Hmm, maybe we should convert this to only listing SoCs with two clocks?
That will be easier to maintaine since the majority seems to have one.

That is actually mentioned in the paragraph above:

- clocks: Most controllers only have 1 clock source per channel. However, on
          some variations of this controller, the internal card detection
          logic that exists in this controller is sectioned off to be run by a
          separate second clock source to allow the main core clock to be turned
          off to save power.

so I suggest just integrating the (short) list in that paragraph.

Bogus trailing double quote.

Its probably time for some fallback compatibility strings but
I think that should be done as follow-up (likely by me) in a considered
way. So this patch is fine in my books.
