| 2 | |
| 3 | Required properties: |
| 4 | - compatible: value should be one of the following: |
| 5 | "atmel,at91sam9n12-hlcdc" |
| 6 | "atmel,at91sam9x5-hlcdc" |
| 7 | "atmel,sama5d2-hlcdc" |
| 8 | "atmel,sama5d3-hlcdc" |
| 9 | "atmel,sama5d4-hlcdc" |
| 10 | "microchip,sam9x60-hlcdc" |
| 11 | "microchip,sam9x75-xlcdc" |
| 12 | - reg: base address and size of the HLCDC device registers. |
| 13 | - clock-names: the name of the 3 clocks requested by the HLCDC device. |
| 14 | Should contain "periph_clk", "sys_clk" and "slow_clk". |
| 15 | - clocks: should contain the 3 clocks requested by the HLCDC device. |
| 16 | - interrupts: should contain the description of the HLCDC interrupt line |
| 17 | |
| 18 | The HLCDC IP exposes two subdevices: |
| 19 | - a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt |
| 20 | - a Display Controller: see ../display/atmel/hlcdc-dc.txt |
| 21 | |
| 22 | Example: |
| 23 | |
| 24 | hlcdc: hlcdc@f0030000 { |
| 25 | compatible = "atmel,sama5d3-hlcdc"; |
| 26 | reg = <0xf0030000 0x2000>; |
| 27 | clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>; |
| 28 | clock-names = "periph_clk","sys_clk", "slow_clk"; |
| 29 | interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>; |
| 30 | |
| 31 | hlcdc-display-controller { |
| 32 | compatible = "atmel,hlcdc-display-controller"; |
| 33 | pinctrl-names = "default"; |
| 34 | pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb888>; |
| 35 | #address-cells = <1>; |
| 36 | #size-cells = <0>; |
| 37 | |
| 38 | port@0 { |
| 39 | #address-cells = <1>; |
| 40 | #size-cells = <0>; |
| 41 | reg = <0>; |
| 42 | |
| 43 | hlcdc_panel_output: endpoint@0 { |
| 44 | reg = <0>; |
| 45 | remote-endpoint = <&panel_input>; |
| 46 | }; |
| 47 | }; |
| 48 | }; |
| 49 | |
| 50 | hlcdc_pwm: hlcdc-pwm { |
| 51 | compatible = "atmel,hlcdc-pwm"; |
| 52 | pinctrl-names = "default"; |
| 53 | pinctrl-0 = <&pinctrl_lcd_pwm>; |
| 54 | #pwm-cells = <3>; |
| 55 | }; |
| 56 | }; |
