This supports USB2 PHY channel #0 on ULCB Kingfisher board The dedicated USB0_PWEN pin is used to control CN13 VBUS source from U43 power supply. MAX3355 can also provide VBUS, hence it should be disabled via OTG_OFFVBUSn node coming from gpio expander TCA9539. Set MAX3355 enabled using OTG_EXTLPn node to be able to read OTG ID of CN13.

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.
