   3 Required properties:
   4 - compatible: "stericsson,ab8500-gpio",  "stericsson,ab8540-gpio",
   5               "stericsson,ab8505-gpio", "stericsson,ab9540-gpio",

   7 Please refer to pinctrl-bindings.txt in this directory for details of the
   8 common pinctrl bindings used by client devices, including the meaning of the
   9 phrase "pin configuration node".
  10
  11 ST Ericsson's pin configuration nodes act as a container for an arbitrary number of
  12 subnodes. Each of these subnodes represents some desired configuration for a
  13 pin, a group, or a list of pins or groups. This configuration can include the
  14 mux function to select on those pin(s)/group(s), and various pin configuration
  15 parameters, such as input, output, pull up, pull down...
  16
  17 The name of each subnode is not important; all subnodes should be enumerated
  18 and processed purely based on their content.
  19
  20 Required subnode-properties:
  21 - ste,pins : An array of strings. Each string contains the name of a pin or
  22     group.
  23
  24 Optional 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         };
