mtk_clk_simple_probe() is a function that registers mtk gate clocks
and, if reset data is present, a reset controller and across all of
the MTK clock drivers, such a function is duplicated many times:
switch to the common mtk_clk_simple_probe() function for all of the
clock drivers that are registering as platform drivers.

cool, replace clk_mt8183_infra_probe and clk_mt8183_peri_probe with
mtk_clk_simple_probe

This looks mostly good, however ...

I'm not a big fan of mixing devres and non-devres teardown code. Automatic
devres teardown happens after the remove callback returns, so in this
case you could have child devices being unregistered that touch clocks
or resets that have already been unregistered and freed in the remove
callback.

Would this get cleaned up even more? I.e. have just one driver left and
we could have the nice *_platform_driver() macros.

I'll add a custom remove function that calls of_platform_depopulate() and
tears everything down manually in the correct order.

Thanks for catching this one, I didn't notice at all!

In the future, yes - granted that I find someone that can help with the testing,
as I don't have any MT2712 hardware here.

Not in this series though (please!).
