* STMicroelectronics STPMIC1 Power Management IC
|
|
|
|
Required properties:
|
|
- compatible: : "st,stpmic1"
|
|
- reg: : The I2C slave address for the STPMIC1 chip.
|
|
- interrupts: : The interrupt line the device is connected to.
|
|
- #interrupt-cells: : Should be 1.
|
|
- interrupt-controller: : Marks the device node as an interrupt controller.
|
|
Interrupt numbers are defined at
|
|
dt-bindings/mfd/st,stpmic1.h.
|
|
|
|
STPMIC1 consists in a varied group of sub-devices.
|
|
Each sub-device binding is be described in own documentation file.
