Merge snd_maudio_ftu_create_ctl() and snd_ebox44_create_ctl() into snd_create_std_mono_ctl(). As opposed to the ftu and ebox-44 specific functions, a TLV callback can be specified for controls created by snd_create_std_mono_ctl(). [fixed minor checkpatch.pl warnings by tiwai] Signed-off-by:

Along with the IEC-60958 channel status word, CEA-861 Audio InfoFrames are used in HDMI and DisplayPort to describe the parameters of the audio stream. Hence, drivers for such devices may use these definitions to, for instance, fill a CEA-861 data structure and pass it to a display driver to configure an IP. Signed-off-by:

Implicit feedback is a streaming mode that does not rely on dedicated sync endpoints but uses the information provided by record streams to clock output streams. Now that the streaming logic is decoupled from the PCM streams, this is easy to implement. Signed-off-by:

This patch adds a new generic streaming logic for audio over USB. It defines a model (snd_usb_endpoint) that handles everything that is related to an USB endpoint and its streaming. There are functions to activate and deactivate an endpoint (which call usb_set_interface()), and to start and stop its URBs. It also has function pointers to be called when data was received or is about to be sent, and pointer to a sync slave (another snd_usb_endpoint) that is informed when data has been received. A snd_usb_endpoint knows about its state and implements a refcounting, so only the first user will actually start the URBs and only the last one to stop it will tear them down again. With this sort of abstraction, the actual streaming is decoupled from the pcm handling, which makes the "implicit feedback" mechanisms easy to implement. In order to split changes properly, this patch only adds the new implementation but leaves the old one around, so the the driver doesn't change its behaviour. The switch to actually use the new code is submitted separately. Signed-off-by:

ASoC: fixes for 3.4 A bunch of driver-specific fixes and one generic fix for the new support for platform DAPM contexts - we were picking the wrong default for the idle_bias_off setting which was meaning we weren't actually achieving any useful runtime PM on platform devices.

The ID used for detection of the BenQ R55E actually identifies the Quanta TW3 ODM design, which is also used for the Gigabyte W551 laptop series. Schematics on the internet clearly indicate that the "Port C" (analog input connected to record source #4 and mixer input #4) is unconnected. Playing an audio CD through analog playback (using cdplay from cdtools) produces no sound, even with the mixer input labelled "CD" enabled, and the volume control in the CD drive set to maximum. This indicates the connection is really not present. Signed-off-by:

The ASoC core currently defaults to using STANDBY rather than OFF for idle ASoC platform devices, which causes a permanent pm_runtime_get() on them. This keeps the device active unnecessarily. This can be especially problematic when the ASoC platform device and DAI device are the same device. The distinction between OFF and STANDBY is likely not relevant for ASoC platform drivers, since they aren't analog devices. So, solve this issue by hard-coding idle_bias_off = 1 for all ASoC platform devices. If this turns out to be a problem, this value could be sourced from the snd_soc_platform_driver, similarly to soc_probe_codec(). Note: Prior to this change, this caused a large (10) runtime_active count for the Tegra I2S controller even when not in use, and a leak in that value as streams were started and stopped. This change probably hides a bug. Signed-off-by:
