18710acdee ASoC: tas5086: add DAPM mux controls
The TAS5086 has two muxes, one for connecting I2S inputs to internal
channels, and another one for selecting which internal channel should
be routed to which PWM output pin.

This patch adds DAPM widgets and routes for this driver.

6b36d370ad ASoC: tas5086: open-code I2C transfer routines
In order to support registers of unequal sizes, the I2C I/O has to be
open-coded.

c300d6de53 ASoC: tas5086: use module_i2c_driver to simplify the code
Use the module_i2c_driver() macro to make the code smaller
and a bit simpler.

4fa89346fb ALSA: ASoC: add codec driver for TI TAS5086
This patch adds a driver for TI's TA5086 6-channel PWM processor.

This chip has a very unusual register layout, specifically because the
registers are of unequal size, and multi-byte registers require bulk
writes to take effect. Regmap does not support these kind of mappings.

Currently, the driver does not touch any of the registers >= 0x20, so
it doesn't matter, because the register map is mapped to an 8-bit array.
In case more features will be added in the future that require access
to higher registers, the entire regmap H/W I/O routines have to be
open-coded.
