Marvell Orion MPP controller

1-19

공통 binding과 사용법은 같은 directory의 `marvell,mvebu-pinctrl.txt`를 따릅니다.

필수 `compatible` 값은 `marvell,88f5181-pinctrl`, `marvell,88f5181l-pinctrl`, `marvell,88f5182-pinctrl`, `marvell,88f5281-pinctrl`입니다.

`reg`는 두 register 영역을 지정합니다. 첫 영역은 연속된 앞쪽 MPP register 두 개를, 두 번째 영역은 이들과 떨어져 있는 마지막 MPP register 하나를 설명합니다. 아래 표의 괄호 설명은 `marvell,function`에 쓰는 MPP 이름의 일부가 아닙니다.
