The following series of patches add support for J721S2 SoC.
Currently, the PSIL source and destination thread IDs for only a few of the
IPs have been added. The remaning ones will be added as and when they are
tested.
The following series of patches are dependent on,

It is runtime dependency, so not an issue.

May I know if this patch series can be applied to next? This series is a
