I'd do two patches for this. The stuff your doing is too disconnected.

There is a whole bunch of unused code in the clock files and it's being
deleted. I don't see a point of splitting it up per file.

It's easier to review when changes aren't merged that don't related to
each other.

In this particular case, the patch is a bunch of removal of dead code,
and kind of makes sense to keep it together. I'm fine with it as is.

He's adding stuff too .. So it's not _just_ removal which is what I was
getting at.

The clock debugfs code is large enough, and easy enough to separate,
that it deserves its own file which is compiled only when
CONFIG_DEBUG_FS is enabled.
Also, cleanup header file #includes that are no longer required.

There are currently 3 separate directories for clock debugging in
debugfs: clk_enable, clk_rate, and clk_local. Each of these
directories contains a list of clocks. This is rather annoying
when you are focusing on one clock and want to enable/disable it
and then check its rate. You either have to cd to the other
directory or cat ../clk_rate/<clk>.
Invert the layout so that there is one clock directory containing
a directory for each clock. Inside each respective clock
directory place an enable, rate, and is_local file relating to
the clk_enable, clk_disable, and clk_local directories that exist
today.

Support the CE_CLK and CODEC_SSBI_CLK. Also add support for uart,
and i2c clocks on targets which support proc_comm clocks.

Basically when you catch yourself writing "also" in the commit text you
need to re-evaluate making two patches.. In this case it looks
appropriate..
I'd do CE_CLK and CODEC_SSBI_CLK in one, with the increment for the
number of clocks, and adding those two clocks.
Then the rest of it I'm not sure. If it was me I'd break out uart and
i2c in different patches but that might be overkill.

Or it is just an argument to not use the word also in the commit text.
I don't think it's really necessary to split up a patch that adds a few
clocks to the clock table.

This one it actually makes a lot of sense to break it up. He's doing
some very different things here all in the same patch ..
