Hisilicon Hi655x Power Management Integrated Circuit (PMIC) |
|
|
|
The hardware layout for access PMIC Hi655x from AP SoC Hi6220. |
|
Between PMIC Hi655x and Hi6220, the physical signal channel is SSI. |
|
We can use memory-mapped I/O to communicate. |
|

|
Required properties: |
|
- compatible: Should be "hisilicon,hi655x-pmic". |
|
- reg: Base address of PMIC on Hi6220 SoC. |
|
- interrupt-controller: Hi655x has internal IRQs (has own IRQ domain). |
|
- pmic-gpios: The GPIO used by PMIC IRQ. |
|
- #clock-cells: From common clock binding; shall be set to 0 |
|
|
|
Optional properties: |
|
- clock-output-names: From common clock binding to override the |
|
default output clock name |
|
|
|
Example: |
|
pmic: pmic@f8000000 { |
|
compatible = "hisilicon,hi655x-pmic"; |
|
reg = <0x0 0xf8000000 0x0 0x1000>; |
|
interrupt-controller; |
|
#interrupt-cells = <2>; |
|
pmic-gpios = <&gpio1 2 GPIO_ACTIVE_HIGH>; |
|
#clock-cells = <0>; |
|
}
