Hi,
I'm working on IM8M MINI EVK Linux platform, we are working on integration of panasys LVDS display and we are using SN65DSI83 as an bridge converter.
I 'have applied below patch at the directory kernel-sourcr/.../git/drivers/gpu/drm/bridge.
and i have updated in my device tree file build/tmp/work-shared/imx8qmevk/kernel-source/arch/arm64/boot/dts/freescale/imx8mm-evk.dts as below
&lcdif{
max-res = <1280>, <1024>;
status = "okay";
};
&mipi_dsi {
status = "okay";
port@1 {
dsim_to_sn65dsi8: endpoint {
remote-endpoint = <&sn65dsi83_in>;
};
};
};
&i2c2 {
clock-frequency = <100000>;
pinctrl-names = "default";
status = "okay";
lvds_bridge: sn65dsi83@2c {
compatible = "ti,sn65dsi83";
reg = <0x2c>;
ti,dsi-lanes = <4>;
ti,lvds-format = <2>;
ti,lvds-bpp = <24>;
ti,width-mm = <376>;
ti,height-mm = <301>;
enable-gpios = <&gpio1 14 GPIO_ACTIVE_HIGH>;
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_dsi_lvds_bridge>;
status = "okay";
display-timings {
lvds {
/*

};
port {

};
};
};
};
after compiling and deploying the kernel using
bitbake -c compile -f linux-imx and bitbake -c deploy -f linux-imx then I have built entire image using bitbake imx-image-full. I cannot see any display on the LVDS ,can you help me where i was struck.
