+ST Ericsson Nomadik pinmux controller
+
+Required properties:
+- compatible: "stericsson,nmk_pinctrl"
+- reg: Should contain the register physical address and length of the PRCMU.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+ST Ericsson's pin configuration nodes act as a container for an abitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as inputn output, pull up, pull down...
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Required subnode-properties:
+- ste,pins : An array of strings. Each string contains the name of a pin or
+    group.
+
+Optional subnode-properties:
+- ste,function: A string containing the name of the function to mux to the
+  pin or group.
+
+- ste,input:			no parameter, set pin in input with no pull mode.
+- ste,input_pull_up:		no parameter, set pin in input with pull up mode.
+- ste,input_pull_down:		no parameter, set pin in input with pull down mode.
+
+- ste,output:			integer, 0: output low, 1: output high, 2: output (value is not specified).
+- ste,sleep_mode:		integer, 0: sleep mode disable, 1: sleep mode enable.
+
+- ste,sleep_input:		no parameter, set pin in sleep input with no pull mode.
+- ste,sleep_input_pull_up:	no parameter, set pin in sleep input with pull up mode.
+- ste,sleep_input_pull_down:	no parameter, set pin in sleep input with pull down mode.
+
+- ste,sleep_output:		integer, 0: sleep output low, 1: sleep output high, 2: sleep output (value is not specified).
+
+- ste,sleep_wakeup:		interger, 0: disable sleep wakeup mode, 1: enable sleep wake up mode.
+- ste,sleep_gpio:		interger, 0: disable sleep gpio mode, 1: enable sleep gpio mode.
+
+- ste,sleep_pdis_mode:		integer, 0: pdis disabled, 1: pdis enable.
+
+
+Valid values for pin and group name are in Drivers/pinctrl/pinctrl-nomadik-db8500.c
