| 2 | * SM5502 MUIC (Micro-USB Interface Controller) device |
| 3 | |
| 4 | The Silicon Mitus SM5502 is a MUIC (Micro-USB Interface Controller) device |
| 5 | which can detect the state of external accessory when external accessory is |
| 6 | attached or detached and button is pressed or released. It is interfaced to |
| 7 | the host controller using an I2C interface. |
| 8 | |
| 9 | Required 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 | |
| 16 | Example: |
| 17 | |
| 18 | sm5502@25 { |
| 19 | compatible = "siliconmitus,sm5502-muic"; |
| 20 | interrupt-parent = <&gpx1>; |
| 21 | interrupts = <5 0>; |
| 22 | reg = <0x25>; |
| 23 | }; |
