So there's going to be no code sharing at all between this and any other
Mediatek chips? That seems very surprising, it'd suggest that the
hardware designers were creating a new design completely from scratch
each time which doesn't seem all that likely. This is an unusual way of
organizing things and we need a much clearer explanation of what's going
on here.
MT8173 and MT2701 are from different product lines so the register
control sequences are very different. If another driver for 8173-like
(or 2701-like) chip go upstream it shall share some common code with the
relatively driver indeed. However I think MT8173 and MT2701 can't share
the platform driver or a lot of "if MT8173 else MT2701" will mess up the
code.
What about the other SoCs we have some minimal support for: mt6589,
mt8135, mt6592, mt6580, mt7323, mt8127?
A quick glance at the datasheets showed me, that mt6589 and at least
mt8127 have quite similar register offsets. So I suppose there is some
common code actually.
