-Broadcom Kona PWM controller device tree bindings
-
-This controller has 6 channels.
-
-Required Properties :
-- compatible: should contain "brcm,kona-pwm"
-- reg: physical base address and length of the controller's registers
-- clocks: phandle + clock specifier pair for the external clock
-- #pwm-cells: Should be 3. See pwm.yaml in this directory for a
- description of the cells format.
-
-Refer to clocks/clock-bindings.txt for generic clock consumer properties.
-
-Example:
-
-pwm: pwm@3e01a000 {
- compatible = "brcm,bcm11351-pwm", "brcm,kona-pwm";
- reg = <0x3e01a000 0xc4>;
- clocks = <&pwm_clk>;
- #pwm-cells = <3>;
