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.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
