Merge branch 'kbuild/rc-fixes' into kbuild/kconfig
There is one kconfig fix in the rc-fixes branch that I forgot to submit for 3.8, so let's add it to the kconfig branch for 3.9-rc1.

+GPIO line that should be set high/low to power off a device
+
+Required properties:
+- compatible : should be "gpio-poweroff".
+- gpios : The GPIO to set high/low, see "gpios property" in
+ Documentation/devicetree/bindings/gpio/gpio.txt. If the pin should be
+ low to power down the board set it to "Active Low", otherwise set
+ gpio to "Active High".
+
+Optional properties:
+- input : Initially configure the GPIO line as an input. Only reconfigure
+ it to an output when the pm_power_off function is called. If this optional
+ property is not specified, the GPIO is initialized as an output in its
+ inactive state.
+
+
+Examples:
+
+gpio-poweroff {
+ compatible = "gpio-poweroff";
+ gpios = <&gpio 4 0>; /* GPIO 4 Active Low */
+};
