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 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 */

};

Binding for dual-GPIO LED found on Network Space v2 (and parents).

Required properties:

- compatible: "lacie,ns2-leds".

Each LED is represented as a sub-node of the ns2-leds device.

Required sub-node properties:

- cmd-gpio: Command LED GPIO. See OF device-tree GPIO specification.

- slow-gpio: Slow LED GPIO. See OF device-tree GPIO specification.

Optional sub-node properties:

- label: Name for this LED. If omitted, the label is taken from the node name.

- linux,default-trigger: Trigger assigned to the LED.

Example:

ns2-leds {

	compatible = "lacie,ns2-leds";

	blue-sata {

		label = "ns2:blue:sata";

		slow-gpio = <&gpio0 29 0>;

		cmd-gpio = <&gpio0 30 0>;

	};

};

- compatible: "marvell,88f6180-pinctrl",

              "marvell,88f6190-pinctrl", "marvell,88f6192-pinctrl",

              "marvell,88f6281-pinctrl", "marvell,88f6282-pinctrl"

              "marvell,98dx4122-pinctrl"

This driver supports all kirkwood variants, i.e. 88f6180, 88f619x, and 88f628x.

It also support the 88f6281-based variant in the 98dx412x Bobcat SoCs.
