+ST Ericsson Nomadik pinmux controller
+
+Required properties:
+- compatible: "stericsson,db8500-pinctrl", "stericsson,db8540-pinctrl",
+              "stericsson,stn8815-pinctrl"
+- nomadik-gpio-chips: array of phandles to the corresponding GPIO chips
+              (these have the register ranges used by the pin controller).
+- prcm: phandle to the PRCMU managing the back end of this pin controller
+
+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 arbitrary 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 input, 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. The subnodes use the generic
+pin multiplexing node layout from the standard pin control bindings
+(see pinctrl-bindings.txt):
+
+Required pin multiplexing subnode properties:
+- function: A string containing the name of the function to mux to the
+  pin or group.
+- groups : An array of strings. Each string contains the name of a pin
+  group that will be combined with the function to form a multiplexing
+  set-up.
+
+Required pin configuration subnode properties:
+- pins: A string array describing the pins affected by the configuration
+  in the node.
+- ste,config: Handle of pin configuration node
+  (e.g. ste,config = <&slpm_in_wkup_pdis>)
+
+- ste,input : <0/1/2>
+	0: input with no pull
+	1: input with pull up,
+	2: input with pull down,
+
+- ste,output: <0/1/2>
+	0: output low,
+	1: output high,
+	2: output (value is not specified).
+
+- ste,sleep: <0/1>
+	0: sleep mode disable,
+	1: sleep mode enable.
+
+- ste,sleep-input: <0/1/2/3>
+	0: sleep input with no pull,
+	1: sleep input with pull up,
+	2: sleep input with pull down.
+	3: sleep input and keep last input configuration (no pull, pull up or pull down).
+
+- ste,sleep-output: <0/1/2>
+	0: sleep output low,
+	1: sleep output high,
+	2: sleep output (value is not specified).
+
+- ste,sleep-gpio: <0/1>
+	0: disable sleep gpio mode,
+	1: enable sleep gpio mode.
+
+- ste,sleep-wakeup: <0/1>
+	0: wake-up detection enabled,
+	1: wake-up detection disabled.
+
+- ste,sleep-pull-disable: <0/1>
+	0: GPIO pull-up or pull-down resistor is enabled, when pin is an input,
+	1: GPIO pull-up and pull-down resistor are disabled.
