Original commit credit to Amaury Pouly, Moshe Piekarski Pushed across the finish line by Dana Conrad To enable, see setting under General Settings --> System --> USB-DAC. On devices with few endpoints, this may not work while HID and/or mass storage is enabled. Adds new dedicated mixer channel. setting usb-dac can have values: - never (0) - always (1) - while_charge_only (2) - while_mass_storage (3) Relevant devices are DWC2 and ARC usb controller devices. That being: x1000 Native targets (m3k, erosqnative, q1, others...?), sansac200, creativezenxfi2, vibe500, ipodmini2g, ipod4g, creativezenxfi, creativezenxfi3, sansaview, ipodcolor, creativezenxfistyle, samsungypz5, sansafuzeplus, iriverh10_5gb, tatungtpj1022, gigabeats, faketarget, samsungyh820, gogearhdd1630, samsungyh925, ipodmini1g, ipodvideo, creativezenmozaic, sonynwze370, creativezen, gogearsa9200, gogearhdd6330, sonynwze360, sansae200, mrobe100, iriverh10, creativezenv, ipodnano1g, samsungyh920 USB Driver-wise, it should be noted that this patch requires some slight changes: - proper blocking on control OUT transfers, to make sure the data is received *before* using it, the usb_core should probably use that too - drivers can now support interface alternate settings - drivers can be notified of completion by a new fast handler, which is called directly from the driver; this is is necessary for isochronous transfers because going through the usb queue is way too slow Designware changes: - enable for USBOTG_DESIGNWARE - set maxpacketsize to 1023 for ISO endpoints Change-Id: I570871884a4e4820b4312b203b07701f06ecacc6
