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 regulator based on prior state 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.
