af6ba9d2d6 dts changes for omap variants for v5.4
Remove regulator-boot-off properties that we never had in the mainline
 kernel so they won't do anything. We add stdout-path for gta04, and
 make am335x-boneblue use am335x-osd335x-common.dtsi file.

a3a2902fb8 SoC changes for omap variants for v5.4
The first change moves platform-specific asm-offsets.h to arch/arm/mach-omap2
 to fix iessu with parallel build with CONFIG_IKHEADERS, and the second change
 removes a useless kfree.
 
 Note that the first change causes a trivial merge conflict with the iommu
 changes for arch/arm/mach-omap2/Makefile.

Merge tag 'omap-for-v5.4/soc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/soc

SoC changes for omap variants for v5.4

The first change moves platform-specific asm-offsets.h to arch/arm/mach-omap2
to fix iessu with parallel build with CONFIG_IKHEADERS, and the second change
removes a useless kfree.

Note that the first change causes a trivial merge conflict with the iommu
changes for arch/arm/mach-omap2/Makefile.

Maxim 77802 PMIC is a main PMIC for the following Exynos5 based boards:
Odroid XU, Chromebook Pit and Chromebook Pi. Driver for its voltage
regulator is needed very early during boot to properly instantiate SD/MMC
devices and mount rootfs, so change that driver to be compiled-in.

5b0eeeaa37 ARM: dts: exynos: Mark LDO10 as always-on on Peach Pit/Pi Chromebooks
Commit aff138bf8e37 ("ARM: dts: exynos: Add TMU nodes regulator supply
for Peach boards") assigned LDO10 to Exynos Thermal Measurement Unit,
but it turned out that it supplies also some other critical parts and
board freezes/crashes when it is turned off.

The mentioned commit made Exynos TMU a consumer of that regulator and in
typical case Exynos TMU driver keeps it enabled from early boot. However
there are such configurations (example is multi_v7_defconfig), in which
some of the regulators are compiled as modules and are not available
from early boot. In such case it may happen that LDO10 is turned off by
regulator core, because it has no consumers yet (in this case consumer
drivers cannot get it, because the supply regulators for it are not yet
available). This in turn causes the board to crash. This patch restores
'always-on' property for the LDO10 regulator.

 - vf610-bk4 fails to detect its flash due to an incorrect description
 - meson-g12a USB phy configuration fails
 - meson-g12b reboot should not power off the SD card
 - Some corrections for apparently harmless differences from the
   documentation.
 
 Regression fixes:
 - ams-delta FIQ interrupts broke in 5.3
 - TI am3/am4 mmc controllers broke in 5.2
 
 The logic_pio driver (used on some Huawei ARM servers) needs a few
 bug fixes for reliability.

9e8e8912b0 irqchip/mmp: Mask off interrupts from other cores
On mmp3, there's an extra set of ICU registers (ICU2) that handle
interrupts on the extra cores.  When masking off interrupts on MP1,
these should be masked as well.

We add a new interrupt controller via device tree to identify when we're
looking at an mmp3 machine via compatible field of "marvell,mmp3-intc".

[lkundrak@v3.sk: Changed "mrvl,mmp3-intc" compatible strings to
"marvell,mmp3-intc". Tidied up the subject line a bit.]

  compatibility twice.
- Drop an superfluous call to irq_set_default_host()

419e2f1838 dma-mapping: remove arch_dma_mmap_pgprot
arch_dma_mmap_pgprot is used for two things:

 1) to override the "normal" uncached page attributes for mapping
    memory coherent to devices that can't snoop the CPU caches
 2) to provide the special DMA_ATTR_WRITE_COMBINE semantics on older
    arm systems and some mips platforms

Replace one with the pgprot_dmacoherent macro that is already provided
by arm and much simpler to use, and lift the DMA_ATTR_WRITE_COMBINE
handling to common code with an explicit arch opt-in.

The stackframe setup when compiled with clang is different.
Since the stack unwinder expects the gcc stackframe setup it

pfn_valid can be wrong when parsing a invalid pfn whose phys address
exceeds BITS_PER_LONG as the MSB will be trimed when shifted.

The issue originally arise from bellowing call stack, which corresponding to
an access of the /proc/kpageflags from userspace with a invalid pfn parameter
and leads to kernel panic.

b786a05f6c ARM: dts: ux500: Update thermal zone
After moving the DB8500 thermal driver to use device tree
we define the default thermal zone for the Ux500 in the
device tree replacing the oldstyle hardcoded trigger
points.

This default thermal zone utilizes the cpufreq driver
(using the generic OF cpufreq back-end) as a passive
cooling device, and defines a critical trip point when
the temperature goes above 85 degrees celsius which will
(hopefully) make the system shut down if the temperature
cannot be controlled.

This default policy can later be augmented for specific
subdevices if these have tighter temperature conditions.

After this patch we get:

/sys/class/thermal/thermal_zone0 (CPU thermal zone)
This reports the rough temperature and trip points
from the thermal zone in the device tree.

By executing two yes > /dev/null & jobs fully utilizing
the two CPU cores we can notice the temperature climbing
in the thermal zone in response and falling when we kill
the jobs.

/syc/class/thermal/cooling_device0 (cpufreq cooling)
this reports all 4 available cpufreq frequencies as
states.

tree data only and drop the custom "ti,hwmods" property.

We have already added the related device tree data earlier, and have
already dropped the platform data. But we have been still dynamically
allocating the platform data based on "ti,hwmods" property. With recent
ti-sysc driver changes this is no longer needed.
