1 2* SM5502 MUIC (Micro-USB Interface Controller) device 3 4The Silicon Mitus SM5502 is a MUIC (Micro-USB Interface Controller) device 5which can detect the state of external accessory when external accessory is 6attached or detached and button is pressed or released. It is interfaced to 7the host controller using an I2C interface. 8 9Required properties: 10- compatible: Should be "siliconmitus,sm5502-muic" 11- reg: Specifies the I2C slave address of the MUIC block. It should be 0x25 12- interrupt-parent: Specifies the phandle of the interrupt controller to which 13 the interrupts from sm5502 are delivered to. 14- interrupts: Interrupt specifiers for detection interrupt sources. 15 16Example: 17 18 sm5502@25 { 19 compatible = "siliconmitus,sm5502-muic"; 20 interrupt-parent = <&gpx1>; 21 interrupts = <5 0>; 22 reg = <0x25>; 23 }; 24
