On newer Allwinner SoCs (H3 and after), the PHY0 node is routed to both MUSB controller for peripheral and host support (the host support is slightly broken), and a pair of EHCI/OHCI controllers, which provide a better support for host mode. Add support for automatically switch the route of PHY0 according to the status of dr_mode and id det pin. Only H3 have this function enabled in this patch, as further SoCs will be tested later and then have it enabled. As H5 is reusing the PHY driver of H3, this function is also enabled.

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.
