1 Device-Tree bindings for Atmel's HLCDC (High LCD Controller) DRM driver 2 3 The Atmel HLCDC Display Controller 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 "atmel,hlcdc-display-controller" 8 - pinctrl-names: the pin control state names. Should contain "default". 9 - pinctrl-0: should contain the default pinctrl states. 10 - #address-cells: should be set to 1. 11 - #size-cells: should be set to 0. 12 13 Required children nodes: 14 Children nodes are encoding available output ports and their connections 15 to external devices using the OF graph reprensentation (see ../graph.txt). 16 At least one port node is required. 17 18 Example: 19 20 hlcdc: hlcdc@f0030000 { 21 compatible = "atmel,sama5d3-hlcdc"; 22 reg = <0xf0030000 0x2000>; 23 interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>; 24 clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>; 25 clock-names = "periph_clk","sys_clk", "slow_clk"; 26 status = "disabled"; 27 28 hlcdc-display-controller { 29 compatible = "atmel,hlcdc-display-controller"; 30 pinctrl-names = "default"; 31 pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb888>; 32 #address-cells = <1>; 33 #size-cells = <0>; 34 35 port@0 { 36 #address-cells = <1>; 37 #size-cells = <0>; 38 reg = <0>; 39 40 hlcdc_panel_output: endpoint@0 { 41 reg = <0>; 42 remote-endpoint = <&panel_input>; 43 }; 44 }; 45 }; 46 47 hlcdc_pwm: hlcdc-pwm { 48 compatible = "atmel,hlcdc-pwm"; 49 pinctrl-names = "default"; 50 pinctrl-0 = <&pinctrl_lcd_pwm>; 51 #pwm-cells = <3>; 52 }; 53 };
