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). 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. Link to v3: https://lore.kernel.org/all/20240828112713.2668526-1-b-padhi@ti.com/ 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@ti.com/ 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.
