I didn't have anything useful to write in it. Will provide you one in
the future...

You don't think it's a little bit odd to have description such as
"Sleep", "PCIe 2a pipe" or First EMAC controller reference"?

I mean I agree that it's obviously clocks we're talking about, but to me
that makes it seems like the descriptions are cut short, just for the
sake of avoiding "clock".

In this case I think they should include _clk, as they actually matches
the clock names in the documentation.
