It's now corrected to be 3.3v. Corresponding change in pbias regulator driver is already merged in ulf -next commit 27eae9d4b9d4cd9c204ef81f46078d91362ed41c Author: Ravikumar Kattekola Date: Thu Aug 31 15:48:45 2017 +0530 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.
