-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

+When the pm_power_off is called, the gpio is configured as an output,

+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.

+CSR SiRFprimaII pinmux controller
+
+Required properties:
+- compatible : "sirf,prima2-pinctrl"
+- reg : Address range of the pinctrl registers
+- interrupts : Interrupts used by every GPIO group
+- gpio-controller : Indicates this device is a GPIO controller
+- interrupt-controller : Marks the device node as an interrupt controller
+Optional properties:
+- sirf,pullups : if n-th bit of m-th bank is set, set a pullup on GPIO-n of bank m
+- sirf,pulldowns : if n-th bit of m-th bank is set, set a pulldown on GPIO-n of bank m
+
+Please refer to pinctrl-bindings.txt in this directory for details of the common
+pinctrl bindings used by client devices.
+
+SiRFprimaII's pinmux nodes act as a container for an abitrary number of subnodes.
+Each of these subnodes represents some desired configuration for a group of pins.
+
+Required subnode-properties:
+- sirf,pins : An array of strings. Each string contains the name of a group.
+- sirf,function: A string containing the name of the function to mux to the
+ group.
+
+ Valid values for group and function names can be found from looking at the
+ group and function arrays in driver files:
+ drivers/pinctrl/pinctrl-sirf.c
+
+For example, pinctrl might have subnodes like the following:
+ uart2_pins_a: uart2@0 {
+ uart {
+ sirf,pins = "uart2grp";
+ sirf,function = "uart2";
+ };
+ };
+ uart2_noflow_pins_a: uart2@1 {
+ uart {
+ sirf,pins = "uart2_nostreamctrlgrp";
+ sirf,function = "uart2_nostreamctrl";
+ };
+ };
+
+For a specific board, if it wants to use uart2 without hardware flow control,
+it can add the following to its board-specific .dts file.
+uart2: uart@0xb0070000 {
+ pinctrl-names = "default";
+ pinctrl-0 = <&uart2_noflow_pins_a>;
+}
