Hi
Except mmsys (i added in Patch #1) all mt7623-compatibles are not defined in code and fallback (mt2701-x/mt8173-x) is used. If i add it in dt-binding, it should be added in code too, right? or should i remove mt7623 compatibles and only add documentation for new mmsys?
regards Frank

in drivers/gpu/drm/mediatek/mtk_mipi_tx.c only the compatible for mt2701 is defined (which is fallback in dts). So should i remove mt7623 compatible here and in the other occurences?

same here...only mt8173-cec is defined in drivers/gpu/drm/mediatek/mtk_cec.c

as i added this in driver, i add this to documentation (and maybe remove the fallback because it results in wrong routing?)

also not defined in drivers/gpu/drm/mediatek/mtk_drm_drv.c so again fallback used
