There actually is a cover letter. The git-send-email "cccmd =
scripts/get_maintainer.pl" hook doesn't work for the cover letter though
because it isn't a patch. I've hand-picked some people who
touched/reviewed the driver before to the git-send-email command line,
but everybody else got the patches only.
Anyone has a good solution for this btw?

The driver is out of tree still, these are cleanups Ulf Hansson asked
for last time the driver was submitted.
Full set of patches:
Plan for upstream merge is to actually squash all the incremental
cleanups, but for now I kept them as separate changes. I think this
makes it easier to spot mistakes and it'll also help in case there are
regressions b/c you can bisect things.

The 2835 has two SD controllers: The Arasan SDHCI controller that we
currently use (iproc drives that one), and a custom SD controller.
This is a driver for the custom one. Has better performance than the
sdhci controller (according to Eric Anholt). For the rpi3 switching to
this driver has the additional advantage that we can use the iproc
driver driver to handle the wifi.
