-ZTE ZX PWM controller
-
-Required properties:
- - compatible: Should be "zte,zx296718-pwm".
- - reg: Physical base address and length of the controller's registers.
- - clocks : The phandle and specifier referencing the controller's clocks.
- - clock-names: "pclk" for PCLK, "wclk" for WCLK to the PWM controller. The
- PCLK is for register access, while WCLK is the reference clock for
- calculating period and duty cycles.
- - #pwm-cells: Should be 3. See pwm.yaml in this directory for a description of
- the cells format.
-
-Example:
-
- pwm: pwm@1439000 {
- compatible = "zte,zx296718-pwm";
- reg = <0x1439000 0x1000>;
- clocks = <&lsp1crm LSP1_PWM_PCLK>,
- <&lsp1crm LSP1_PWM_WCLK>;
- clock-names = "pclk", "wclk";
- #pwm-cells = <3>;
- };
