79ed18d9ec arm64: tegra: Sort nodes by unit-address, then alphabetically
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.

501c9e7ca6 arm64: tegra: Update console for Jetson Xavier and Orin
The Tegra Combined UART (TCU) is the default serial interface for Jetson
Xavier and Orin platforms and so update the bootargs for these platforms
to use the TCU.

2f477ee3ed Revert "arm64: dts: tegra: Fix boolean properties with values"
This reverts commit 1a67653de0, which caused a boot regression.

The behavior of the "drive-push-pull" in the kernel does not
match what the binding document describes. Revert Rob's patch
to make the DT match the kernel again, rather than the binding.

arm64: dts: tegra: Fix boolean properties with values
Boolean properties in DT are present or not present and don't take a value.
A property such as 'foo = <0>;' evaluated to true. IOW, the value doesn't
matter.

It may have been intended that 0 values are false, but there is no change
in behavior with this patch.

bb05e11fff arm64: tegra: Fix mmc0 alias for Jetson Xavier NX
There are two variants of the Jetson Xavier NX platform; one has an
eMMC and one as a micro SD-card slot. The SDHCI controller used by
each variant is different, however, the current device-tree for both
Xavier NX boards have the same SDHCI controller defined as 'mmc0' in
the device-tree alias node. Fix this by correcting the 'mmc0' alias
for the SD-card variant.

1cab0a51f6 arm64: tegra: Prepare for supporting the Jetson Xavier NX with eMMC
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.
