This patch implements a device-tree-only CPU DAI driver for Freescale ESAI
controller that supports:

 - 12 channels playback and 8 channels record.
   [ Some of the inner transmitters and receivers are sharing same group of
     pins. So the maxmium 12 output or 8 input channels are only valid if
     there is no pin conflict occurring to it. ]

 - Independent (asynchronous mode) or shared (synchronous mode) transmit and
   receive sections with separate or shared internal/external clocks and frame
   syncs, operating in Master or Slave mode.
   [ Current ALSA seems not to allow CPU DAI drivers to configure DAI format
     separately for PLAYBACK and CAPTURE. So this first version only supports
     the case that uses the same DAI format for both directions. ]

 - Various DAI formats: I2S, Left-Justified, Right-Justified, DSP-A and DSP-B.

 - Programmable word length (8, 16, 20 or 24bits)

 - Flexible selection between system clock or external oscillator as input
   clock source, programmable internal clock divider and frame sync generation.

This patch depends on "ASoC: tegra: use reset framework" to compile,
which is ack'd and slated to go through a (large) topic branch in the
Tegra tree. So, we can either:

a) Merge that Tegra topic branch into the ASoC tree, then apply this.
   Note that I haven't created the topic branch yet, since I'm still
   waiting for DMA dependencies to be applied.

b) Apply this change to the Tegra tree too. This change isn't directly
   related to the changes in the Tegra tree; it just makes use of the new
   reset controller feature that's introduced there.

Update all the Tegra DT bindings to require the standard dmas/dma-names
properties rather than non-standard nvidia,dma-request-selector property.

This is a DT-ABI-incompatible change. It is the second of two changes
required for me to consider the Tegra DT bindings as stable, the other
being the previous conversion to the common reset bindings.

Many of the Tegra DT binding documents say nothing about the clocks or
clock-names properties, yet those are present and required in DT files.
This patch simply updates the documentation file to match the implicit
definition of the binding, based on real-world DT content.

wording and formatting of the clock-related properties.

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.
