Atmel LCDC Framebuffer
|
|
-----------------------------------------------------
|
|
|
|
Required properties:
|
|
- compatible :
|
|
"atmel,at91sam9261-lcdc" ,
|
|
"atmel,at91sam9263-lcdc" ,
|
|
"atmel,at91sam9g10-lcdc" ,
|
|
"atmel,at91sam9g45-lcdc" ,
|
|
"atmel,at91sam9g45es-lcdc" ,
|
|
"atmel,at91sam9rl-lcdc" ,
|
|
"atmel,at32ap-lcdc"
|
|
- reg : Should contain 1 register ranges(address and length)
|
|
- interrupts : framebuffer controller interrupt
|
|
- display: a phandle pointing to the display node
|
|
|
|
Required nodes:
|
|
- display: a display node is required to initialize the lcd panel
|
|
This should be in the board dts.
|
|
- default-mode: a videomode within the display with timing parameters
|
|
as specified below.
|
|
|
|
Optional properties:
|
|
- lcd-supply: Regulator for LCD supply voltage.
|
|
|
|
Example:
|
|
|
|
fb0: fb@0x00500000 {
|
|
compatible = "atmel,at91sam9g45-lcdc";
|
|
reg = <0x00500000 0x1000>;
|
|
interrupts = <23 3 0>;
|
|
pinctrl-names = "default";
|
|
pinctrl-0 = <&pinctrl_fb>;
|
|
display = <&display0>;
|
|
status = "okay";
|
|
#address-cells = <1>;
|
|
#size-cells = <1>;
