Subject: [PATCH v2 0/3] Fix fixed regulators support

Hello,

Commit f0f98b19e23d4426ca185e3d4ca80e6aff5ef51b revealed that the support for
fixed regulators in SDHCI driver was working only by pure luck. My previous
patch set for fixing this issue resulted in a discussion, which has been
concluded that this issue should by fixed by extending regulators core by
regualtor_can_change_voltage() function and using it in the mmc/sdhci drivers.

For more information, please refer to the following threads:

Best regards

Patch summary:

Marek Szyprowski (3):
  regulators: add regulator_can_change_voltage() function
  mmc: use regulator_can_change_voltage() instead of
    regulator_count_voltages() hacks
  mmc: sdhci: check voltage range only on regulators aware of voltage
    value
