When the device-tree board file was added for the Tegra234 VDK simulator
it incorrectly used the names 'cbb' and 'sdhci' instead of 'bus' and
'mmc', respectively. The names 'bus' and 'mmc' are required by the
device-tree json-schema validation tools. Therefore, fix this by
renaming these nodes accordingly.

The Jetson Xavier NX board routes UARTA to the 40-pin header and UARTC
to a 12-pin debug header. The UARTs can be used by either the Tegra
Combined UART (TCU) driver or the Tegra 8250 driver. By default, the
TCU will use UARTC on Jetson Xavier NX. Currently, device-tree for
Xavier NX enables the TCU and the Tegra 8250 node for UARTC. Fix this
by disabling the Tegra 8250 node for UARTC and enabling the Tegra 8250
node for UARTA.

Commit ff4c371d2bc0 ("arm64: defconfig: Build ADMA and ACONNECT driver")
enable the Tegra ADMA and ACONNECT drivers and this is causing resume
from system suspend to fail on Jetson TX2. Resume is failing because the
ACONNECT driver is being resumed before the BPMP driver, and the ACONNECT
driver is attempting to power on a power-domain that is provided by the
BPMP. While a proper fix for the resume sequencing problem is identified,
disable the ACONNECT for Jetson TX2 temporarily to avoid breaking system
suspend.
Please note that ACONNECT driver is used by the Audio Processing Engine
(APE) on Tegra, but because there is no mainline support for APE on
Jetson TX2 currently, disabling the ACONNECT does not disable any useful
feature at the moment.

commit 5425fb15d8ee ("arm64: tegra: Add Tegra194 chip device tree")
Tegra194 uses separate SDMMC_LEGACY_TM clock for data timeout and
this clock is not enabled currently which is not recommended.
Tegra194 SDMMC advertises 12Mhz as timeout clock frequency in host
capability register.
So, this clock should be kept enabled by SDMMC driver.

Add the device-tree source files for the Tegra194 Jetson Xavier NX
Developer Kit. The Xavier NX Developer Kit consists of a small form
factor system-on-module (SOM) board (part number p3668-0000) and a
carrier board (part number p3509-0000).
The Xavier NX Developer Kit SOM features a micro-SD card slot, however,
there is also a variant of the SOM available that features a 16GB eMMC.
Given that the carrier board can be used with the different SOM
variants, that have different part numbers, both the compatible string
and file name of the device-tree source file for the Developer Kit is a
concatenation of the SOM and carrier board part numbers.
Based on some initial work by Thierry Reding <treding@nvidia.com>.
