Volume 255 corresponding to register value 0, the value 0 is default
value. In regcache_sync(), when the cache value is equal to default
value, this register will be skipped. So volume 255 isn't set to
register successfully.
The correct fix is to add software reset in runtime_resume, but cs42xx8
has no software reset, the hardware reset gpio pin is used by all the
perpherial device in ARD base board. So need to use another method.
In order to fix it, need to cherry-pick two patch from master branch.
Which will sync all the registers include the register which cache value
equal the default value, And remove regcache_mark_dirty().
Add update value of one register to make the cache_dirty if user press
the hardware reset pin on the board, then need to regcache_sync.

bit constraint list
wm8960 just support 8k 11.025k 16k 22.05k 32k 44.1k and 48k sample
rate. Change rate constraint list to support 8k 16k 32k and 48k for
SAI master mode.
After set SAI MCLK frequency to 36864000HZ, SAI master mode can full
support 16 24 and 32 bit word length and 8k 16k 32k, 48k sample rate.
No need to add sample bit constraint list to restrict physical length,
so remove it.

Revert "ENGR00320678 ASoC: cs42xx8: Revert the DAPM routes to the old one"
When PWR is PGA widget, it is used by input route and output rate, there is
a circle route "AINxL -> PWR -> AOUTxL", alsa driver will open this audio
route in kernel boot up, and refcount of pm enable is set to 1 by soc-dapm,
which cause the codec can't enter pm_suspend.
This reverts commit 8256b071de4ce0971f00f819fae3defa44fe892d.

In imx6qp, there is no mega fast. After suspend, but before resume,
there will be spdif interrupt, if set cache only in suspend, then we
can't clear the interrupt, because regmap_write only write to cache.
So the system will hang for the interrupt can't be cleared.

With componentization we no longer necessarily need a snd_soc_codec struct for a
card. Instead of checking if the card's CODEC list is empty just use
card->instantiated to check if the card has been instantiated yet.

detect error
Audio mclk should be enabled early to avoid jack detect error.
It will playback from speaker in the first 2 seconds, then switch to
headphone. Steps to reproduce this issue:
1. plug out headphone and playback a wav.
2. stop playback and wait for at least 5 seconds, then plug in headphone
and playback a wav.
And set TOCLKSEL (bit1 R23) to get faster jack detect response.

The root cause is hardware issue. In imx7d-sdb hdmi, wm8960 use the
same SAI interface. After playback with wm8960, the Frame clock voltage
doesn't become 0v, wm8960 will introduce noise to frame clock.
This patch is a workaround to set wm8960 to slave mode, remove
interference to I2S signal.

According to the wm8958 referance manual, DAC sample rate 44.1k and 48k
are supported for 24 bit word length when it is 'simple' DAC-only
playback modes. But after test, we found that it would get big noise
which can't be eliminated by configuring codec register. It should be
the codec hardward limitation, and we can't support these sample rate.
