5.3 swappiness
Similar to /proc/sys/vm/swappiness, but affecting a hierarchy of groups only.
+Please note that unlike the global swappiness, memcg knob set to 0
+really prevents from any swapping even if there is a swap storage
+available. This might lead to memcg OOM killer if there are no file
+pages to reclaim.
Following cgroups' swappiness can't be changed.
- root cgroup (uses /proc/sys/vm/swappiness).

+GPIO controlled regulators
+
+Required properties:
+- compatible : Must be "regulator-gpio".
+- states : Selection of available voltages and GPIO configs.
+ if there are no states, then use a fixed regulator
+
+Optional properties:
+- enable-gpio : GPIO to use to enable/disable the regulator.
+- gpios : GPIO group used to control voltage.
+- startup-delay-us : Startup time in microseconds.
+- enable-active-high : Polarity of GPIO is active high (default is low).
+
+Any property defined as part of the core regulator binding defined in
+regulator.txt can also be used.
+
+Example:
+
+ mmciv: gpio-regulator {
+ compatible = "regulator-gpio";
+
+ regulator-name = "mmci-gpio-supply";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <2600000>;

+ enable-gpio = <&gpio0 23 0x4>;
+ gpios = <&gpio0 24 0x4
