Subject: [PATCH 0/2] dra7/omap5: Increase max-voltage of pbias to 3.3v

Max voltage of pbias was set to 3.0v because of an error in TRM in
omap5/dra7 SoCs. It's now corrected to be 3.3v.

Corresponding change in pbias regulator driver is already merged in

    regulator: pbias: Select voltage table based on max-voltage
    
    Reference manuals of OMAP5x and DRA7x have been updated to reflect
    the PBIAS regulator max-voltage as 3.3V instead of 3.0V, while OMAP3x
    and OMAP4x are still quoting 3.0V. So, as of now, the pbias driver
    needs to support both 3.0V and 3.3V IO voltage based on the max-voltage
    supported by the PBIAS regulator.
