OK, posted three patches upstream...

A little hard to follow all the patches flying around (so I'll
probably reply a few different places with the same info), but I
believe that all of Addy's patches (with the exception of the one
intended to fix mmc_test which needs to be spun by him for a bugfix)
can be replaced with:

* mmc: dw_mmc: Don't start commands while busy

* mmc: dw_mmc: Make sure we only adjust the clock when power is on

* mmc: dw_mmc: Give a good reset after we give power

In order to avoid further spreading info out among several patches,
I'd request that you don't respond here but instead respond to my
posted patches. Thanks!
