Merge tag 'dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC device tree conversions and enablement from Olof Johansson:
"Continued device tree conversion and enablement across a number of
platforms; Kirkwood, tegra, i.MX, Exynos, zynq and a couple of other
smaller series as well.
ux500 has seen continued conversion for platforms. Several platforms
have seen pinctrl-via-devicetree conversions for simpler
multiplatform. Tegra is adding data for new devices/drivers, and
Exynos has a bunch of new bindings and devices added as well.
So, pretty much the same progression in the right direction as the
last few releases."
Fix up conflicts as per Olof.

1 | GPIO line that should be set high/low to power off a device | ||
2 | |||
3 | Required properties: | ||
4 | - compatible : should be "gpio-poweroff". | ||
5 | - gpios : The GPIO to set high/low, see "gpios property" in | ||
6 | Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be | ||
7 | low to power down the board set it to "Active Low", otherwise set | ||
8 | gpio to "Active High". | ||

10 | Optional properties: | ||
11 | - input : Initially configure the GPIO line as an input. Only reconfigure | ||
12 | it to an output when the pm_power_off function is called. If this optional | ||
13 | property is not specified, the GPIO is initialized as an output in its | ||
