* ALSA: snd-usb-usx2y: remove bogus frame checksDaniel Mack2013-10-022-25/+4
| | | | | | | | | | | | | | | | | The frame check in i_usX2Y_urb_complete() and i_usX2Y_usbpcm_urb_complete() is bogus and produces false positives as described in this LAU thread: http://linuxaudio.org/mailarchive/lau/2013/5/20/200177 This patch removes the check code entirely.

All existing drivers have had some level of DAPM support added. - A lot of cleanups in DAPM plus support for maintaining controls in a specific state while a DAPM widget all contributed by Lars-Peter Clausen. - Core helpers for bitbanged AC'97 reset from Markus Pargmann. - New drivers and support for Analog Devices ADAU1702 and ADAU1401(a), Asahi Kasei Microdevices AK4554, Atmel AT91ASM9x5 and WM8904 based machines, Freescale S/PDIF and SSI AC'97, Renesas R-Car SoCs, Samsung Exynos5420 SoCs, Texas Instruments PCM1681 and PCM1792A and Wolfson Microelectronics WM8997. - Support for building drivers that can support it cross-platform for compile test.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver used to assume that the streaming endpoint's wMaxPacketSize value would be an indication of how much data the endpoint expects or sends, and compute the number of packets per URB using this value. However, the Focusrite Scarlett 2i4 declares a value of 1024 bytes, while only about 88 or 44 bytes are be actually used. This discrepancy would result in URBs with far too few packets, which would not work correctly on the EHCI driver. To get correct URBs, use wMaxPacketSize only as an upper limit on the packet size.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | snd_card_register() registers all devices newly added since the last call. However, the playback/capture streams are handled as one ALSA device, so the second /dev device will not be registered if the PCM streams are added in two steps. QUIRK_AUTODETECT caused the probe callback to be called once for each interface, which triggered this problem.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the Android firmware enables the audio interfaces in accessory mode, it always declares in the control interface's baInterfaceNr array that interfaces 0 and 1 belong to the audio function. However, the accessory interface itself, if also enabled, already is at index 0 and shifts the actual audio interface numbers to 1 and 2, which prevents the PCM streaming interface from being seen by the host driver. To get the PCM interface interface to work, detect when the descriptors point to the (for this driver useless) accessory interface, and redirect to the correct one.

* | ALSA: usb-audio: proc: use found syncmaxsize to determine feedback formatTorstein Hegge2013-05-171-11/+11
|/ | | | | | | | | | | | | | | | | | | freqshift is only set for the data endpoint and syncmaxsize is only set for the sync endpoint. This results in a syncmaxsize of zero used in the proc output feedback format calculation, which gives a feedback format incorrectly shown as 8.16 for UAC2 devices. As neither the data nor the sync endpoint gives all the relevant content, output the two combined. Also remove the sync_endpoint "packet size" which is always zero and the sync_endpoint "momentary freq" which is constant. Tested with UAC2 async and UAC1 adaptive, not tested with UAC1 async.

* ALSA: usb-audio: caiaq: fix endianness bug in snd_usb_caiaq_maschine_dispatchEldad Zack2013-04-301-5/+5
| | | | | | | | | | | | | | | | | | | | | | | Current code does this: be16_to_cpu(buf[i * 2] << 8 | buf[(i * 2) + 1]) Which is effectively (neglecting the index): be16_to_cpu(be16_to_cpu(*((u16 *) buf))) This means the int16 in the buffer is not converted at all. Daniel Mack confirmed that the driver works on little endian CPUs, leading to the conclusion that the device-side structure is actually little endian. This changes the code to use le16_to_cpu(). Caught by sparse. Acked-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Eldad Zack <eldad@fogrefinery.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
* ALSA: pcm_format_to_bits strong-typed conversionEldad Zack2013-04-293-5/+6
| | | | | | | | | | | Add a function to handle conversion from snd_pcm_format_t to bitwise with proper typing. Change such conversions to use this function and silence sparse warnings. Signed-off-by: Eldad Zack <eldad@fogrefinery.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
