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>;
|
|
};
|
|
};
