This patchset brings the support for Analogix ANX6345 RGB-(e)DP bridge, which is used by some Allwinner A64 laptops, such as Pinebook and Olimex TERES-I. It reuses some definitions from the ANX78xx driver that already exists in the kernel tree, but the driver code itself is rewritten, because the big difference between ANX6345 and ANX78xx. This patchset also enables the bridge on Pinebook and TERES-I, and a temporary workaround patch (do not merge) for the dot clock accuracy problem of sun4i-drm. This patchset assumes some fixes ([1], [2] and [3]) are already applied, without them the patchset cannot be tested on the A64 devices mentioned above.
