|  | 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.txt 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>; | 
|  | }; |
