Ruslan Bilovol 0356e6283c usb: gadget: f_uac1: add volume and mute support ... This adds bi-directional (host->device, device->host) volume/mute support to the f_uac1 driver by adding Feature Units and interrupt endpoint. Currently only master channel is supported. Volume and mute are configurable through configfs, by default volume has -100..0 dB range with 1 dB step. Similar to existing flexible endpoints configuration, Feature Unit won't be added to the topology if both mute and volume are not enabled, also interrupt endpoint isn't added to the device if no feature unit is present Signed-off-by: Ruslan Bilovol <ruslan.bilovol@gmail.com> Signed-off-by: Pavel Hofman <pavel.hofman@ivitera.com> Link: https://lore.kernel.org/r/20210712125529.76070-5-pavel.hofman@ivitera.com Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2021-07-21 10:10:11 +02:00
