1ST Ericsson abx500 pinmux controller
2
3Required properties:
4- compatible: "stericsson,ab8500-gpio",  "stericsson,ab8540-gpio",
5	      "stericsson,ab8505-gpio", "stericsson,ab9540-gpio",

7Please refer to pinctrl-bindings.txt in this directory for details of the
8common pinctrl bindings used by client devices, including the meaning of the
9phrase "pin configuration node".
10
11ST Ericsson's pin configuration nodes act as a container for an arbitrary number of
12subnodes. Each of these subnodes represents some desired configuration for a
13pin, a group, or a list of pins or groups. This configuration can include the
14mux function to select on those pin(s)/group(s), and various pin configuration
15parameters, such as input, output, pull up, pull down...
16
17The name of each subnode is not important; all subnodes should be enumerated
18and processed purely based on their content.
19
20Required subnode-properties:
21- ste,pins : An array of strings. Each string contains the name of a pin or
22    group.
23
24Optional subnode-properties:
25- ste,function: A string containing the name of the function to mux to the
26  pin or group.
27
28- generic pin configuration option to use. Example :
29
30	default_cfg {
31		ste,pins = "GPIO1";
32		bias-disable;
33	};
34
35- ste,config: Handle of pin configuration node containing the generic
36  pinconfig options to use, as described in pinctrl-bindings.txt in
37  this directory. Example :
38
39	pcfg_bias_disable: pcfg_bias_disable {
40		bias-disable;
41	};
42
43	default_cfg {
44		ste,pins = "GPIO1";
45		ste.config = <&pcfg_bias_disable>;
46	};
