    3 Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and
    4 ../interrupt-controller/interrupts.txt for generic information regarding
    5 pin controller, GPIO, and interrupt bindings.

    7 OXNAS 'pin configuration node' is a node of a group of pins which can be
    8 used for a specific device or function. This node represents configurations of
    9 pins, optional function, and optional mux related configuration.
   10 
   11 Required properties for pin controller node:
   12  - compatible: "oxsemi,ox810se-pinctrl" or "oxsemi,ox820-pinctrl"
   13  - oxsemi,sys-ctrl: a phandle to the system controller syscon node
   14 
   15 Required properties for pin configuration sub-nodes:
   16  - pins: List of pins to which the configuration applies.
   17 
   18 Optional properties for pin configuration sub-nodes:
   19 ----------------------------------------------------
   20  - function: Mux function for the specified pins.
   21  - bias-pull-up: Enable weak pull-up.
   22 
   23 Example:
   24 
   25 pinctrl: pinctrl {
   26         compatible = "oxsemi,ox810se-pinctrl";
   27 
   28         /* Regmap for sys registers */
   29         oxsemi,sys-ctrl = <&sys>;
   30 
   31         pinctrl_uart2: pinctrl_uart2 {
   32                 uart2a {
   33                         pins = "gpio31";
   34                         function = "fct3";
   35                 };
   36                 uart2b {
   37                         pins = "gpio32";
   38                         function = "fct3";
   39                 };
   40         };
   41 };
   42 
   43 uart2: serial@900000 {
   44         compatible = "ns16550a";
   45         reg = <0x900000 0x100000>;
   46         clocks = <&sysclk>;
   47         interrupts = <29>;
   48         reg-shift = <0>;
   49         fifo-size = <16>;
   50         reg-io-width = <1>;
   51         current-speed = <115200>;
   52         no-loopback-test;
   53         resets = <&reset 22>;
   54         pinctrl-names = "default";
   55         pinctrl-0 = <&pinctrl_uart2>;
   56 };
