Compress original dac playback volume to 16 levels according to a table, for
example, 0x37 maps to 0 and 0xfe to 15, which makes it more comfortable for
volume adjustment.

Turn on mic bias earlier to make sure mic bias has time to

With the pop fix and power savings patches, it is possible to bring back the
Jack Function/Speaker Function.
Enable alsa amixer controls Jack Function and Speaker Function. By setting or
unsetting these controls it is now able to turn on or off headphone and speaker
output.

- Turn off DAC and ADC in ANA_POWER reg during idle.
- Turn on zcd and leave it on. Turning if off dynamically
doesn't save power and can cause a small noise artifact.
- Only need to delay 400mSec if state of VAG bit changes.
- Before record, SOC calls digital_mute to unmute, but does
not call digital_mute to mute again after record.
- After record, SOC skips doing the PREPARE state when powering
down. So make sure VAG and mic bias gets turned off in the
STANDBY state if it hasn't already.

Due to the clock source changes, the osc audio clock is disabled by

- This fixes pops that happened after audio playback. These pops
were caused by zcd and DAC being turned off.
- Enable zcd and leave it enabled.
- Turn on DAC early, leave it on.
- We were turning on analog sections during first playback, now turn
them on during initialization instead to avoid delay.

Software workaround for ENGcm06222
If RX and TX are working at same time, and RX is enabled before
TX, tx can't run normally and there will be SSI TX underrun.
The SW workaround is to clear SYN, RE, SSIEN and then re-enable
SYN, RE, TE, SSIEN at the same time.

1. The original ESAI driver treats the mono data as stereo,

The WM8350 is an integrated audio and power management subsystem which
provides a single-chip solution for portable audio and multimedia systems.
The integrated audio CODEC provides all the necessary functions for
high-quality stereo recording and playback. Programmable on-chip
amplifiers allow for the direct connection of headphones and microphones
with a minimum of external components. A programmable low-noise bias
voltage is available to feed one or more electret microphones.
Additional audio features include programmable high-pass filter in the
ADC input path.
This driver was originally written by Liam Girdwood with further updates
from me.

For rev 0x11 of SGTL5000, the VDDD pin is being driven by the

Wav sound plays twice faster than normal when it's format is 24 or 32
bit mono. In ssi normal operating mode, DC=0 provides continuous

The previous commit re-enabled hp_nid setup for IDT92HD73*, but
it's unneeded indeed for Dell laptops that have multiple headphones.
Setting the extra hp_nid results in a non-working "Headpohne" mixer
control. Thus hp_nid should be 0 for these dell models.
Also, the automatic addition of hp_nid should check whether it's
a dual-HP model or not. For dual-HPs, the pins are already checked
by the early workaround.
