> So, the driver has to be panel-fannal-c3004.c and binding to be fannal,c3004.yaml. I believe I have covered this and all the other problems in following patch which I will submit as a V3 of the conversation in a patchset together with a driver: Add dt-bindings documentation for panel-mipi-dsi-bringup which currently supports fannal,c3004 panel. Also added fannal to vendor-prefixes.
