Add PWM driver for the PWM controller found on HiSilicon BVT SoCs such as Hi3519V100, Hi3516CV300, etc. The PWM controller is primarily in charge of controlling the P-Iris lens.

Hisilicon PWM controller
|
|
|
|
Required properties:
|
|
-compatible: should contain one SoC specific compatible string
|
|
The SoC specific strings supported including:
|
|
"hisilicon,hi3516cv300-pwm"
|
|
"hisilicon,hi3519v100-pwm"
|
|
- reg: physical base address and length of the controller's registers.
|
|
- clocks: phandle and clock specifier of the PWM reference clock.
|
|
- resets: phandle and reset specifier for the PWM controller reset.
|
|
- #pwm-cells: Should be 3. See pwm.txt in this directory for a description of
|
|
the cells format.
|
|
|
|
Example:
|
|
pwm: pwm@12130000 {
|
|
compatible = "hisilicon,hi3516cv300-pwm";
|
|
reg = <0x12130000 0x10000>;
|
|
clocks = <&crg_ctrl HI3516CV300_PWM_CLK>;
|
|
resets = <&crg_ctrl 0x38 0>;
|
|
#pwm-cells = <3>;
|
|
};
