NXP's TFA98xx (now part of Goodix) are fairly popular speaker amplifiers
used in many smartphones and tablets. Most of them are sold as "smart
amplifiers" with built-in "CoolFlux DSP" that is used for volume control,
plus a "sophisticated speaker-boost and protection algorithm".

Unfortunately, they are also almost entirely undocumented. The short
datasheets (e.g. [1] for TFA9897) describe the available features,
but do not provide any information about the registers or how to use
the "CoolFlux DSP".

The amplifiers are most often configured through proprietary userspace
libraries. There are also some (rather complex) kernel drivers (e.g. [2])
but even those rely on obscure firmware blobs for configuration (so-called
"containers"). They seem to contain different "profiles" with tuned speaker
settings, sample rates and volume steps (which would be better exposed
as separate ALSA mixers).

The format of the firmware files seems to have changed a lot over the time,
so it's not even possible to simply re-use the firmware originally provided
by the vendor.

Overall, it seems close to impossible to develop a proper mainline driver
for these amplifiers that could make proper use of the built-in DSP.

This commit implements a compromise: At least the TFA1 family of the
TFA98xx amplifiers (usually called TFA989x) provide a way to *bypass*
the DSP using a special register sequence. The register sequence can be
found in similar variations in the kernel drivers from lots of vendors
e.g. in [3] and was probably mainly used for factory testing.

With the DSP bypassed, the amplifier acts mostly like a dumb standard
speaker amplifier, without (hardware) volume control. However, the setup
is much simpler and it works without any obscure firmware.

This driver implements the DSP bypass combined with chip-specific
initialization sequences adapted from [2]. Only TFA9895 is supported in
this initial commit. Except for the lack of volume control I can not hear
any difference with or without the DSP, it works just fine.

This driver allows the speaker to work on mainline Linux running on the
Samsung Galaxy A3/A5 (2015) [TFA9895] and Alcatel Idol 3 [TFA9897].
TFA9897 support will be added in separate patch set later.

Convert the arizona extcon driver into a helper library for direct use
from the arizona codec-drivers, rather then being bound to a separate
MFD cell.

Note the probe (and remove) sequence is split into 2 parts:

1. The arizona_jack_codec_dev_probe() function inits a bunch of
jack-detect specific variables in struct arizona_priv and tries to get
a number of resources where getting them may fail with -EPROBE_DEFER.

2. Then once the machine driver has create a snd_sock_jack through
snd_soc_card_jack_new() it calls snd_soc_component_set_jack() on
the codec component, which will call the new arizona_jack_set_jack(),
which sets up jack-detection and requests the IRQs.

This split is necessary, because the IRQ handlers need access to the
arizona->dapm pointer and the snd_sock_jack which are not available
when the codec-driver's probe function runs.

Note this requires that machine-drivers for codecs which are converted
to use the new helper functions from arizona-jack.c are modified to
create a snd_soc_jack through snd_soc_card_jack_new() and register
this jack with the codec through snd_soc_component_set_jack().

The CS4234 is a highly versatile CODEC that combines 4 channels of
high performance analog to digital conversion, 4 channels of high
performance digital to analog conversion for audio, and 1 channel of
digital to analog conversion to provide a nondelayed audio reference
signal to an external Class H tracking power supply.

DAC5 is only supported as a 5th audio channel. Tracking Power Supply
mode is not currently supported by the driver.

In DSP_A mode the slots for DAC1-4 and optionally DAC5 can be set.
The codec always claims 4 slots for DAC1-4 and these must be in the
same nibble of the mask. The codec has a fixed mapping for ADC slots.

In I2S/LJ modes the codec has a fixed mapping for DAC1-4 and ADC1-4.
DAC5 is not available in these modes.

The MCLK source must be preset to a valid frequency before probe()
because it must be running all the time the codec is out of reset.

The VA_SEL bit will be set automatically to 3.3v or 5v during probe()
based on the reported voltage of the regulator supplying VA.

i.e. it moves code around with the minimal required renaming
and changes.
