Merge series from Bard Liao <yung-chuan.liao@linux.intel.com>:
As discussed in [1], ASoC core supports multi codec DAIs
on a DAI link. However it does not do so for CPU DAIs.
So, add support for multi CPU DAIs on a DAI Link by adding
multi CPU DAI in Card instantiation, suspend and resume
functions, PCM ops, stream handling functions and DAPM.
[1]: https://www.spinics.net/lists/alsa-devel/msg71369.html
changes in v5:
- rebase to latest kernel base
Bard Liao (2):
ASoC: Return error if the function does not support multi-cpu
ASoC: pcm: check if cpu-dai supports a given stream
Shreyas NC (4):
ASoC: Add initial support for multiple CPU DAIs
ASoC: Add multiple CPU DAI support for PCM ops
ASoC: Add dapm_add_valid_dai_widget helper
ASoC: Add multiple CPU DAI support in DAPM

ASoC core supports multiple codec DAIs but supports only a CPU DAI.
To support multiple cpu DAIs, add cpu_dai and num_cpu_dai in
snd_soc_dai_link and snd_soc_pcm_runtime structures similar to
support for codec_dai. This is intended as a preparatory patch to
eventually support the unification of the Codec and CPU DAI.
Inline with multiple codec DAI approach, add support to allocate,
init, bind and probe multiple cpu_dai on init if driver specifies
that. Also add support to loop over multiple cpu_dai during
suspend and resume.
This is intended as a preparatory patch to eventually unify the CPU
and Codec DAI into DAI components.

ASoC component open/close and snd_soc_component_module_get/put are called
independently for each component-substream pair, so the logic added in
commit dd03907bf1 ("ASoC: soc-pcm: call snd_soc_component_open/close()

Implement handling of failures directly in soc_pcm_components_open(),
so that any successfully opened components are closed upon error with
other components. This allows to clean up error handling in
soc_pcm_open() without adding more state tracking.

dpcm_path_put() (A) is calling kfree(*list).
The freed list is created by dapm_widget_list_create() (B) which is called

The TLV320ADCx140 parts support Dynamic Range Enhancer (DRE) as defined
in Section 8.3.2 of the data sheets.
The DRE achieves a complete-channel dynamic range as high as 120 dB.
At a system level, the DRE scheme enables far-field, high-fidelity recording
of audio signals in very quiet environments and low-distortion recording in
loud environments.
There are 2 enables for DRE. The first is a global setting that enables
the DRE engine in the device and the other enable is per channel. If
the DRE is enabled globally then either DRE or AGC can be used per each
configured channel. If global DRE is disabled then even setting the DRE
enable bit in the channel config register will have no effect.

Instead of using the I2S divider from the AIU_CLK_CTRL_MORE register we
need to use the I2S divider from the AIU_CLK_CTRL register. This older
register is less flexible because it only supports four divider settings

- i915 codec reports error in HDA codec probe
- HDA codec driver probe fails

The RK3328 reference design uses an external line driver IC as a buffer
on the analog codec output, enabled by the GPIO_MUTE pin, and such a
configuration is currently assumed in the codec driver's direct poking
of GRF_SOC_CON10 to control the GPIO_MUTE output value. However, some
boards wire up analog audio yet use that pin for some other purpose, so
that assumption doesn't always hold. Update this functionality to rely
on an explicit GPIO descriptor, such that it can be managed at the
