usb: gadget: f_uac2: Support multiple sampling rates
A list of sampling rates can be specified via configfs. All enabled sampling rates are sent to the USB host on request. When the host selects a sampling rate, the internal active rate (stored in struct f_uac2) is updated. The gadget no longer supports only one frequency. Therefore USB strings corresponding to the clock sources are renamed from specific Hz value to general names Input clock/Output clock. Config strings with single value stay compatible with the previous version. Multiple samplerates passed as configuration arrays to g_audio module when built for f_uac2.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. 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.
