There was a minor upstream change to one of the files since I submitted v4 of my
cadence device-tree patchset, so I rebased and resent the patchset as a v5.  I
included everyone that was originally involved with the patches and added a CC
for Marek.

This is only the patchset for the device tree changes for the cadence qspi driver,
Simon will still have to add the patch that fixes the cache invalidation bug in the
cadence driver.
