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