Rob Herring efdbd7345f dt-bindings: consolidate display related bindings
This is a quite large renaming to consolidate display related bindings
into a single "display" directory from various scattered locations of
video, drm, gpu, fb, mipi, and panel. The prior location was somewhat
based on the Linux driver location, but bindings should be independent
of that.

Device-Tree bindings for Atmel's HLCDC (High LCD Controller) MFD driver
Required properties:
- compatible: value should be one of the following:
"atmel,at91sam9n12-hlcdc"
"atmel,at91sam9x5-hlcdc"
"atmel,sama5d2-hlcdc"
"atmel,sama5d3-hlcdc"
"atmel,sama5d4-hlcdc"
- reg: base address and size of the HLCDC device registers.
- clock-names: the name of the 3 clocks requested by the HLCDC device.
Should contain "periph_clk", "sys_clk" and "slow_clk".
- clocks: should contain the 3 clocks requested by the HLCDC device.
- interrupts: should contain the description of the HLCDC interrupt line
The HLCDC IP exposes two subdevices:
- a PWM chip: see ../pwm/atmel-hlcdc-pwm.txt
- a Display Controller: see ../display/atmel-hlcdc-dc.txt
Example:
hlcdc: hlcdc@f0030000 {
compatible = "atmel,sama5d3-hlcdc";
reg = <0xf0030000 0x2000>;
clocks = <&lcdc_clk>, <&lcdck>, <&clk32k>;
clock-names = "periph_clk","sys_clk", "slow_clk";
interrupts = <36 IRQ_TYPE_LEVEL_HIGH 0>;
status = "disabled";
hlcdc-display-controller {
compatible = "atmel,hlcdc-display-controller";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcd_base &pinctrl_lcd_rgb888>;
#address-cells = <1>;
#size-cells = <0>;
port@0 {
#address-cells = <1>;
#size-cells = <0>;
reg = <0>;
hlcdc_panel_output: endpoint@0 {
reg = <0>;
remote-endpoint = <&panel_input>;
};
};
};
hlcdc_pwm: hlcdc-pwm {
compatible = "atmel,hlcdc-pwm";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcd_pwm>;
#pwm-cells = <3>;
};
};
