* drivers: usb: Fix rndis file inclusionDavide Garberi2022-07-27
| | | | | | | | * We can just remove it from CONFIG_USB_F_GSI and keep it in CONFIG_USB_F_QCRNDIS as I can't get the first to build without the second but I can get the second to build without the first * The same thing is for CONFIG_USB_CONFIGFS_RNDIS * Fixes a build error because of the file being included twice Signed-off-by: Davide Garberi <dade.garberi@gmail.com>
* usb: gadget: add f_uac1 variant based on a new u_audio apiAjay Agarwal2018-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new function 'f_uac1' (f_uac1 with virtual "ALSA card") that uses recently created u_audio API. Comparing to legacy f_uac1 function implementation it doesn't require any real Audio codec to be present on the device. In f_uac1 audio streams are simply sinked to and sourced from a virtual ALSA sound card created using u_audio API. Legacy f_uac1 approach is to write audio samples directly to existing ALSA sound card f_uac1 approach is more generic/flexible one - create an ALSA sound card that represents USB Audio function and allows to be used by userspace application that may choose to do whatever it wants with the data received from the USB Host and choose to provide whatever it wants as audio data to the USB Host. f_uac1 also has capture support (gadget->host) thanks to easy implementation via u_audio. By default, capture interface has 48000kHz/2ch configuration, same as playback channel has. f_uac1 descriptors naming convention uses f_uac2 driver naming convention that makes it more common and meaningful. Comparing to f_uac1_legacy, the f_uac1 doesn't have volume/mute functionality. This is because the f_uac1 volume/mute feature unit was dummy implementation since that driver creation (2009) and never had any real volume control or mute functionality, so there is no any difference here. Since f_uac1 functionality, exposed interface to userspace (virtual ALSA card), input parameters are so different comparing to f_uac1_legacy, that there is no any reason to keep them in the same file/module, and separate function was created.

* usb: gadget: split out audio coreAjay Agarwal2018-12-20
| | | | | | | | | | | | | | | | | | | | | | | | | Abstract the peripheral side ALSA sound card code into a component that can be called by various functions, so the various flavors can be split apart and selectively reused. Visible changes: - add uac_params structure to pass audio paramteres for g_audio_setup - make ALSA sound card's name configurable - add [in/out]_ep_maxpsize - allocate snd_uac_chip structure during g_audio_setup - add u_audio_[start/stop]_[capture/playback] functions This change differs from opensource patch in that it does not modify the UAC2 driver to use u_audio helper file for ALSA sound card support.

* f_qc_rndis: Compile rndis.c if CONFIG_USB_F_QCRNDIS is enabledVijayavardhan Vennapusa2017-03-22
| | | | | | | | | | | | When CONFIG_USB_F_QCRNDIS is enabled to support RNDIS over BAM2BAM to IPA, it needs to compile rndis.c driver as well. Otherwise will see compilation error. Hence compile rndis.c along with f_qc_rndis.c when CONFIG_USB_F_QCRNDIS is enabled. Disable CONFIG_USB_F_GSI as both configs can't be enabled at a time as that would cause compilation errors and warnings seen due to same misc device name registration.

| | | | | | | | | | | | | | This snapshot is taken as of msm-3.18 commit: bf10764e3d1 (Merge "ARM: dts: msm: Update APC MEM ACC settings for msm8920") This USB CCID function driver will be a transport layer between the userspace CCID component and the Windows Host. Data and control commands from the Windows Host will be sent to the userspace component and vice-versa.
