Since this is a very substantial proportion of the driver move the definitions of these controls into a new wm_hubs module which allows them to be shared between the two.

The WM8776 is a high performance, stereo audio CODEC with five channel input selector. The WM8776 is ideal for surround sound processing applications for home hi-fi, DVD-RW and other audio visual equipment. This driver implements support for most WM8776 features - currently the ADC automatic level control/limiter functionality is omitted. Signed-off-by: NMark Brown <broonie@opensource.wolfsonmicro.com>

This patch adds support for Conexant CX20442-11 voice modem codec, suitable for use by the ASoC board driver for Amstrad E3 (Delta) videophone. Related sound card driver will follow. This codec is an optional part of the Conexant SmartV three chip modem design. As such, documentation for its proprietary digital audio interface is not available. However, on Amstrad Delta board, thanks to Mark Underwood who created an initial, omap-alsa based sound driver a few years ago[1], the codec has been discovered to be accessible not only from the modem side, but also over the OMAP McBSP based CPU DAI. Thus, the driver can be used by any sound card that can access the codec DAI directly. The DAI configuration parameters (sample rate and format, number of channels) has been selected out empirically for best user experience. The codec analogue interface consists of two pairs of analogue I/O pins: speakerphone interface or telephone handset/headset interface. Furthermore, it seams to provide two operation modes for speakerphone I/O: standard and advanced, with automatic gain control and echo cancelation. Even if the codec control interface is unknown and not available, all those interfaces and modes can be selected over the modem chip using V.253 commands. The driver is able to issue necessary commands over a suitable hw_write function if provided by a sound card driver. Otherwise, the codec can be controlled over the modem from userspace while inactive. Even if nothig is known about the codec internal power management capabilities, DAPM widgets has been used to model the codec audio map. Automatically performed powering up/down of those virtual widgets results in corresponding V.253 commands being issued. Some driver features/oddities may be board specific, but I have no way to verify that with any board other than Amstrad Delta.

The WM8960 is a low power, high quality stereo codec designed for portable digital audio applications. Stereo class D speaker drivers provide 1W per channel into 8W loads. Guaranteed low leakage, excellent PSRR and pop/click suppression mechanisms enable direct battery connection for the speaker supply. The device also integrates a complete microphone interface and a stereo headphone driver. External component requirements are drastically reduced as no separate microphone, speaker or headphone amplifiers are required. Advanced on-chip digital signal processing performs automatic level control for the microphone or line input. Stereo 24-bit sigma-delta ADCs and DACs are used with low power over-sampling digital interpolation and decimation filters and a flexible digital audio interface. The master clock can be input directly or generated internally by an onboard PLL, supporting most commonly-used clocking schemes. This driver was originally written by Liam Girdwood, with substantial subsequent additions and updates for feature completeness and changes in the ASoC framework from me.

The WM8988 can operate as a master or a slave, with various master clock frequencies including 12 or 24MHz for USB devices, or standard 256fs rates like 12.288MHz and 24.576MHz. Different audio sample rates such as 96kHz, 48kHz, 44.1kHz are generated directly from the master clock without the need for an external PLL.

Update the CS4270 codec driver to allow applications to use the mixer to control Digital Loopback, Soft Ramp, Zero Cross, Popguard, and Auto-Mute. Soft Ramp, Zero Cross, and Auto-Mute are disabled by the driver when it first initializes the hardware, but these features either don't work or interfere with normal ALSA behavior. However, they can now be re-enabled by an application if desired. Remove CONFIG_SND_SOC_CS4270_HWMUTE and always allow ASoC to control the mute bits. The driver previously and erroneously assumed that these bits control only external muting circuitry, but they also control internal muting circuitry, so they should always be used.

For codecs that have both SPI and I2C support we need to ensure that we don't try to make the codec driver built in when I2C is modular since that won't link. Do this by creating a helper variable which uses conditional defaults to pick up the correct value for all combinations. We don't need to do anything special for I2C-only codecs since a conditional select passes on the full value for a tristate.

The TLV320AIC26 Kconfig option is unusual in that it supports the OpenFirmware machine driver which doesn't have a hard binding to the codec driver but discovers the codec via the device tree.
