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.

......@@ -8,42 +8,8 @@ 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.
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
