Where is mmc.txt?

This isn't correct.  I think you mean it must be a phandle to the
'mmc' clock.  It's also worth referencing the clock DT documentation
here.

> +Optional properties:

What is it; integer, string, phandle, something else?

> +- non-removable: non-removable slot (bindings/mmc/mmc.txt).

This however, _is_ a string, so you need to put it in "'s like you did
with "mmc" above and/or reference the file which documents it.

I don't think you need clock-names if you only have one clock.

Once fixed you can add my Ack for the next submission:
