[PATCH 00/15] mmc: bcm2835: second cleanup for sdhost driver

[Stefan Wahren]

Hi Gerd,

here is the promised second cleanup round for the sdhost driver on
bcm2835. Except of patch #3 these are more non-functional changes.
Please squash them in your repo.

Now the performance results after applying your and my patch series:
