The A64 MIPI DPHY one needs to be always set with the A31 fallback, but the A31 is also usable on its own. Maxime

That's not my point. You removed from the binding documentation that allwinner,sun6i-a31-mipi-dphy was a valid option on its own. It's not ok to do so. Maxime

The MIPI DSI PHY HDMI controller on Allwinner A64 is similar on the one on A31. Add A64 compatible and append A31 compatible as fallback.
