| Freescale imx21 Framebuffer |
| |
| This framebuffer driver supports devices imx1, imx21, imx25, and imx27. |
| |
| Required properties: |
| - compatible : "fsl,<chip>-fb", chip should be imx1 or imx21 |
| - reg : Should contain 1 register ranges(address and length) |
| - interrupts : One interrupt of the fb dev |
| |
| Required nodes: |
| - display: Phandle to a display node as described in |
| Documentation/devicetree/bindings/video/display-timing.txt |
| Additional, the display node has to define properties: |
| - bits-per-pixel: Bits per pixel |
| - fsl,pcr: LCDC PCR value |
| |
| Optional properties: |
| - lcd-supply: Regulator for LCD supply voltage. |
| - fsl,dmacr: DMA Control Register value. This is optional. By default, the |
| register is not modified as recommended by the datasheet. |
| - fsl,lpccr: Contrast Control Register value. This property provides the |
| default value for the contrast control register. |
| If that property is omitted, the register is zeroed. |
| - fsl,lscr1: LCDC Sharp Configuration Register value. |
| |
| Example: |
| |
| imxfb: fb@10021000 { |
| compatible = "fsl,imx21-fb"; |
| interrupts = <61>; |
| reg = <0x10021000 0x1000>; |
| display = <&display0>; |
| }; |
| |
| ... |
| |
| display0: display0 { |
| model = "Primeview-PD050VL1"; |
| native-mode = <&timing_disp0>; |
| bits-per-pixel = <16>; |
| fsl,pcr = <0xf0c88080>; /* non-standard but required */ |
| display-timings { |
| timing_disp0: 640x480 { |
| hactive = <640>; |
| vactive = <480>; |
| hback-porch = <112>; |
| hfront-porch = <36>; |
| hsync-len = <32>; |
| vback-porch = <33>; |
| vfront-porch = <33>; |
| vsync-len = <2>; |
| clock-frequency = <25000000>; |
| }; |
