WM9081_BIAS_ENA is the bit[1] of WM9081_BIAS_CONTROL_1 register (05h).

This initial conversion just moves the register init, regulator acquisition
and device verification out to the I2C probe(). Movement of other parts of
the driver like the GPIO and beep generation code will follow.

Actually pretty straightforward.
Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

Now that the WM8996 driver is using the regmap API for register I/O we no
longer need the ASoC card to be active in order to interact with the chip.
In order to be more idiomatic for Linux move most of the existing probe()
function out into the I2C probe() function prior to registration with ASoC.

The IRQ and GPIO init will be moved separately as these are slightly more
involved.

The thermal shutdown support in wm_hubs devices is tied to the speaker
drivers (which are the only high power subsystems within the device).
Ensure minimal current usage when the thermal shutdown support is not
required by disabling the circuit when the speaker drivers are powered
down.

Disable the thermal shutdown circuits for headphone and speaker when the
relevant outputs are not enabled in order to save current in idle modes.

The WM9081 thermal shutdown is only effective when the speaker output is
enabled so disable it when that is not in use for a small current saving.

Having a separate list for amps is a little confusing now the official
driver model for them is the same as for other CODECs so let's sort them
into the CODEC list, but only do this for those that are actual CODEC
drivers so it's easier to remember which ones need updating.
