The MIPI DSI controller in Allwinner A64 is similar to A33. But unlike A33, A64 doesn't have DSI_SCLK gating so it is valid to have separate compatible for A64 on the same driver. DSI_SCLK uses mod clock-names on dt-bindings, so the same is not required for A64. On that note - A64 require minimum of 1 clock like the bus clock - A33 require minimum of 2 clocks like both bus, mod clocks So, update dt-bindings so-that it can document both A33, A64 bindings requirements.
