The "Verify that bus sockets are present" example was not properly formatted due to a typo in the literal block marker. Signed-off-by: Justin Swartz Link: https://lore.kernel.org/r/20220604155431.23246-1-justin.swartz@risingedge.co.za Signed-off-by: Jonathan Corbet

usb: gadget: uvc: allow changing interface name via configfs

2022-04-21T16:14:34Z

Add a configfs entry, "function_name", to change the iInterface field for VideoControl. This name is used on host devices for user selection, useful when multiple cameras are present. The default will remain "UVC Camera". Signed-off-by: Dan Vacura Link: https://lore.kernel.org/r/20220401160447.5919-1-w36195@motorola.com Signed-off-by: Greg Kroah-Hartman

usb: gadget: f_uac2: Optionally determine bInterval for HS and SS

2022-01-31T13:26:18Z

Allow setting configfs params p_hs_bint/c_hs_bint to 0. If they are set to 0, determine the largest bInterval (4 to 1) for which the required bandwidth of the max samplerate fits the max allowed packet size. If the required bandwidth exceeds max bandwidth for single-packet mode (ep->mc=1), keep bInterval at 1. The FS speed is left at fixed bInterval=1. If for any speed the required bandwidth exceeds the max bandwidth corresponding to the selected/determined bInterval, print a warning.

usb: gadget: f_uac2: Add HS/SS bInterval to configfs

2022-01-31T13:26:18Z

Allow configuring the HS/SS bInterval through configfs, via parameters p_hs_bint/c_hs_bint separately for playback/capture. The default param values are left at the original 4.

usb: gadget: f_uac2: allow changing interface name via configfs

2022-01-26T13:10:44Z

This adds "function_name" configfs entry to change string value of the iInterface field. This field will be shown in Windows' audio settings panel, so being able to change it is useful. It will default to "Source/Sink" just as before. Signed-off-by: Yunhao Tian Link: https://lore.kernel.org/r/20220122112446.1415547-2-t123yh.xyz@gmail.com Signed-off-by: Greg Kroah-Hartman

usb: gadget: f_uac1: allow changing interface name via configfs

2022-01-26T13:10:40Z

This adds "function_name" configfs entry to change string value of the iInterface field. This field will be shown in Windows' audio settings panel, so being able to change it is useful. It will default to "AC Interface" just as before if unchanged.

usb: gadget: f_uac1: Support multiple sampling rates

2022-01-26T13:06:08Z

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 is updated. 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_uac1.

usb: gadget: f_uac2: Support multiple sampling rates

2022-01-26T13:06:08Z

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.
