This patch adds debugfs to set the "b-device" mode for using a board which is not connected to the ID pin (e.g. CN11 on Salvator-X). If we want to use peripheral mode on such a board, we have to disable VBUS output first. So, this patch can set such a mode as the following: # mount -t debugfs none /sys/kernel/debug # modprobe renesas_usb3 # modprobe g_mass_storage file=/dev/shm/test.bin # echo 1 > /sys/kernel/debug/ee020000.usb/b_device Signed-off-by: Yoshihiro Shimoda <yoshihiro.shimoda.uh@renesas.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> |

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.
