Most new Qualcomm WCD codecs support MBHC(Multi Button Headset Control) via ADC. This patchset adds support to Common parts of this MBHC support so that WCD codecs need not duplicate them. To do that codec exposes set of register fields and callbacks to this common driver to control it. Signed-off-by:

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.

But on some platforms ESD voltage will affect it causing test to fail, especially with CTIA headset type. For different hardware setups, a designer might want to tweak default behavior.

cs42l42 does not support standard burst transfers so the use_single_read and use_single_write flags must be set in the regmap config. Because of this bug, the patch: commit 0a0eb567 ("ASoC: cs42l42: Minor error paths fixups") broke cs42l42 probe() because without the use_single_* flags it causes regmap to issue a burst read. However, the missing use_single_* could cause problems anyway because the regmap cache can attempt burst transfers if these flags are not set.
