* 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>;
};
