Display device
This chapter describes how to set up the display device in the device tree. Here, the LCD display is connected in
LVDS0 channel. The LCD display supports 800x480 resolution, RGB666 pixel format and 16 bpp.
Add the display formats in the frame buffer as mentioned below.
mxcfb1: fb@0 {
compatible = "fsl,mxc_sdc_fb";
disp_dev = "ldb";
interface_pix_fmt = "RGB666";
default_bpp = <16>;
int_clk = <0>;
late_init = <0>;
status = "disabled";
};
Add the display timing parameters such as horizontal and vertical active period, blanking period, pixel clock,
etc., as mentioned below.
&ldb {
status = "okay";
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <18>;
primary;
crtc = "ipu1-di0";
status = "okay";
display-timings {
native-mode = <&timing0>;
timing0: ldb-wvga {
clock-frequency = <33260000>;
hactive = <800>;
vactive = <480>;
hback-porch = <88>;
hfront-porch = <40>;
vback-porch = <33>;
vfront-porch = <10>;
hsync-len = <128>;
vsync-len = <2>;
};
};
};
};
