    Subject[PATCH RFC 0/2] Internal voltage control for platform drivers
    Date
    Certain SDHC controllers may require that voltage switching happen after
    sepcial conditions. Added a QUIRK for such controllers to use.

    For SDHCI-MSM controllers, power irq is a signal from controller to SW
    that it is ready for voltage switch. So added support to register
    voltage regulators from the msm driver and use them.
    Voltage switching from core layer is causing CRC/cmd timeout errors in
    some chipsets.

    Tested on: sdm845, db410c
    Requies patch series:"[PATCH V3 0/4] Changes for SDCC5 version"

    Vijay Viswanath (2):
    mmc: sdhci: Allow platform controlled voltage switching
    mmc: sdhci-msm: Use internal voltage control
