[PATCH 07/12] mmc: sdhci-pxav3: Try to get named I/O clock first

From: Sebastian Hesselbarth
Date: Fri Oct 03 2014 - 11:59:09 EST


With support for more than one clock, we'll need to distinguish between
the clock by name. Change clock probing to first try to get "io" clock
before falling back to unnamed clock.
