1 Device-Tree bindings for Atmel's HLCDC (High LCD Controller) DRM driver
3 The Atmel HLCDC Display Controller is subdevice of the HLCDC MFD device.
4 See ../../mfd/atmel-hlcdc.txt for more details.
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.
13 Required children nodes:
14 Children nodes are encoding available output ports and their connections
15 to external devices using the OF graph representation (see ../graph.txt).
16 At least one port node is required.
18 Optional properties in grandchild nodes:
19 Any endpoint grandchild node may specify a desired video interface
20 according to ../../media/video-interfaces.txt, specifically
21 - bus-width: recognized values are <12>, <16>, <18> and <24>, and
22 override any output mode selection heuristic, forcing "rgb444",
23 "rgb565", "rgb666" and "rgb888" respectively.

61 Example 2: With a video interface override to force rgb565; as above
62 but with these changes/additions:
65 hlcdc-display-controller {
66 pinctrl-names = "default";
67 pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb565>;
70 hlcdc_panel_output: endpoint@0 {
