Impedance values are not correct sometimes due to ramp
being controlled by hw. Run detection routine for sometime
and take final value as impedance value to resolve issue.

Aux cable is detected as unsupported sometimes due to it being
detected as cross conn. Increase hph cross conn threshold to 350mV
so that it detects fine.

HPH PA pull down control is set to force ON instead of auto
due of which saturation/noise is observed in headset
playback at highest volumes. Set pull down control
to Auto to fix this issue.

When current source mode is enabled, comparator auto
zeroing should be turned ON by HW. As rouleur codec HW
doesn't do this automatically, add this support
in SW to set the auto zero enable before FSM enable
and reset to auto once FSM is enabled.
Disable surge protection before ADC measurements
and change HPHL and HPHR thresholds while
identifying cross connection for proper
accessory identification.

Current source mode in rouleur does not work
properly leading to issues in button interrupts
and fake electrical removal interrupts.
Enable pull up mode instead of current source
mode to fix these issues. Modify the headset
max vref voltage to 1.7 volts and micbias
calculation logic.

Update PDM watchdog interrupt sequence for rouleur
codec. Add HPH PA gain registers in regmap and update
defaults. Update mic bias register bits and rouleur
version for ADIE RTC to work.

Update HPHL and HPHR sequence to avoid clicks and pops
by setting the LDIV and RDIV values in HD2
coefficients and increasing ramp time.

Add rouleur codec support in bengal machine driver
to create codec entry and invoke mbhc hs detect
functions for respective codecs. Correct the logic
for headset detection pull up current and
volatile registers for digital part of rouleur codec.
