* usb: gadget: add f_uac1 variant based on a new u_audio apiRuslan Bilovol2017-06-191-0/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. g_audio can be built using one of existing UAC functions (f_uac1, f_uac1_legacy or f_uac2) Signed-off-by: Ruslan Bilovol <ruslan.bilovol@gmail.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

Lots of good stuff here, after many many many attempts, the kernel finally has a working typeC interface, many thanks to Heikki and Guenter and others who have taken the time to get this merged. It wasn't an easy path for them at all. There's also a staging driver that uses this new api, which is why it's coming in through this tree. Along with that, there's the usual huge number of changes for gadget drivers, xhci, and other stuff. Johan also finally refactored pretty much every driver that was looking at USB endpoints to do it in a common way, which will help prevent any "badly-formed" devices from causing problems in drivers.

MUSB also got support for building all DMA engines in one binary; this will be great for distros. DWC3 now has no trace of dev_dbg()/dev_vdbg() usage. We will rely solely on tracing to debug DWC3. There was also a fix for memory corruption with EP0 when maxpacket size transfers are > 512 bytes. Robert's EP capabilities flags is making EP selection a lot simpler. UDCs are now required to set these flags up when adding endpoints to the framework. Other than these, we have the usual set of miscelaneous cleanups and minor fixes.

| * usb: gadget: rndis: remove the limit of available rndis connectionsAndrzej Pietrasiewicz2015-05-071-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | RNDIS function has a limitation on the number of allowed instances. So far it has been RNDIS_MAX_CONFIGS, which happens to be one. In order to eliminate this kind of arbitrary limitation we should not preallocate a predefined (RNDIS_MAX_CONFIGS) array of struct rndis_params instances but instead allow allocating them on demand. This patch allocates struct rndis_params on demand in rndis_register(). Coversly, the structure is free()'d in rndis_deregister(). If CONFIG_USB_GADGET_DEBUG_FILES is set, the proc files are created which is the same behaviour as before, but the moment of creation is delayed until struct rndis_params is actually allocated. rnids_init() and rndis_exit() have nothing to do, so they are eliminated.

* | Documentation usb serial: fixed how to provide vendor and product idH. Nikolaus Schaller2015-05-071-5/+7
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While trying to test a Cinterion GSM/GPS/3G module I had reconfigured the USB interface by mistake and therefore needed to run a different USB driver than CDC-ACM. It turned out that I need the "usbserial" driver. This file is an official description how to use it: Documentation/usb/usb-serial.txt But it is outdated. The parameters vendor= and product= have been superseded by a /sys interface. Here was the solution: https://bbs.archlinux.org/viewtopic.php?id=175499 insmod usbserial vendor=0x#### product=0x#### becomes (first #### is vendor, second is product) modprobe usbserial echo #### #### >/sys/bus/usb-serial/drivers/generic/new_id This patch changes the documentation file to describe the modern variant. Please note that the old one still works (if compiled as module). Signed-off-by: H.

It's a total of 217 non-merge commits with pretty much everything being touched.

Other than that, a big list of minor cleanups, smaller bugfixes and new features all over the place. Signed-off-by: Felipe Balbi <balbi@ti.com>
