Tegra124 adds a number of extra modules into the configlink bus, which
must be taken out of reset before the bus is used. Update the AHUB
driver to know about these extra modules (the AHUB HW module hosts the
configlink bus).

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.

Update all the Tegra DT bindings to require resets/reset-names properties
where the HW module has reset inputs. Remove any entries from clocks or
clock-names that were only required to identify reset inputs, rather than
referring to real clocks.

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.
All Tegra bindings that mention clocks are updated to have consistent
wording and formatting of the clock-related properties.

The IP in DRA7xx is similar to the IP found in TI81xxAM3xxx/AM4xxx type of
SoCs but it is is integrated with sDMA instead of eDMA. The suitable pcm
driver for DRA7xx is the omap-pcm driver which is using dmaengine.
In the driver we can configure both dma related structures used for eDMA and
sDMA. The only thing we need to make sure that we set the correct dma_data
at startup with snd_soc_dai_set_dma_data()

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 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.
