Hello All,
The K3 J722S SoCs have one single-core Arm Cortex-R5F processor in each
of the WAKEUP, MCU and MAIN voltage domain, and two C71x DSP subsystems
in MAIN voltage domain. Thus, this series adds the DT Nodes for the
remote processors to add support for IPC.
This series also enables IPC on the J722S-EVM platform based on the
above SoC by adding the mailbox instances, shared memory carveouts and
reserving the conflicting timer nodes (as they are used by remoteproc
firmware).
v5: Changelog:
- Collected Reviewed-by tags from Udit and Andrew given in v4 version
of patch ("arm64: dts: ti: k3-j722s-main: Add R5F and C7x remote
processor nodes")
* Udit
1) Updated commit message to correctly reflect the host core name (A53
not A72) in patch "arm64: dts: ti: k3-j722s-evm: Enable Inter-Processor
Communication"
2) Updated mbox DT node label and name to "mbox_wkup_r5_0" from
"mbox_r5_0" for clarity in patch "arm64: dts: ti: k3-j722s-evm: Enable
Inter-Processor Communication"

v4: Changelog:
* Nishanth:
1) Fixed DT node properties order to put standard properties before vendor
specific properties in patch "arm64: dts: ti: k3-j722s-main: Add R5F
and C7x remote processor nodes"
2) Put "status" property at the end in extended DT nodes and preceded
child nodes with a single blank line wherever applicable in patch
"arm64: dts: ti: k3-j722s-evm: Enable Inter-Processor Communication"
following kernel DTS coding style.

https://lore.kernel.org/all/20240828112713.2668526-1-b-padhi@xxxxxx/
v3: Changelog:
1) Reserved conflicting Timer Nodes in k3-j722s-evm.dts file to avoid remotecore
boot failures.
Link to v2:
https://lore.kernel.org/all/20240612112259.1131653-1-b-padhi@xxxxxx/
v2: Changelog:
1) Addressed Andrew's comments to refactor remotecore nodes into
k3-j722s-main.dtsi file.
2) Squashed Patch 2 and 3 from V1 into Patch 2 in V2 as they were doing
the same logical thing.
3) The DTBs check warnings from V1 are automatically fixed after a
dt-binding patch[0] was merged in linux-next.
