[PATCH 2/3] clk: mediatek: clk-mt8192: drop CLK_OF_DECLARE_DRIVER

[Miles Chen]

clk-mt8192.c uses CLK_OF_DECLARE_DRIVER and it does not work for
kernel modules.

To support clk-mt8192 moudle build, move the
clk_mt8192_top_init_early() logic to clk_mt8192_top_probe()
and drop clk_mt8192_top_init_early() and CLK_OF_DECLARE_DRIVER.

Re: [PATCH 3/3] clk: mediatek: support COMMON_CLK_MT8192 module build

[Miles Chen]

Hi,

>Have you tried removing the modules? And then reloading them? I also see

Thanks for the comment.
I did not try it because we do not unload our clk modules.
After testing I understand that the clock driver does not unregister clks so 
we cannot remove then unload it.

I think I have to add some unregister logic to these drivers.

You meant that mtk_clk_simple_probe() has no unregister logic in error path?

Sorry for that, I will submit a cover letter in next version.

I post a patch to fix this first:
https://lore.kernel.org/lkml/20220117090030.13064-1-miles.chen@mediatek.com/T/#u

After this, I think that I can use mtk_clk_simple_probe() in other mediatek clk
drivers by submitting some clean up patches.
