The AST2400 contains several USB controllers: * USB 1.1 Host Controller * USB 2.0 Host Controller * USB 2.0 Virtual Hub * USB 1.1 HID Controller Pins for three ports are routed to the three controllers such that: * Port 1 is a dedicated USB 1.1 host port * Port 2 is shared between the USB 1.1 host and HID controllers * Port 3 is shared between the USB 2.0 host and Hub controllers As the pins for port 1 are fixed function there is no associated mux function or group described in the bindings. Ports 2 and 3 are muxed as above, and the table below describes the mapping between pinmux function names and ports: Port | USB Version | USB Mode | Mux Function ------|--------------|-----------|------------- 1 | 1.1 | Host | - 2 | 1.1 | Host | USB11H2 2 | 1.1 | HID | USB11D1 3 | 2.0 | Host | USB2H1 3 | 2.0 | Device | USB2D1 Signed-off-by: Andrew Jeffery <andrew@aj.id.au> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org> |

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.
