mfd: Add documentation for atmel-hlcdc DT bindings
The HLCDC IP available on some Atmel SoCs (i.e. at91sam9n12, at91sam9x5 family or sama5d3 family) exposes 2 subdevices: - a display controller (controlled by a DRM driver) - a PWM chip This patch adds documentation for atmel-hlcdc DT bindings.

Device-Tree bindings for Atmel's HLCDC (High LCD Controller) MFD driver
|
||||
|
||||
Required properties:
|
||||
- compatible: value should be one of the following:
|
||||
"atmel,sama5d3-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 ../drm/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>;
|
||||
};
|
||||
};
