fa09b12dc5 arm: ti: k3: Resync dts files and bindings with Linux Kernel v5.14
This resyncs the dts files for all of the currently in-tree K3
platforms, along with relevant bindings, with the v5.14 Linux Kernel
release.  Of note are that the main-navss/mcu-navss nodes were renamed
to main_navss / mcu_navss and so the u-boot.dtsi files needed to be
updated to match.

Tested on j721e_evm and am65x_evm.

468ec2f3ef remoteproc: k3_r5: Sync to upstreamed kernel DT property names
The K3 R5F remoteproc driver in U-Boot was upstreamed prior to the
equivalent remoteproc driver in the Linux kernel. Some of the DT
properties used in U-Boot got upstreamed using different names
in Linux kernel.

The modified property names include the R5F cluster mode configuration
property "lockstep-mode"; and three different individual R5F core config
properties - "atcm-enable", "btcm-enable" and "loczrama". The property
names were updated as follows:
  lockstep-mode => ti,cluster-mode
  atcm-enable   => ti,atcm-enable
  btcm-enable   => ti,btcm-enable
  loczrama      => ti,loczrama

Update the K3 R5F remoteproc driver, the corresponding binding, and
all the existing usage in AM65x, J721E and J7200 dts files all at
once to use the new properties and to not break any bisectability.

e1c3668594 arm: dts: k3: Add RTI watchdogs
Add DT entries for main domain watchdog0 and 1 instances on the J721e
well as RTI1-based watchdog on the AM65x. RTI0 does not work for this
purpose on the AM65x, so leave it out.

On AM65x, we mark the power-domain as shared because RTI firmware such
as https://github.com/siemens/k3-rti-wdt may request it as well in order
to prevent accidental shutdown of the watchdog.

35f21c3ac6 arm: dts: k3-am65-mcu: Add MCU domain R5F DT nodes
The AM65x SoCs has a single dual-core Arm Cortex-R5F processor
subsystem/cluster (MCU_R5FSS0) within the MCU domain. This cluster
can be configured at boot time to be either run in a LockStep mode
or in an Asymmetric Multi Processing (AMP) fashion in Split-mode.
This subsystem has 64 KB each Tightly-Coupled Memory (TCM) internal
memories for each core split between two banks - ATCM and BTCM
(further interleaved into two banks). There are some IP integration
differences from standard Arm R5 clusters such as the absence of
an ACP port, presence of an additional TI-specific Region Address
Translater (RAT) module for translating 32-bit CPU addresses into
larger system bus addresses etc.

Add the DT node for the MCU domain R5F cluster/subsystem, the two
R5 cores are added as child nodes to the main cluster/subsystem node.
The cluster is configured to run in Split-mode by default, with the
ATCMs enabled to allow the R5 cores to execute code from DDR with
boot-strapping code from ATCM. The inter-processor communication
between the main A72 cores and these processors is achieved through
shared memory and Mailboxes.
