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.

455f9dddc8 arm: dts: k3-j7200-main: Add support for HS400 and update delay select values for MMCSD subsystems
HS400 speed mode is now supported in J7200 SoC[1]. Therefore add
mmc-hs400-1_8v tag in sdhci0 device tree node.

Also update the delay values for various speed modes supported, based on
the revised january 2021 J7200 datasheet[2].

6239cc8c4e arm: dts: k3-j7200: Sync Linux v5.11-rc6 dts into U-Boot
Sync all J7200 related v5.11-rc6 Linux kernel dts into U-Boot.
MCU R5F nodes are not yet added in Linux kernel yet but were added
in U-Boot. In order to avoid regressions, r5f nodes are kept intact.
These will be added in kernel in future.

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.

3f7e032f70 arm: dts: k3-j7200-main: Add MAIN domain R5F cluster nodes
The J7200 SoCs have 2 dual-core Arm Cortex-R5F processor (R5FSS)
subsystems/clusters. One R5F cluster is present within the MCU
domain (MCU_R5FSS0), and the other one is present within the MAIN
domain (MAIN_R5FSS0). Each of these 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. These subsystems have 64 KB
each Tightly-Coupled Memory (TCM) internal memories for each core
split between two banks - ATCM and BTCM (further interleaved into
two banks). The TCMs of both Cores are combined in LockStep-mode
to provide a larger 128 KB of memory.

Add the DT node for the MAIN domain R5F cluster/subsystem, the two
R5F 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.
