Currently UDC core calls ->udc_set_speed() with the speed parameter containing the maximum speed supported by the gadget function driver. This might very well be more than that supported by the UDC controller driver. Select the lesser of the 2 speeds so both UDC and gadget function driver are operating within limits. This fixes PHY Erratic errors and 2 second enumeration delay on TI's AM437x platforms. Fixes: 6099eca796ae ("usb: gadget: core: introduce ->udc_set_speed() method") Cc: <stable@vger.kernel.org> # v4.13+ Reported-by: Dylan Howey <Dylan.Howey@tennantco.com> Signed-off-by: Roger Quadros <rogerq@ti.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> |

README
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.
