ST Ericsson abx500 pinmux controller
|
|
|
|
Required properties:
|
|
- compatible: "stericsson,ab8500-gpio", "stericsson,ab8540-gpio",
|
|
"stericsson,ab8505-gpio", "stericsson,ab9540-gpio",
|
|
|
|
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>;
|
|
};
|
|
|
|

|
|
|
|

|
|
