d9bfc86dc6 ARM: add mach-asm9260
it is low cost (?) SoC targeted for market in China and India which
trying to compete with AT91SAM9G25.

Here is some info:
http://www.alphascale.com/index.asp?ics/615.html

One of products:
http://www.aliexpress.com/store/product/2014-hot-sales-FREE-SHIPPING-new-Purple-core-ARM9-development-board-ASM9260T-SDRAM-power-line/433637_1931495721.html

In some cases this SoC looks similar to iMX23/iMX28. But currently it makes no
sense to merge mach code of this devices. Especially because most differences
are already collected mach-mxs folder.

32e049ad79 The i.MX SoC update for 3.19:
- Update i.MX6 suspend code to check DDR instead of CPU type, as the
    difference we need to handle is between LPDDR2 and DDR3, not SoCs.
  - Set anatop properly for LPDDR2 in DSM mode
  - Add support for new SoC LS1021A which integrates dual Cortex-A7
  - Add ENET initialization for i.MX6SX platform
  - Add cpufreq support for i.MX53 platform
  - Add a SNVS based poweroff driver for i.MX6 platforms
  - Use ARM  Global Timer as clocksource on VF610
 
 Note: the change set is built on top of tag imx-fixes-3.18-2 to resolve
 a conflict on file arch/arm/mach-imx/clk-vf610.c.

cfd074ad86 ARM: imx: temporarily remove CONFIG_SOC_FSL from LS1021A
The newly introduced LS1021A SoC selects CONFIG_SOC_FSL, which
is originally symbol used for the PowerPC based platforms
and guards lots of code that does not build on ARM.

This breaks allmodconfig, so let's remove it for now, until
either all those drivers are fixed or they use a dependency
on IMX instead.

a41820d690 ARM: imx: clk-vf610: get input clocks from assigned clocks
With the clock assignment device tree changes, the clocks get
initialized properly but the search for those clocks fails with
errors:

[    0.000000] i.MX clk 4: register failed with -17
[    0.000000] i.MX clk 5: register failed with -17

This is because the module can't find those clocks anymore, and
tries to initialize fixed clocks with the same name.

Get the clock modules input clocks from the assigned clocks by
default by using of_clk_get_by_name(). If this function returns
not a valid clock, fall back to the old behaviour and search the
input clock from the device tree's /clocks/$name node.

Merge tag 'for-v3.19/omap-b2' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.19/soc

Several more OMAP patches targeted for v3.19. They include:

- OMAP4/5: DSS hwmod cleanup patches from Tomi Valkeinen.
- DRA7xx: hwmod data support for UARTs 7 through 10.
- AM43xx: hwmod data support for the onboard ADC.

Basic build, boot, and PM test reports are here:

http://www.pwsan.com/omap/testlogs/omap-b-for-v3.19/20141121110550/

Note that I cannot test the DRA7xx or AM43xx patches, since I do not have
these boards.

d1180f69b8 ARM: OMAP2+: hwmod: AM43x: add hwmod support for ADC on AM43xx
This patch adds hwmod support for ADC on AM43xx. Since clockdomain
and offsets of adc_tsc are different from AM33xx, ADC data has been
directly added to AM43xx hwmod file.

c645a598f9 ARM: EXYNOS: Call regulator core suspend prepare and finish functions
The regulator framework has a set of helpers functions to be used when
the system is entering and leaving from suspend but these are not called
on Exynos platforms. This means that the .set_suspend_* function handlers
defined by regulator drivers are not called when the system is suspended.

This patch modifies Exynos Power Management Unit (PMU) initialization
implementation in following way:

- Added platform driver support for Exynos PMU IP.
- Added platform struct exynos_pmu_data to hold platform specific data.
- For each SoC's PMU support now we can add platform data and statically
  bind PMU configuration and SoC specific initialization function.
- Separate each SoC's PMU initialization function and make it as part of
  platform data.
- It also removes uses of soc_is_exynosXYZ().

e6131fa383 ARM: debug: move StrongARM debug include to arch/arm/include/debug
StrongARM debug-macro.S is quite standalone thing, depending only on
register mappings. Move it to proper place and add Kconfig entry.

omap4 and later, and to fix clock DPLL fixes by adding determine_rate

c830343a88 arm: pxa: pxa for v3.19
Hello Arnd, Kevin, Olof,
 
 This is a very quiet release, featuring a small cleanup, a tosa change
 on its charger driver, and support for pxa device-tree based pxa27x
 boards.
 
 The device-tree part will only be fully activated once clocks support
 is fully operation in the common clock framework.
