imx8mq evk device tree with sn65dsi83 issue

[Ichi_]

Hi all

The yocto linux version : 6.6.23

I have canceled adv7535 settings(Makefile) and add sn65dsi83 in imx8mq-evk.dts, but it looks some duplicate definitions.

Does any one have any suggestions about sn65dsi83 with 6.6.23 porting?Thanks.

The Error message as below:

ERROR (duplicate_label): /soc@0/bus@30800000/dsi@30a00000/ports/port@0/endpoint: Duplicate label 'mipi_dsi_in' on /soc@0/bus@30800000/dsi@30a00000/ports/port@0/endpoint and /soc@0/bus@30800000/dsi@30a00000/ports/port@0/endpoint@1

ERROR (duplicate_label): /soc@0/bus@32c00000/display-controller@32e00000/port/endpoint: Duplicate label 'dcss_out' on /soc@0/bus@32c00000/display-controller@32e00000/port/endpoint and /soc@0/bus@32c00000/display-controller@32e00000/port@0/endpoint

Hi Zhiming_Liu

The imx8-evk.dts and Makefile.7z has been uploaded.

Thanks
