      ASoC: tegra: fix i2s compilation when !CONFIG_DEBUG_FS · 8abe05c6
      由 Stephen Warren 提交于 
      Commit d4a2eca7 "ASoC: Tegra I2S: Remove dependency on pdev->id" changed
the prototype of tegra_i2s_debug_add, but didn't update the dummy inline
used when !CONFIG_DEBUG_FS. Fix that.

      ASoC: set idle_bias_off=1 for all platform DAPM contexts · 3fec6b6d
      由 Stephen Warren 提交于 
      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.

      [media] tea575x: fix HW seek · bc2b395c
      由 Hans Verkuil 提交于 
      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

      [media] tea575x-tuner: update to latest V4L2 framework requirements · d4ecc83b
      由 Hans Verkuil 提交于 
      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.

      ASoC: pxa-ssp: atomically set stream active masks · 273b72c8
      由 Daniel Mack 提交于 
      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.
