hello
@brian14 sir
Now i am working the custom Board
i need support for DP(Display port)
Here is my software details
Driver-Cadence DP DRM driver
DTS(Device tree source):
/dts-v1/;
#include "imx8mq-iwg33d-prgwd.dts"
&irqsteer {
status = "okay";
};
&dcss {
status = "okay";
disp-dev = "hdmi_disp";
port@0 {
dcss_out: endpoint {
remote-endpoint = <&hdmi_in>;
};
};
};
&hdmi {
compatible = "cdn,imx8mq-dp";
lane-mapping = <0xc6>;
hdcp-config = <0x3>;
status = "okay";
port@1 {
hdmi_in: endpoint {
remote-endpoint = <&dcss_out>;
};
};
};
And Also i Disabled the HDMI support as well
By following the above:
cdns-mhdp-imx 32c00000.hdmi: lane-mapping 0xc6
[drm] Both HDCP 1.4 and 2.2 are enabled
cdns-mhdp-imx 32c00000.hdmi: wrong link rate index
imx-dcss 32e00000.display-controller: bound 32c00000.hdmi (ops cdns_mhdp_imx_ops)
[drm] Initialized imx-dcss 1.0.0 20190917 for 32e00000.display-controller on minor 0
i getting this error prints
For DP :
flashed through DP bin and dtb has been changed in uboot as well
