| * Currus 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. | 
 |  |
