Device tree support for Davinci Machine driver
When the board boots with device tree, the driver will receive card,
codec, dai interface details (like the card name, DAPM routing map,
phandle for the audio components described in the dts file, codec mclk
speed). The card will be set up based on this information. Since the
routing is provided via DT we can mark the card fully routed so core
can take care of disconnecting the unused pins.

The serial-dir array gives this information so there is no need to have the
num-serializer property in DT description.
Just ignore the property in the driver the DTS files can be updated
separately without regression.
Update the documentation at the same time for davinci-mcasp

Makes interrupts property optional as the interrupts are not currently
used by the driver and adds interrupt-names property to name listed
interrupts. Currently know interrupt names are "tx" and "rx".
- Improve tdm-slots propery description
- Improve op-mode property description
- Add pinctrl-names and pinctrl-0 properties
- Remove #address-cells and #size-cells as they are not needed.
- Bracket named interrupts property tuples for uniformity.
- Add missing "for" to serial-dir prop in DT bindings doc.

This patch adds a separate register location for data port registers to
mcasp DT bindings. On am33xx SoCs the McASP registers are mapped
trough L4 interconnect, but data port registers are also mapped trough
L3 bus to a different memory location.

The compatible string of the kirkwood-i2s driver was chosen as
"marvell,mvebu-audio". Using such a compatible string is not a good
idea, since "mvebu" is the name of a large family of SOCs, in which
new, unknown SOCs will be coming in the future. It is therefore
impossible to know what will be evolutions of this hardware block in
the next generations of the SOCs. For this reason, the recommandation
for compatible strings of on-SOCs devices has always been to use the
name of the oldest SOC that has the hardware block. New SOCs that have
an exactly compatible hardware block can reference it using the same
compatible string. See [1], [2] and [3] for various cases were this
suggestion was made, including from Rob Herring, a Device Tree binding
maintainer.
As an example, there are already small differences between current
generations:
* On Kirkwood, only one interrupt is used for audio.
* On Dove, two interrupts are used, one for audio data and one for
error reporting.
In the near future, I'll be adding audio support to Armada 370, which
allows has the same hardware block (but maybe with minor variants).
Therefore, this patch changes the driver to accept
"marvell,kirkwood-audio" and "marvell,dove-audio" as compatible
strings instead of the too-generic "marvell,mvebu-audio". The reason
for the two different compatible strings is the difference in the
number of interrupts used by the two SOCs for audio.
This Device Tree binding has never been part of a Linux kernel stable
release so far, so it can be changed now without breaking backward
compatibility.

This patch adds ac97-slave support.
For ac97, the registers have to be setup earlier than for other ssi
modes because there is some communication with the external device
before streaming. So this patch introduces a fsl_ssi_setup function to
setup the registers for different ssi operation modes seperately.
This patch was tested with imx27-pca100.

Add a Mic Jack widget to the Tegra+RT5640 machine driver, and document
this in the DT binding. This enables the DT to include the Mic Jack in
the audio routing table, and hence enables capture of audio, in addition
to the previously-working playback.

Exynos5420 added support for I2S TDM mode. For this, there are some
register changes in the I2S controller. This patch adds the relevant
register changes to support I2S in normal mode. This patch adds a
quirk for TDM mode and if TDM mode is present all the relevent changes
will be applied.

Samsung has different versions of I2S introduced in different
platforms. Each version has some new support added for multichannel,
secondary fifo, s/w reset control and internal mux for rclk src clk.
Each newly added change has a quirk. So this patch adds all the
required quirks as driver data and based on compatible string from
dtsi fetches the quirks.

Add support for non-dma pcm for imx platforms with imx-pcm-fiq support.
Instead of imx-pcm-audio, in this case imx-pcm-fiq-audio device is added
and the SIER flags are set differently.
We need imx-pcm-fiq for some boards that use an incompatible codec.
imx-pcm-fiq handles those codecs differently and allows to operate with
them. DMA is not possible because some data sent by the codecs, e.g.
wm9712, is not in the datastream. Also some data is mixed up in the
fifos, so that we need to sort them out manually.
