| 2 | |
| 3 | The Atmel HLCDC PWM is subdevice of the HLCDC MFD device. |
| 4 | See ../mfd/atmel-hlcdc.txt for more details. |
| 5 | |
| 6 | Required properties: |
| 7 | - compatible: value should be one of the following: |
| 8 | "atmel,hlcdc-pwm" |
| 9 | - pinctr-names: the pin control state names. Should contain "default". |
| 10 | - pinctrl-0: should contain the pinctrl states described by pinctrl |
| 11 | default. |
| 12 | - #pwm-cells: should be set to 3. This PWM chip use the default 3 cells |
| 13 | bindings defined in pwm.yaml in this directory. |
| 14 | |
| 15 | Example: |
| 16 | |
| 17 | hlcdc: hlcdc@f0030000 { |
| 18 | compatible = "atmel,sama5d3-hlcdc"; |
| 19 | reg = <0xf0030000 0x2000>; |
| 20 | clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>; |
| 21 | clock-names = "periph_clk","sys_clk", "slow_clk"; |
| 22 | |
| 23 | hlcdc_pwm: hlcdc-pwm { |
| 24 | compatible = "atmel,hlcdc-pwm"; |
| 25 | pinctrl-names = "default"; |
| 26 | pinctrl-0 = <&pinctrl_lcd_pwm>; |
| 27 | #pwm-cells = <3>; |
| 28 | }; |
| 29 | }; |
