Device Tree bindings for Armada DRM CRTC driver
Required properties:
- compatible: value should be "marvell,dove-lcd".
- reg: base address and size of the LCD controller
- interrupts: single interrupt number for the LCD controller
- port: video output port with endpoints, as described by graph.txt
Optional properties:
- clocks: as described by clock-bindings.txt
- clock-names: as described by clock-bindings.txt
"axiclk" - axi bus clock for pixel clock
"plldivider" - pll divider clock for pixel clock
"ext_ref_clk0" - external clock 0 for pixel clock
"ext_ref_clk1" - external clock 1 for pixel clock
Note: all clocks are optional but at least one must be specified.
Further clocks may be added in the future according to requirements of
different SoCs.
Example:
lcd0: lcd-controller@820000 {
compatible = "marvell,dove-lcd";
reg = <0x820000 0x1000>;
interrupts = <47>;
clocks = <&si5351 0>;
clock-names = "ext_ref_clk_1";
};
