Commit Message

AngeloGioacchino Del Regno Feb. 6, 2023, 3:28 p.m. UTC 
Change the custom mt8365_simple_gate to be mtk_gate clocks and
audio clocks to be composites to be consistent with all of the
other MediaTek clock drivers, allowing to convert this entire
driver to use the common mtk_clk_simple_probe() mechanism that
also allows building this driver as module.

While at it, also perform some macro compression cleanups and
switch to use module_platform_driver().

I think this would be easier to follow if it were split in half:
the first half migrating mt8365_simple_gate to mtk_gate, and the
second half converting to mtk_clk_simple_probe.

I assume git would generate better diffs after that.

This would get split in half as well. The macro cleanups go with the
first half, and the switch to module_platform_driver goes with the
second.

This should be in the previous patch?

Could you also remove some of the other inclusions that don't get
referenced after this patch?

Misc. unmentioned change. It makes sense, but please mention it.

I agree, entirely. Will do that on v2.
