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>;
};
