Board ID Device Binding
======================

The device tree node which describes GPIO to use as the Board ID
is as follows:

Required properties :
- compatible = "sony,board-id"
- valid-bit-num : Set the number of bits to enable
- bid-gpios : Set GPIO to use as the Board ID
    bid-gpios must be set to valid-bit-num

Example
=======

	board_id {
		compatible = "sony,board-id";
		valid-bit-num = <3>;
		bid-gpios = <&gpio2 5 GPIO_ACTIVE_HIGH>,
				<&gpio2 4 GPIO_ACTIVE_HIGH>,
				<&gpio1 15 GPIO_ACTIVE_HIGH>;
	};
