[PATCH v3 0/2] Add Remoteproc Support for TI's J722S SoCs

[Beleswar Padhi <b-padhi@ti.com>]

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).

v3: Changelog:
1) Reserved conflicting Timer Nodes in k3-j722s-evm.dts file to avoid remotecore
boot failures.

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.
