Merge tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "People are back from the holiday breaks, and it shows. Here are a bunch of fixes for a number of platforms: - A couple of small fixes for Nomadik - A larger set of changes for kirkwood/mvebu - uart driver selection, dt clocks, gpio-poweroff fixups, a few __init annotation fixes and some error handling improvement in their xor dma driver. - i.MX had a couple of minor fixes (and a critical one for flexcan2 clock setup) - MXS has a small board fix and a framebuffer bugfix - A set of fixes for Samsung Exynos, fixing default bootargs and some Exynos5440 clock issues - A set of OMAP changes including PM fixes and a few sparse warning fixups All in all a bit more positive code delta than we'd ideally want to see here, mostly from the OMAP PM changes, but nothing overly crazy." * tag 'fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (44 commits) ARM: clps711x: Fix bad merge of clockevents setup ARM: highbank: save and restore L2 cache and GIC on suspend ARM: highbank: add a power request clear ARM: highbank: fix secondary boot and hotplug ARM: highbank: fix typos with hignbank in power request functions ARM: dts: fix highbank cpu mpidr values ARM: dts: add device_type prop to cpu nodes on Calxeda platforms ARM: mx5: Fix MX53 flexcan2 clock ARM: OMAP2+: am33xx-hwmod: Fix wrongly terminated am33xx_usbss_mpu_irqs array pinctrl: mvebu: make pdma clock on dove mandatory ARM: Dove: Add pinctrl clock to DT dma: mv_xor: fix error handling for clocks dma: mv_xor: fix error handling of mv_xor_channel_add() arm: mvebu: Add missing ; for cpu node. arm: mvebu: Armada XP MV78230 has only three Ethernet interfaces arm: mvebu: Armada XP MV78230 has two cores, not one clk: mvebu: Remove inappropriate __init tagging ARM: Kirkwood: Use fixed-regulator instead of board gpio call ARM: Kirkwood: Fix missing sdio clock ARM: Kirkwood: Switch TWSI1 of 88f6282 to DT clock providers ...

-GPIO line that should be set high/low to power off a device
+Driver a GPIO line that can be used to turn the power off.

+The driver supports both level triggered and edge triggered power off.
+At driver load time, the driver will request the given gpio line and
+install a pm_power_off handler. If the optional properties 'input' is
+not found, the GPIO line will be driven in the inactive
+state. Otherwise its configured as an input.
+
+When the pm_power_off is called, the gpio is configured as an output,
+and drive active, so triggering a level triggered power off
+condition. This will also cause an inactive->active edge condition, so
+triggering positive edge triggered power off. After a delay of 100ms,
+the GPIO is set to inactive, thus causing an active->inactive edge,
+triggering negative edge triggered power off. After another 100ms
+delay the GPIO is driver active again. If the power is still on and
+the CPU still running after a 3000ms delay, a WARN_ON(1) is emitted.
