Both snd_soc_dapm_mux_update_power() and snd_soc_dapm_mixer_update_power() can be called internally within DAPM core (with DAPM mutex held) and externally. Provide some wrappers so that external users of both functions do not have to remember to hold the DAPM mutex.

It has now become necessary to use a DAPM mutex instead of the codec mutex to lock the DAPM operations. This is due to the recent multi component support and forth coming Dynamic PCM updates. Currently we lock DAPM operations with the codec mutex of the calling RTD context. However, DAPM operations can span the whole card context and all components. This patch updates the DAPM operations that use the codec mutex to now use the DAPM mutex PCM subclass for all DAPM ops. We also add a mutex subclass for DAPM init and PCM operations.

This is the first part of a change that is intended to improve ASoC locking protection for DAPM and PCM operations. This part of the series adds a mutex class for the soc_card mutex. The SND_SOC_CARD_CLASS_INIT class is used for card initialisation only whilst the SND_SOC_CARD_CLASS_PCM class is used for the forth coming Dynamic PCM operations. The new mutex classes are required otherwise we will see a false positive mutex deadlock warning between the card initialisation and the PCM operations (something that would never deadlock in real life).

The recent Realtek driver tries to assign an extra input via the headphone plug when only a single input source is found. The code worked on Samsung Q1, but it broke ASUS 1015 where the mic is a digital-mic and only a specific ADC works. This patch fixes the assignment of ADC in the shared mic/hp case. Instead of assuming the single ADC at first, reduce the ADCs after trying to assign both mic and HP pins.

The optimal management of VMID depends on a number of factors which vary dynamically at runtime, for example the connection to a system docking station. In some circumstances it is desirable to keep VMID enabled all the time, in others it is desirable to aggressively power it up and down. Provide a callback allowing machine driver to configure either the normal power up/down mode (WM8994_VMID_MODE_NORMAL) or to maintain VMID even when idle (WM8994_VMID_MODE_FORCE). This callback, wm8994_vmid_mode(), should be called with the CODEC lock. Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

Fix HW seek in TEA575x to work properly: - a delay must be present after search start and before first register read or the seek does weird things - when the search stops, the new frequency is not available immediately, we must wait until it appears in the register (fortunately, we can clear the frequency bits when starting the search as it starts at the frequency currently set, not from the value written) - sometimes, seek remains on the current frequency (or moves only a little), so repeat it until it moves by at least 50 kHz Signed-off-by: NOndrej Zary <linux@rainbow-software.org> Signed-off-by: NHans Verkuil <hans.verkuil@cisco.com> Signed-off-by: NMauro Carvalho Chehab <mchehab@redhat.com>

The tea575x-tuner module has been updated to use the latest V4L2 framework functionality. This also required changes in the drivers that rely on it. The tea575x changes are: - The drivers must provide a v4l2_device struct to the tea module. - The radio_nr module parameter must be part of the actual radio driver, and not of the tea module. - Changed the frequency range to the normal 76-108 MHz range instead of 50-150. - Add hardware frequency seek support. - Fix broken rxsubchans/audmode handling. - The application can now select between stereo and mono. - Support polling for control events. - Add V4L2 priority handling. And radio-sf16fmr2.c now uses the isa bus kernel framework.

PXA's SSP engine fails to take its current channel phase into account when enabling a stream while the engine is already running. This results in randomly swapped left/right channels on either the record or the playback side, depending on which one was enabled first. The following patch fixes this by factoring out the bit field modifications in question to a separate function that pauses the engine temporarily, modifies the bits and kicks it off again afterwards. Appearantly, a transition of SSCR0_SSE syncs both directions properly. The patch has been rolled out to quite a number of devices over the last weeks and seems to fix the issue reliably.

The WM8776 codec driver requires the machine driver to set one of the SND_SOC_DAIFMT_CBx_xxx values. The P1022DS machine driver should be setting SND_SOC_DAIFMT_CBM_CFM, but since that value was zero, no one noticed. Commit 75d9ac46 ("ASoC: Allow DAI formats to be specified in the dai_link"), however, changed the value of SND_SOC_DAIFMT_CBM_CFM from zero to a non-zero value, which means that it now needs to be specifically set by the machine driver. We also set SND_SOC_DAIFMT_NB_NF, for the same reason. Signed-off-by: NTimur Tabi <timur@freescale.com> Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@vger.kernel.org

A previous commit af65cbf2 (ALSA: hdmi: fix printout of SAD sampling rates) fixed the sample rates shown in /proc/asound/cardX/eldY and kernel log to not be entirely wrong. However, a missing rate from the array added in the patch causes HDMI rates 88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz to be shown as 96 kHz, 176.4 kHz, 192 kHz, and 384 kHz, respectively. Fix the reporting by adding the ALSA rate 64 kHz into the conversion array between 48 kHz and 88.2 kHz.
