* SM5502 MUIC (Micro-USB Interface Controller) device



The Silicon Mitus SM5502 is a MUIC (Micro-USB Interface Controller) device

which can detect the state of external accessory when external accessory is

attached or detached and button is pressed or released. It is interfaced to

the host controller using an I2C interface.



Required properties:

- compatible: Should be "siliconmitus,sm5502-muic"

- reg: Specifies the I2C slave address of the MUIC block. It should be 0x25

- interrupt-parent: Specifies the phandle of the interrupt controller to which

  the interrupts from sm5502 are delivered to.

- interrupts: Interrupt specifiers for detection interrupt sources.



Example:



	sm5502@25 {

		compatible = "siliconmitus,sm5502-muic";

		interrupt-parent = <&gpx1>;

		interrupts = <5 0>;

		reg = <0x25>;

	};
