/topic/com.arm.doc.100112_0100_03_en/
   has detailed information about the platform.
 
 Other noteworthy updates:
 
 - Work on LPC32xx has resumed, and Vladimir Zapolskiy and Sylvain Lemieux
   are now maintaining the platform. This is an older ARM9 based
   platform from NXP (not Freescale), but it remains in use in embedded
   markets.
 
 - Kevin Hilman is now co-maintaining the Amlogic Meson platform for both
   32-bit and 64-bit ARM, and started contributing some patches.
 
 - As is often the case, work on the OMAP platforms makes up the bulk of
   the actual SoC code changes in arch/arm, but there isn't a lot of
   that either.

f2b1e0f638 ARM: SoC cleanups and fixes for v4.7
Traditionally we've had two separate branches for cleanups and non-critical
 bug fixes, but both of these got smaller with each release and the differences
 are rather unclear now, so it seems more appropriate to have a combined
 branch.
 
 The most notably change is for OMAP, which gets a small rework to simplify
 handling of the AUXDATA mechanism used on machines that are not completely
 DT based yet, along with other work that is used as preparation for dropping
 the legacy board files.

04b9665b54 ARM: davinci: only use NVMEM when available
The davinci platform contains code that calls into the nvmem
subsystem, but that might be a loadable module, causing a
link error:

arch/arm/mach-davinci/built-in.o: In function `davinci_get_mac_addr':
:(.text+0x1088): undefined reference to `nvmem_device_read'
arch/arm/mach-davinci/built-in.o: In function `read_factory_config':
:(.text+0x214c): undefined reference to `nvmem_device_read'

Also, when NVMEM is completely disabled, the functions fail with
nonobvious error messages.

This ensures we only call the API functions when the code is actually
reachable from the board file, and otherwise prints a unique log
message.

The da850 family of processors has an async3 clock domain that can be
muxed to either pll0_sysclk2 or pll1_sysclk2. Now that the davinci clocks
have a set_parent callback, we can use this to control the async3 mux
instead of a stand-alone function.

This adds a new async3_clk and sets the appropriate child clocks. The
default is use to pll1_sysclk2 since it is not affected by processor
frequency scaling.

4d2b7d4cb4 ARM: 8532/1: uncompress: mark putc as inline
When CONFIG_DEBUG_ICEDCC is set, we don't use the platform
specific putc() function, but use icedcc_putc() instead, so
putc is unused and causes a compile time warning:

In file included from ../arch/arm/boot/compressed/misc.c:28:0:
arch/arm/mach-rpc/include/mach/uncompress.h:79:13: warning: 'putc' defined but not used [-Wunused-function]
arch/arm/mach-w90x900/include/mach/uncompress.h:30:13: warning: 'putc' defined but not used [-Wunused-function]

On most platforms, this does not happen, because putc is defined
as 'static inline' so the compiler will automatically drop it
when it's unused.

This changes the remaining seven platforms to behave the same way.

8e58041114 ARM: davinci: make I2C support optional
The davinci platform has tried to get support for the EEPROM right,
but failed to get a clean build so far. At the moment, we get
a warning whenever CONFIG_SYSFS is disabled, as that is needed by
EEPROM_AT24:

warning: (MACH_DAVINCI_EVM && MACH_SFFSDR && MACH_DAVINCI_DM6467_EVM && MACH_DAVINCI_DM365_EVM && MACH_DAVINCI_DA830_EVM && MACH_MITYOMAPL138 && MACH_MINI2440) selects EEPROM_AT24 which has unmet direct dependencies (I2C && SYSFS)

Kevin Hilman initially added the 'select' to ensure that EEPROM_AT24
is always enabled in machines that really want it for normal operation
(i.e. for reading the MAC address). This broke when I2C was disabled,
and Russell King followed up with another patch to select that as
well.

