The ipc dai config dai_index is from topology. However, the same dai
config will be applied to all DAIs in the same dai link. We have to
ensure that the ipc dai config's dai_index match to the component's
dai_index.

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':

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:

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

  ASoC: sof-sdw: remove CONFIG_SND_SOC_SOF_HDA_AUDIO_CODEC 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.
