Now that we have support for the AXP221 PMIC's USB VBUS detection and DRIVEVBUS vbus control, we can use the USB OTG port in proper OTG mode. This patch enables the aforementioned PMIC functions, adds the OTG ID detection pin to the USB PHY node, and changes the mode of USB OTG to "otg".

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.
