I'm still lost on the usage of CLK_OF_DECLARE here. What part of
these clk controllers needs to be registered to make the timer
work?

I also don't understand why we don't have different files and
drivers for all these different clock controllers? They all have
a similar probe structure, sure, but otherwise these are
different devices with different clks for them. The whole #ifdef
thing in the later patch would go away too.

Shouldn't be __init because it's driver probe path.

Please add some mtk here, 'clk_drv' is too generic.

This is unnecessary.

Just drop of_match_ptr() because it's not helping. Also
of_clk_match_tbl is too generic.

GPT (mtk-timer.c) may need infracfg and topckgen clocks. MT8173 for
example:

	timer: timer@10008000 {
	[...]
		clocks = <&infracfg CLK_INFRA_CLK_13M>,
			 <&topckgen CLK_TOP_RTC_SEL>;
	};

Yes, you are right. So you prefer to support subsystem clocks in
separated files such as clk-mt2701-mm.c, clk-mt2701-bdp.c and so on,
right?

But even if we implement subsystem clock in separated files, we still
need a way to make them optional. So the config options and #ifdef may
not be removed.

I use builtin_platform_driver_probe(clk_drv, clk_probe) to register this
driver, and it looks can be __init.

Ok. It should be possible to only register the clk tree for these
clks in CLK_OF_DECLARE() and then register the other clks that
the clk provider provides with a regular driver probe routine.
That way we can get the advantage of the device framework, etc.
but still register the clks we need to make the timer work early
on.

Presumably different files could just not be compiled if the
config is disabled, thus removing any need for #ifdef.

Ok, but that doesn't work with deferred probe right? It may be
better to avoid it then.

I'll study a new way to separate clock registration of a subsystem into
CLK_OF_DECLARE() and device probe().

OK. I'll try to implement these subsystem clocks into separated files in

It may be a concern. I'll investigate a proper way to implement the init
functions.
