Subject: [PATCH 6/7] pinctrl: abx500: update device tree bindings
After force converting the ABx500 bindings in the driver and
device tree sources, also update the binding documentation to
state that we are now using standard bindings.

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.
-
-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.
-
-- generic pin configuration option to use. Example :
-
- default_cfg {
- ste,pins = "GPIO1";
- bias-disable;
- };
-
-- ste,config: Handle of pin configuration node containing the generic
- pinconfig options to use, as described in pinctrl-bindings.txt in
- this directory. Example :
-
- pcfg_bias_disable: pcfg_bias_disable {
- bias-disable;
- };
-
- default_cfg {
- ste,pins = "GPIO1";
- ste.config = <&pcfg_bias_disable>;
- };
+ST Ericsson's pin configuration nodes use the generic pin multiplexing
+and pin configuration bindings, see pinctrl-bindings.txt
