Support the TI TAS2552 Class D amplifier.
The TAS2552 is a high efficiency Class-D audio
power amplifier with advanced battery current
management and an integrated Class-G boost
The device constantly measures the
current and voltage across the load and provides a
digital stream of this information.

Currently, the driver places no restrictions on changes that can be
applied to an active FLL. However, it is only possible to change the
input for an active FLL, to change the output the FLL should be stopped
and then recofigured. This patch disallows changes in output frequency
and adds some additional handling to ensure the output remains
consistent across an input transition.

arizona_is_enabled_fll currently returns a bool, but can throw an error.
The error will be basically ignored and we will treat the FLL as already
on. This patch changes the return to be an int and adds error code to
propagate the error up to the callback.

When configuring the FLL we must ensure that the reference clock passed
to the FLL is under a certain limit. This limit was specified
incorrectly in the current code, this patch corrects this. Although the
error will only be encountered in some edge cases.

The check to ensure the Fref frequency is within the bounds for the
current ratio, was placed in the wrong loop. The initial configuration
will always be valid and the loop lowering the ratio will only reinforce
this validity. The check should be on the loop increasing the ratio.
This could on occasion cause an invalid ratio/Fref combination to be
selected.

This problem is well explained by Russell King:
"The sgtl5000 uses a two-stage initialisation process. The first stage
is when the platform driver is probed, where some resources are found
and initialised. The second stage is via the codec driver's probe
function, where regulators are found and initialised using the managed
resource support.
The problem here is that this works fine until the codec driver is
unbound. When this occurs, sgtl5000_remove() is called which is a no-op
as far as the managed resource code is concerned. The regulators remain
allocated, and their pointers in sgtl5000_priv remain valid.
If the codec is now re-probed, it will again try and find the regulators,
which will now be busy. This will fail.
That's not the only problem - if using the LDO regulator, the regulator
is unregistered from the regulator core code, but it still has a user.
When the user is cleaned up (eg, by removing the module) it hits the
free'd regulator, and this can oops the kernel.
This bug was originally introduced by 63e54cd9ca ("ASoC: sgtl5000:
Use devm_regulator_bulk_get()")."
This reverts commit 63e54cd9ca.
Tested on a imx53-qsb board.

This patch adds Realtek ALC286 codec driver.
ALC286 is a dual mode codec, which can run as HD-A or I2S mode.
It is controlled by HD-A verb commands via I2C protocol.
The following is the I/O difference between ALC286 and general I2S codecs.
1. A HD-A verb command contains three parts, NID, VID, and PID.
And an I2S command contains only two parts: address and data.
2. Not only the register address is written, but the read command also
includes the entire write command.
3. rt286 uses different registers for read and write the same bits.
We map verb command to regmap structure. However, we read most registers from
cache to prevent the asymmetry read/write issue in rt286.

The only difference is the lower boundary checking for freq_in.

The k_bp of struct rt5677_pll_code is always false, thus also remove the
