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
