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:
- fsl,dmacr: DMA Control Register value. This is optional. By default, the
register is not modified as recommended by the datasheet.
- 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>;
};
};
};

now is i2c. now is i2c, and the supported chips are ssd1306 and ssd1307.
- reg: Should contain address of the controller on the I2C bus. Most likely - reg: Should contain address of the controller on the I2C bus. Most likely
0x3c or 0x3d 0x3c or 0x3d
- pwm: Should contain the pwm to use according to the OF device tree PWM - pwm: Should contain the pwm to use according to the OF device tree PWM
specification [0] specification [0]. Only required for the ssd1307.
- reset-gpios: Should contain the GPIO used to reset the OLED display - reset-gpios: Should contain the GPIO used to reset the OLED display
- solomon,height: Height in pixel of the screen driven by the controller
- solomon,width: Width in pixel of the screen driven by the controller
- solomon,page-offset: Offset of pages (band of 8 pixels) that the screen is
mapped to.
Optional properties: Optional properties:
- reset-active-low: Is the reset gpio is active on physical low? - reset-active-low: Is the reset gpio is active on physical low?
