   4 Subject: [PATCH 542/703] mmc: sdhci-iproc: Add support for emmc2 of the
   5  BCM2838
   6
   7 The emmc2 interface of the BCM2838 should be integrated in sdhci-iproc
   8 to avoid code redundancy. Except 32 bit only access no other quirks are
   9 known yet. Add an additional compatible string for upstream proposal.
