      1* Microchip PIC32 Pin Controller
      2
      3Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and
      4../interrupt-controller/interrupts.txt for generic information regarding
      5pin controller, GPIO, and interrupt bindings.

      7PIC32 'pin configuration node' is a node of a group of pins which can be
      8used for a specific device or function. This node represents configurations of
      9pins, optional function, and optional mux related configuration.
     10
     11Required properties for pin controller node:
     12 - compatible: "microchip,pic32mada-pinctrl"
     13 - reg: Address range of the pinctrl registers.
     14 - clocks: Clock specifier (see clock bindings for details)
     15
     16Required properties for pin configuration sub-nodes:
     17 - pins: List of pins to which the configuration applies.
     18
     19Optional properties for pin configuration sub-nodes:
     20----------------------------------------------------
     21 - function: Mux function for the specified pins.
     22 - bias-pull-up: Enable weak pull-up.
     23 - bias-pull-down: Enable weak pull-down.
     24 - input-enable: Set the pin as an input.
     25 - output-low: Set the pin as an output level low.
     26 - output-high: Set the pin as an output level high.
     27 - microchip,digital: Enable digital I/O.
     28 - microchip,analog: Enable analog I/O.
