* Cirrus Logic CLPS711X Framebuffer Required properties: - compatible: Shall contain "cirrus,ep7209-fb". - reg : Physical base address and length of the controller's registers + location and size of the framebuffer memory. - clocks : phandle + clock specifier pair of the FB reference clock. - display : phandle to a display node as described in Documentation/devicetree/bindings/display/panel/display-timing.txt. Additionally, the display node has to define properties: - bits-per-pixel: Bits per pixel. - ac-prescale : LCD AC bias frequency. This frequency is the required AC bias frequency for a given manufacturer's LCD plate. - cmap-invert : Invert the color levels (Optional). Optional properties: - lcd-supply: Regulator for LCD supply voltage. Example: fb: fb@800002c0 { compatible = "cirrus,ep7312-fb", "cirrus,ep7209-fb"; reg = <0x800002c0 0xd44>, <0x60000000 0xc000>; clocks = <&clks 2>; lcd-supply = <®5v0>; display = <&display>; }; display: display { model = "320x240x4"; bits-per-pixel = <4>; ac-prescale = <17>; display-timings { native-mode = <&timing0>; timing0: 320x240 { hactive = <320>; hback-porch = <0>; hfront-porch = <0>; hsync-len = <0>; vactive = <240>; vback-porch = <0>; vfront-porch = <0>; vsync-len = <0>; clock-frequency = <6500000>; }; }; };
