- Further work on the dmaengine helpers, including support for
configuring the parameters for DMA by reading the capabilities of the
DMA controller which removes some guesswork and magic numbers fromm
drivers.
- A refresh of the documentation.
- Conversions of many drivers to direct regmap API usage in order to
allow the ASoC level register I/O code to be removed, this will
hopefully be completed by v3.14.
- Support for using async register I/O in DAPM, reducing the time taken
to implement power transitions on systems that support it.

When going to suspend, shut down all channels and re-do the init

We'll need to call code to initialize and reset the codec again at
resume time, so factor it out first.

We need to access the charge_period and start_mid_z values from other
places later, so move them to the private struct.

It turns out that the TAS5086 doesn't like channel start parts to be
empty, and if all channels are configured to Mid-Z, part 1 has to be
used.

The TAS5086 has two alternative modes to start its PWM channels, Mid-Z
and Low-Z. Which one to use depends on how the PWM power stages are
connected to the TAS5086.
This patch adds 6 optional boolean properties to the DT bindings of the
driver which allow the user to configure each individual channel to the
Mid-Z scheme, and leaves all the others to the default (Low-Z).

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.

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.
