This patch series does the following
*) Uses devm_regulator_get_optional() for vmmc and then removes the
CONFIG_REGULATOR check altogether.
*) return on -EPROBE_DEFER
*) enable/disable vmmc_aux
No functional change. Instead of using omap_hsmmc_host's vcc and vcc_aux
members, use vmmc and vqmmc present in mmc_host which is present
for the same purpose.

vdd voltage is set in mmc core to ios-vdd and vmmc should actually
be set to this voltage. Modify omap_hsmmc_enable_supply
to not take vdd as argument since now it's directly set to
the voltage in ios-vdd.

Now that support for platforms which have optional regulator is added,
remove CONFIG_REGULATOR check in omap_hsmmc.

Return error if any of the regulator APIs (regulator_enable,
regulator_disable, regulator_set_voltage) fails in
omap_hsmmc_set_power to avoid undefined behavior.

Now return error only if the return value of
devm_regulator_get_optional() is not the same as -ENODEV, since with
-EPROBE_DEFER, the regulator can be obtained later and all other
errors are fatal.

Fix the error handling code in case pm_runtime_get_sync fails. Now
when pm_runtime_get_sync fails pm_runtime_disable is invoked so that
there is no unbalanced pm_runtime_enable calls.

Add support for vmmc_aux to switch to 1.8v. Also use iov instead of
vdd to indicate io voltage. This is in preparation for adding support
for io signal voltage switch.

of the tuning end flag. Assertion of tuning end flag is what
masks the interrupts. Because of this race, an erroneous DCRC
interrupt occurs.
The suggested workaround is to disable DCRC interrupts during
the tuning procedure which is implemented here.

Add a separate function to set the UHSMS field to one
of SDR104, SDR50, DDR50, SDR25 or SDR12 depending on the
inserted SD card. This is required for
tuning to succeed in the case of SDR104/HS200 or SDR50.
