The .bpc = 6 implies .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , add the missing bus_format. Add missing connector type and bus_flags as well. Documentation [1] 1.4 GENERAL SPECIFICATI0NS indicates this panel is capable of both RGB 18bit/24bit panel, the current configuration uses 18bit mode, .bus_format = MEDIA_BUS_FMT_RGB666_1X7X3_SPWG , .bpc = 6. Support for the 24bit mode would require another entry in panel-simple with .bus_format = MEDIA_BUS_FMT_RGB666_1X7X4_SPWG and .bpc = 8, which is out of scope of this fix.
