2020-10-30docs: ABI: testing: make the files compatible with ReST outputMauro Carvalho Chehab
Some files over there won't parse well by Sphinx. Fix them.

2020-01-15usb: gadget: configfs: Add max_speed settingThinh Nguyen
Some functions support speeds other than SuperSpeed. Add max_speed attribute to configfs gadget allowing user to specify the maximum speed the composite driver supports. The valid input speed names are super-speed-plus, super-speed, high-speed, full-speed, and low-speed.

2014-05-14usb: gadget: configfs: OS Extended Properties descriptors supportAndrzej Pietrasiewicz
Add handling of OS Extended Properties descriptors from configfs interface. One kind of "OS Descriptors" are "Extended Properties" descriptors, which need to be specified per interface or per group of interfaces described by an IAD. This patch adds support for creating subdirectories in interface.<n> directory located in the function's directory. Names of subdirectories created become names of properties. Each property contains two attributes: "type" and "data". The type can be a numeric value 1..7 while data is a blob interpreted depending on the type specified. The types are: 1 - unicode string 2 - unicode string with environment variables 3 - binary 4 - little-endian 32-bit 5 - big-endian 32-bit 6 - unicode string with a symbolic link 7 - multiple unicode strings Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2014-05-14usb: gadget: configfs: OS Extended Compatibility descriptors supportAndrzej Pietrasiewicz
Add handling of OS Extended Compatibility descriptors from configfs interface. Hosts which expect the "OS Descriptors" ask only for configurations @ index 0, but linux-based USB devices can provide more than one configuration. This patch adds marking one of gadget's configurations the configuration to be reported at index 0, regardless of the actual sequence of usb_add_config invocations used for adding the configurations. The configuration is selected by creating a symbolic link pointing to it from the "os_desc" directory located at the top of a gadget's directory hierarchy. One kind of "OS Descriptors" are "Extended Compatibility Descriptors", which need to be specified per interface. This patch adds interface.<n> directory in function's configfs directory to represent each interface defined by the function. Each interface's directory contains two attributes: "compatible_id" and "sub_compatible_id", which represent 8-byte strings to be reported to the host as the "Compatible ID" and "Sub Compatible ID".

2014-05-14usb: gadget: configfs: OS String supportAndrzej Pietrasiewicz
Add handling of OS String extension from the configfs interface. A directory "os_desc" is added at the top level of a gadget's directories hierarchy. In the "os_desc" directory there are three attributes: "use", "b_vendor_code" and "qw_sign". If "use" contains "0" the OS string is not reported to the host. "b_vendor_code" contains a one-byte value which is used for custom per-device and per-interface requests. "qw_sign" contains an identifier to be reported as the "OS String" proper.
