* Multi purpose pin (MPP) configuration.

Required properties:

- pin-map : array of pin configurations. Each pin is defined by 2 cells,

respectively: <pin> <function>. Pins not specified in the pin-map property

are assumed to have default value of <function> = 0, which means GPIO.

- pin : pin number.

- function : function ID of the pin according to the assignment tables in

User Manual. Each pin can have many possible functions depending on the

MPP unit incarnation.

- pin-count: number of the physical MPP connections on the SOC (depending on

the model it can be 24-50, or possibly else in future devices).

Example:

mpp@10000 {

#pin-cells = <2>;

compatible = "mrvl,mpp";

reg = <0x10000 0x34>;

pin-count= <50>;

pin-map = <
