We have soc-dai.c today. DAI related functions
should be implemented in it.
These patches are v2 of doing it.

2.17.1

If one of the two is a loadable module, the combined driver must
not be built-in:

aarch64-linux-ld: sound/soc/codecs/rt5682.o: in function `rt5682_sdw_hw_free':
rt5682.c:(.text+0xb34): undefined reference to `sdw_stream_remove_slave'
aarch64-linux-ld: sound/soc/codecs/rt5682.o: in function `rt5682_sdw_hw_params':
rt5682.c:(.text+0xe78): undefined reference to `sdw_stream_add_slave'

In particular, the soundwire driver must not be built-in if
CONFIG_I2C=m.

ifdefs are hard, and in this driver the suspend/resume functions are
the only callers of some other helpers that trigger a harmless warning
when CONFIG_PM is disabled:

sound/soc/fsl/fsl_easrc.c:1807:12: warning: 'fsl_easrc_get_firmware' defined but not used [-Wunused-function]
 1807 | static int fsl_easrc_get_firmware(struct fsl_asrc *easrc)

  303 | static int fsl_easrc_resampler_config(struct fsl_asrc *easrc)

Remove the #ifdef and just mark the callers as __maybe_unused to
suppress the warnings altogether.

Merge series "Kconfig updates for DMIC and SOF HDMI support" from Ranjani Sridharan <ranjani.sridharan@linux.intel.com>:

This series provides the following updtes to the Intel machine driver
Kconfig:

1. The first patch adds the explicit dependency on GPIOLIB when
SND_SOC_DMIC is selected.

2. SND_SOC_SOF_HDA_AUDIO_CODEC is required for using the legacy
HDA codec driver for HDMI support in SOF. The last 3 three patches
make the required changes to account for this.

Libin Yang (3):
  ASoC: intel: add depends on SND_SOC_SOF_HDA_AUDIO_CODEC for common
    hdmi
  ASoC: sof-sdw: remove CONFIG_SND_SOC_SOF_HDA_AUDIO_CODEC condition
  ASoC: sof_pcm512x: remove CONFIG_SND_HDA_CODEC_HDMI condition

2.17.1

The machine driver bdw-rt5650 (for Google buddy) supports 2 or 4-channel
recording while other two drivers support only 2-channel recording. HW
constraints are implemented to reflect the hardware limitation on BDW
platform.

Changes since v1:
- Change the patch title.
- Remove the DUAL_CHANNEL and QUAD_CHANNEL macros which are too obvious.
- Follow the naming convertion, using 'bdw_rt5650_' and 'bdw_rt5677_' to
  name startup functions.
- Refine the comments in startup functions.
- Redesign the bdw_rt5650_fe_startup() function for readability.
- Add an assignment to initialize runtime->hw.channels_max variable.

Brent Lu (3):
  ASoC: bdw-rt5677: add channel constraint
