Changes from v1:
*) return on -EPROBE_DEFER and other fatal errors. (Don't return only
   if the return value is -ENODEV)
*) Remove the beagle x15 dts patch. It can be part of a different
   series.
*) Avoid using regulator_is_enabled for vqmmc since if the regulator
   is shared and the other users are not using regulator_is_enabled
   then there can be unbalanced regulator_enable/regulator_disable

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 and any other fatal errors
*) enable/disable vmmc_aux regulator based on prior state

I've pushed this patch series to
git://git.ti.com/linux-phy/linux-phy.git mmc_regulator_cleanup_fixes_v2

Please note the branch also has the pbias fixes [1] & [2].
[1] -> https://lkml.org/lkml/2015/7/27/358
[2] -> https://lkml.org/lkml/2015/7/27/391

This series is in preparation for implementing the voltage switch
sequence so that UHS cards can be supported.

Did basic read/write test in J6, J6 Eco, Beagle-x15, AM437x EVM,
Beaglebone black, OMAP5 uEVM and OMAP4 PANDA.

I have now done read/write test in omap3 beagle-xm with this series!

Thanks
Kishon
