-Device-Tree bindings for Atmel's HLCDC (High-end LCD Controller) PWM driver
-
-The Atmel HLCDC PWM is subdevice of the HLCDC MFD device.
-See ../mfd/atmel-hlcdc.txt for more details.
-
-Required properties:
- - compatible: value should be one of the following:
- "atmel,hlcdc-pwm"
- - pinctr-names: the pin control state names. Should contain "default".
- - pinctrl-0: should contain the pinctrl states described by pinctrl
- default.
- - #pwm-cells: should be set to 3. This PWM chip use the default 3 cells
- bindings defined in pwm.yaml in this directory.
-
-Example:
-
- hlcdc: hlcdc at f0030000 {
- compatible = "atmel,sama5d3-hlcdc";
- reg = <0xf0030000 0x2000>;
- clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>;
- clock-names = "periph_clk","sys_clk", "slow_clk";
-
- hlcdc_pwm: hlcdc-pwm {
- compatible = "atmel,hlcdc-pwm";
- pinctrl-names = "default";
- pinctrl-0 = <&pinctrl_lcd_pwm>;
- #pwm-cells = <3>;
- };
- };
