Comment(by cjb):

 Thanks, interesting!  You managed to capture the relevant part.

 We're turning the clock off on the way into suspend and then not bringing
 it back.  I think it makes sense that the clock goes off on the way into
 suspend, because we move to 1-bit mode and that doesn't need a clock.
 It's supposed to come back when we move into 4-bit mode at resume time,
 though, I'd have thought.

 Sure would be interesting to compare this MMC_DEBUG log with the log from
 a working 1.5 network-associated resume.  That would tell us whether/when
 the clock's supposed to come back.
