The internal analog power and hp Vref of es8326 should always be on to
reduce pop noise. The HP_VOL and HP_CAL are moved to es8326_mute function
so they are turned on at last and turned off at first.
Also, the calibration should be done manually once during start-up
to reduce DC offset on headphone.

The maple tree register cache has now got to feature parity with the
rbtree cache, there are some different tradeoffs made and it should be a
better choice for most modern systems. Convert the Analog Devices
drivers to use the more modern data structure.

The maple tree register cache is based on a much more modern data structure
than the rbtree cache and makes optimisation choices which are probably
more appropriate for modern systems than those made by the rbtree cache. In
v6.5 it has also acquired the ability to generate multi-register writes in
sync operations, bringing performance up to parity with the rbtree cache
there.
Update the adav80x driver to use the more modern data structure.

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:
Series adds support for two boards: es8336 and rt5663. The former is
utilized by some KBL-based tablets whereas the latter unlocks
Chromebooks with rt5663 i2c codecs.
As existing implementation of es8336 (es8316.c) codec driver is not
prepared to cope with KBL-based platforms, couple of small,
clock-related changes precede anything avs-driver related.
The tail of patchset cleans up existing implementation of rt5682.

Merge series from Andy Shevchenko <andriy.shevchenko@linux.intel.com>:
The first three patches moves intlog10() to be available in entire
kernel. The last one removes copy of it in one driver. Besides already
good Lines of Code (LoC) statistics the upcoming users, if any, can
utilize the exported functions.
The series can be routed via ASoC tree (as Mauro suggested).
Note, int_log.h is separated from math.h due to licensing.
I dunno if we can mix two in a single header file. In any
case we may do it later on.

Merge series from Herve Codina <herve.codina@bootlin.com>:
Several weeks ago, I sent a series [1] for adding a potentiometer as an
auxiliary device in ASoC. The feedback was that the potentiometer should
be directly handled in IIO (as other potentiometers) and something more
generic should be present in ASoC in order to have a binding to import
some IIO devices into sound cards.
The series related to the IIO potentiometer device is already applied.
This series introduces audio-iio-aux. Its goal is to offer the binding
between IIO and ASoC.
It exposes attached IIO devices as ASoC auxiliary devices and allows to
control them through mixer controls.
On my system, the IIO device is a potentiometer and it is present in an
amplifier design present in the audio path.

default switch case.
This can lead to returning an incorrect positive value in case of
