ASoC: wm8994: Skip setting of the WM8994_MICBIAS register for WM1811

The WM8994_MICBIAS register is not available in the WM1811 CODEC so skip
initialization of that register for that device.
This suppresses an error during boot:

ASoC: wm8993/wm8994/wm8958: replace codec to component

Now we can replace Codec to Component. Let's do it.

Becase wm8993/wm8994/wm8958 are using wm_hubs feature,
we need to update these all related drivers in same time.
Otherwise compile error/warning happen

wm8993:
xxx_codec_xxx() -> xxx_component_xxx()
.idle_bias_off = 0 -> .idle_bias_on = 1
.ignore_pmdown_time = 0 -> .use_pmdown_time = 1
- -> .endianness = 1
- -> .non_legacy_dai_naming = 1

wm8994:

.ignore_pmdown_time = 0 -> .use_pmdown_time = 1

ASoC: wm_hubs: Allow configuration of MICBIAS power up delay via pdata

Sometimes the analogue circuitry connected to the microphone needs some
time to settle after power up. Allow systems to configure this delay in
the platform data, the driver will then insert the required delay during
power up of paths that involve the microphone.

ASoC: wm_hubs: Cache multiple DCS offsets

Rather than invalidating the cached DCS value every time the headphone
gain changes store multiple values, indexed by gain. This allows the
optimisation we get from the cache to take effect more often.

ASoC: wm_hubs: Factor out class W management

Since the analogue portions of the checks for class W are the same over
all the devices factor out these checks into wm_hubs and while we're at
it also use wm_hubs_dac_hp_direct() to enable class W optimisations on
more paths.

ASoC: wm_hubs: Special case headphones for digital paths in more use cases

The optimisations which we can do with caching the headphone DCS result in
wm_hubs have only been enabled in cases where class W is enabled. However,
there are more use cases which can benefit from the cache, especially with
WM8994 series devices with their more advanced digital routing.

Rather than keying off the class W information from the CODECs have a
check in wm_hubs for a suitable path and use that to determine if we can
deploy our headphone optimisations.

ASoC: wm_hubs: Disable cache of the DC servo calibration for WM1811

The WM1811 DC servo is able to run much faster than previous devices so
the benefit of skipping calibration is not useful.

ASoC: wm_hubs: Improve single ended line output enable performance

The enable of the single ended line outputs on wm_hubs devices performs
better if the output is enabled prior to starting VMID. Since inactive
outputs are held at VMID anyway there is little cost to doing this for
unused outputs. Add callbacks into wm_hubs and keep track of which outputs
are really active so we can disable them once we're active.

ASoC: Store DC offset correction for wm_hubs devices in class W mode

Providing the analogue configuration of the output path remains the same
the DC offset corrected by the DC servo will remain identical so we can
skip the callibration, reducing the startup time for the headphone output.
Implement this for the wm_hubs devices as has been done for several other
CODECs.

Don't do this if we have any analogue paths enabled since offsets may be
being introduced by the analogue paths which could vary outside the
control of the driver.

ASoC: Support second DC servo readback method for wm_hubs

ASoC: Improved wm_hubs headphone handling

Perform DC servo offset calibration using a series update sequence
rather than startup update sequence, tuning the configuration of the
WM8993 DC servo to make best use of this.

Also introduce currently unused data allowing us to correct for
any systematic errors in the DC servo calibration results and an
alternative startup path for the headphone output which performs
better with some chip revisions. The alternative setup sequence is
enabled for WM8993.

ASoC: Factor out shared code from WM8993

The WM8993 analogue control is shared with other devices in the same

driver move the definitions of these controls into a new wm_hubs module
which allows them to be shared between the two.