I now see that the SYSFS dependency is still missing, which leaves
us with three options:

a) add 'select SYSFS' in addition to the others
b) change AT24_EEPPROM to work without sysfs (should be possible)
c) remove all those selects again and get the files to build when
   I2C is disabled.

I would really hate to do a) because adding select statements that
hardwire user-selectable symbols is generally a bad idea. I first
tried b) but then ended up redoing the patch from scratch to approach
c), so we can also remove the other selects.

I checked that CONFIG_I2C is still enabled with davinci_all_defconfig,
so that does not have to change.

We already forbid that combination when AUTO_ZRELADDR is disabled,
for the same reason that the two have their RAM at different
physical addresses as seen from the CPU.

This does the same change for PATCH_PHYS_VIRT: if you disable
either of the options, Kconfig now enforces that you have to
pick one or the other SoC family.

When da8xx-dt.c is built with onlu DA830 support but not DA850

arch/arm/mach-davinci/da8xx-dt.c:28:20: warning: 'da8xx_init_irq' defined but not used [-Wunused-function]

 static struct of_dev_auxdata da850_auxdata_lookup[] __initdata = {

Obviously none of the file make sense for DA830, so we should not
even attempt this, so we can avoid the warning by ensuring it is
only built for 850, not 830.

6b5a12dbca 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.

  in through -rc.

   - MAINTAINERS updates to add a list for brcmstb and fix a typo
   - A handful of fixes for OMAP 81xx, a recently resurrected platform
     so these can't be considered real regressions and thus got queued.
   - A couple of other small fixes for scoop, sa1100 and davinci"

5bcd927233 ARM: davinci: fix a problematic usage of WARN()
WARN() takes a condition and a format string. The condition was
omitted. So I added it.

1b50b0c1ce ARM: davinci: only select WT cache if cache is enabled
The DA830 chip only works if the dcache is in writethrough mode,
but that produces a harmless Kconfig warning if the cache happens
to be disabled:

warning: (ARCH_DAVINCI_DA830) selects CPU_DCACHE_WRITETHROUGH which has unmet direct dependencies ((CPU_ARM740T || CPU_ARM920T || CPU_ARM922T || CPU_ARM925T || CPU_ARM926T || CPU_ARM940T || CPU_ARM946E || CPU_ARM1020 || CPU_FA526) && !CPU_DCACHE_DISABLE)

This makes the select conditional so we don't have to worry
about the warning in randconfig builds any more.

b5dcee225c [media] include/media: split I2C headers from V4L2 core
Currently, include/media is messy, as it contains both the V4L2 core
headers and some driver-specific headers on the same place. That makes
harder to identify what core headers should be documented and what
headers belong to I2C drivers that are included only by bridge/main
drivers that would require the functions provided by them.

Let's move those i2c specific files to its own subdirectory.

The files to move were produced via the following script:
	mkdir include/media/i2c
	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
	(cd include/media; for i in *.h; do n=`echo $i|sed s/.h$/.c/`; if [ -e ../../drivers/media/*/i2c/$n ]; then echo $i; git mv $i i2c/; fi; done)
	for i in include/media/*.h; do n=`basename $i`;  (for j in $(git grep -l $n); do dirname $j; done)|sort|uniq|grep -ve '^.$' > list; num=$(wc -l list|cut -d' ' -f1); if [ $num == 1 ]; then if [ "`grep i2c list`" != "" ]; then git mv $i include/media/i2c; fi; fi; done

And the references corrected via this script:
    MAIN_DIR="media/"
    PREV_DIR="media/"
    DIRS="i2c/"

    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

Merged Sakari Ailus patch that moves smiapp.h to include/media/i2c.

Currently we have one device created to handle all (maximum 2) eDMAs in the
system.
With this change all eDMA instance will have it's own device/driver.
This change is needed for further cleanups in the eDMA driver stack since
the one device/driver to handle all eDMAs in the system was not flexible
enough and prevents the upcoming work.
