-Subject: [PATCH] mmc: sdhci-iproc: Fix vmmc regulators on iProc
-
-The Linux support for controlling card power via regulators appears to
-be contentious. I would argue that the default behaviour is contrary to
-the SDHCI spec - turning off the power writes a reserved value to the
-SD Bus Voltage Select field of the Power Control Register, which
-seems to kill the Arasan/iProc controller - but fortunately there is a
-hook in sdhci_ops to override the behaviour. Borrow the implementation
-from sdhci_arasan_set_power.
