R40 display pipeline has a lot of possible configurations. HDMI can be connected to 2 different TCONs (out of 4) and mixers can be connected to any TCON. All this must be configured in TCON TOP.
Along with definition of TCON capabilities also add mux callback, which can configure this complex pipeline.
For now, only TCON TV is supported.

Are TCON-TOPs going to be a common thing in new SoCs from Allwinner? If so, maybe we should add an index to the TCON quirks and have a common TCON-TOP set_mux function.
Actually, that only moves it up a level. Should it be a devicetree property?
Thanks,
