"Newer designs should not use this bridge", but in patch 8 you are introducing a new use ot devm_drm_of_display_mode_bridge(). Shouldn't you instead "use proper panel driver instead" in patch 8? Can you point to the conversation where the converstaion where Dmitry suggested this change? Maybe it already contains the answer to my qustion. Also adding a link to that conversation in the commit message woule be useful. Luca -- Luca Ceresoli, Bootlin Embedded Linux and Kernel engineering https://bootlin.com
