      This is a part of device tree bindings for Samsung S3C/S5P/Exynos SoC pin
      controller.
    
      Pins configuration for Samsung S3C/S5P/Exynos SoC pin controller.
    
      The values used for config properties should be derived from the hardware
      manual and these values are programmed as-is into the pin pull up/down and
      driver strength register of the pin-controller.
      See also include/dt-bindings/pinctrl/samsung.h with useful constants.
    
      See also Documentation/devicetree/bindings/pinctrl/samsung,pinctrl.yaml for
      additional information and example.

        description: |
          List of pins to configure. For initial and sleep states, the maximum
          number is one pin. In other cases there is no upper limit.
    
          The pins should use lowercase names matching hardware manual, e.g. for
          GPA0 bank: gpa0-0, gpa0-1, gpa0-2.

      samsung,pin-function:
        description: |
          The pin function selection that should be applied on the pins listed in the
          child node is specified using the "samsung,pin-function" property. The value
          of this property that should be applied to each of the pins listed in the
          "samsung,pins" property should be picked from the hardware manual of the SoC
          for the specified pin group. This property is optional in the child node if
          no specific function selection is desired for the pins listed in the child
          node. The value of this property is used as-is to program the pin-controller
          function selector register of the pin-bank.
