Nodes in device tree should be sorted by unit-address, followed by nodes
without a unit-address, sorted alphabetically. Some exceptions are the
top-level aliases, chosen, firmware, memory and reserved-memory nodes,
which are expected to come first.
These rules apply recursively with some exceptions, such as pinmux nodes
or regulator nodes, which often follow more complicated ordering (often
by "importance").
While at it, change the name of some of the nodes to follow standard
naming conventions, which helps with the sorting order and reduces the
amount of warnings from the DT validation tools.

The #address-cells and #size-cells properties for the top-level bus were
set to 1 because that was enough to represent the register ranges of all
the IP blocks on that bus. However, most of these devices can do DMA to
a larger address space, so translation of DMA addresses needs to happen
in a 64-bit address space.
Partially this was already done by the memory controller increasing that
address space by setting #address-cells and #size-cells to 2, but a full
DMA address translation would still cause truncation when traversing to
the top-level bus.
Fix this by setting #address-cells = <2> and #size-cells = <2> on the
top-level bus and adjusting all "reg" and "ranges" properties of its
children.
While at it, also move the PCI and GPU nodes back under the top-level
bus where they belong. The were put outside of it to work around this
same problem.

Regulators defined at the top level in device tree are no longer part of
a simple bus and therefore don't have a reg property. Nodes without a
reg property shouldn't have a unit-address either, so drop the unit
address from the node names. To ensure nodes aren't duplicated (in which
case they would end up merged in the final DTB), append the name of the
regulator to the node name.

Extend APE audio support by adding more audio components such as SFC,
MVC, AMX, ADX and Mixer. These components can be plugged into an audio
path and required processing can be done. ASoC audio-graph based sound
driver is used to facilitate this and thus extend sound bindings as
well.
The components in the path may require different PCM parameters (such
as sample rate, channels or sample size). Depending on the pre-defined
audio paths, these can be statically configured with "convert-xxx" DT
properties in endpoint subnode. The support for the rate and channel
conversion is already available in generic audio-graph driver. Sample
size conversion support can be added based on the need in future.
The support is extended for following platforms:
* Jertson TX1
* Jetson Nano
* Jetson TX2
* Jetson AGX Xavier
* Jetson Xavier NX

The current scheme for audio card names is suboptimal because it causes
the automatically generated names (for ID and driver) to be truncated,
which in turn can cause conflicts.
Introduce a new scheme which reuses the board model for the names and
appends the "HDA" and "APE" suffixes for the HDA and APE, respectively.
As a side-effect these suffixes end up being used as the ID of the SoC
sound cards which makes it easy for users to select them when using the
ALSA command-line utilities, for example.
As a separate measure, the driver name for the cards is now set by the
corresponding audio driver (either tegra-hda or tegra-ape), making it a
more useful identifier than the currently normalized card name.

There are two versions of the Jetson Xavier NX system-on-module; one
with a micro SD-card slot and one with an eMMC. Currently, only the
system-on-module with the micro SD-card slot is supported. Before adding
support for the eMMC variant, move the common device-tree parts of the
existing Jetson Xavier NX system-on-module board (p3668-0000) and
reference carrier board (p3509-0000) into include files that can be used
by both Jetson Xavier NX variants.
