But after reading Angelo's comment, we thought it is necessary to create a new compatible to avoid confusion for users. https://lore.kernel.org/lkml/bf8394c6-5460-8696-f46b-0c39927aaf84@collabora.com/ Although they are fully compatible, developers cannot arbitrarily replace the chip on the board with another one. So separated bindings might be better. > Best regards, > Krzysztof Thanks Macpaul Lin
