Have a 12 MHz fixed CEC clock source connected to the CEC_CLK pin on ADV7511: - r8a7790/lager - r8a7791/koelsch - r8a7791/porter - r8a7792/blanche - r8a7793/gose - r8a7794/alt - r8a7794/silk I don't know about r8a7792/wheat. But according to its .dts file, it has two instances of the ADV7513, not ADV7511.
