Merge tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc 

Pull ARM SoC platform changes from Olof Johansson:
 "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"

Rockchip SRAM for pmu:
------------------------------
The sram of pmu is used to store the function of resume from maskrom(the 1st
level loader). This is a common use of the "pmu-sram" because it keeps power
even in low power states in the system.
Required node properties:
- compatible : should be "rockchip,rk3288-pmu-sram"
- reg : physical base address and the size of the registers window
Example:
sram@ff720000 {
compatible = "rockchip,rk3288-pmu-sram", "mmio-sram";
reg = <0xff720000 0x1000>;

Hardware-triggered thermal reset:
On Tegra30, Tegra114 and Tegra124, if the 'i2c-thermtrip' subnode exists,
hardware-triggered thermal reset will be enabled.
Required properties for hardware-triggered thermal reset (inside 'i2c-thermtrip'):
- nvidia,i2c-controller-id : ID of I2C controller to send poweroff command to. Valid values are
described in section 9.2.148 "APBDEV_PMC_SCRATCH53_0" of the
Tegra K1 Technical Reference Manual.
- nvidia,bus-addr : Bus address of the PMU on the I2C bus
- nvidia,reg-addr : I2C register address to write poweroff command to
- nvidia,reg-data : Poweroff command to write to PMU
Optional properties for hardware-triggered thermal reset (inside 'i2c-thermtrip'):
- nvidia,pinmux-id : Pinmux used by the hardware when issuing poweroff command.
Defaults to 0. Valid values are described in section 12.5.2
"Pinmux Support" of the Tegra4 Technical Reference Manual.
