* 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>;
|
|
};
