    1 Pincontrol driver for RK805 Power management IC.
    2 
    3 RK805 has 2 pins which can be configured as GPIO output only.
    4 
    5 Please refer file <devicetree/bindings/pinctrl/pinctrl-bindings.txt>
    6 for details of the common pinctrl bindings used by client devices,
    7 including the meaning of the phrase "pin configuration node".
    8 
    9 Optional Pinmux properties:
   10 --------------------------
   11 Following properties are required if default setting of pins are required
   12 at boot.
   13 - pinctrl-names: A pinctrl state named per <pinctrl-bindings.txt>.
   14 - pinctrl[0...n]: Properties to contain the phandle for pinctrl states per
   15                 <pinctrl-bindings.txt>.
   16 
   17 The pin configurations are defined as child of the pinctrl states node. Each
   18 sub-node have following properties:
   19 
   20 Required properties:
   21 ------------------
   22 - #gpio-cells: Should be two. The first cell is the pin number and the
   23   second is the GPIO flags.
   24 
   25 - gpio-controller: Marks the device node as a GPIO controller.
   26 
   27 - pins: List of pins. Valid values of pins properties are: gpio0, gpio1.
   28 
   29 First 2 properties must be added in the RK805 PMIC node, documented in
   30 Documentation/devicetree/bindings/mfd/rockchip,rk808.yaml
   31 
   32 Optional properties:
   33 -------------------
   34 Following are optional properties defined as pinmux DT binding document
   35 <pinctrl-bindings.txt>. Absence of properties will leave the configuration
   36 on default.
   37         function,
   38         output-low,
   39         output-high.
   40 
   41 Valid values for function properties are: gpio.
   42 
   43 Theres is also not customised properties for any GPIO.
   44 
   45 Example:
   46 --------
   47 rk805: rk805@18 {
   48         compatible = "rockchip,rk805";
   49         ...
   50         gpio-controller;
   51         #gpio-cells = <2>;
   52 
   53         pinctrl-names = "default";
   54         pinctrl-0 = <&pmic_int_l>, <&rk805_default>;
   55 
   56         rk805_default: pinmux {
   57                 gpio01 {
   58                         pins = "gpio0", "gpio1";
   59                         function = "gpio";
   60                         output-high;
   61                 };
   62         };
   63 };
