I am using Linux 4.14.98 BSP. I'm using panel raydium 67198 which supports 1080p resolution. My display works fine if I use DCSS as input source for MIPI DSI. If I change it to LCDIF, frame buffer is created. But nothing comes up on display and there is no error print either.
I verified the clocks as well.
1)In case of DCSS, IMX8MQ_CLK_DC_PIXEL is 120MHz, IMX8MQ_VIDEO_PLL1_OUT is 1200MHz.
2)In case of LCDIF, IMX8MQ_CLK_LCDIF_PIXEL is 120MHz, IMX8MQ_VIDEO_PLL1_OUT is 1200MHz.
1) Device tree in case of DCSS:-
&dcss {
status = "okay";
disp-dev = "mipi_disp";
/*Here clock configuration is there in my dts*/
dcss_disp0: port@0 {
reg = <0>;
dcss_disp0_mipi_dsi: mipi_dsi {
remote-endpoint = <&mipi_dsi_in>;
};
};
};
&mipi_dsi {
status = "okay";
port@1 {
mipi_dsi_in: endpoint {
remote-endpoint = <&dcss_disp0_mipi_dsi>;
};
};
};
2) Device tree in case of LCDIF:-
&lcdif {
status = "okay";
max-res = <1080>, <1920>;
port@1 {
lcdif_mipi_dsi: mipi-dsi-endpoint {
remote-endpoint = <&mipi_dsi_in>;
};
};
};
&mipi_dsi {
status = "okay";
as_bridge;
pwr-delay = <10>;
port@1 {
mipi_dsi_in: endpoint {
remote-endpoint = <&lcdif_mipi_dsi>;
};
};
};
Note:- I'm testing same panel and I have no issues with DCSS as input source.
