[PATCH 00/17] omap_hsmmc: regulator usage cleanup and fixes

[Kishon Vijay Abraham I]

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.

  mmc: host: omap_hsmmc: use devm_regulator_get_optional() for vmmc
  mmc: host: omap_hsmmc: return error from omap_hsmmc_reg_get on
    -EPROBE_DEFER
  mmc: host: omap_hsmmc: cleanup omap_hsmmc_reg_get()
  mmc: host: omap_hsmmc: use the ocrmask provided by the vmmc regulator
  mmc: host: omap_hsmmc: use mmc_host's vmmc and vqmmc
  mmc: host: omap_hsmmc: remove unnecessary pbias set_voltage
  mmc: host: omap_hsmmc: return error if any of the regulator APIs fail
  mmc: host: omap_hsmmc: add separate functions for enable/disable
    supply
  mmc: host: omap_hsmmc: add separate function to set pbias
  mmc: host: omap_hsmmc: avoid pbias regulator enable on power off
  mmc: host: omap_hsmmc: don't use ->set_power to set initial regulator
    state
  ARM: dts: am57xx-beagle-x15: Fix regulator populated in MMC1 dt node
  mmc: host: omap_hsmmc: enable/disable vmmc_aux regulator based on
    prior state
  mmc: host: omap_hsmmc: use regulator_is_enabled to find pbias status
  mmc: host: omap_hsmmc: use ios->vdd for setting vmmc voltage
  mmc: host: omap_hsmmc: remove CONFIG_REGULATOR check

Roger Quadros (1):
  mmc: host: omap_hsmmc: use "mmc_of_parse_voltage" to get ocr_avail
