[PATCH 0/7] Add C66x & C71x DSP nodes on J721E SoCs

Hi Nishanth, Tero,

The following series adds the base dt nodes for the 2 C66x and 1 C71x
DSP remote processors present in MAIN domain on J721E SoCs, and the
required nodes to boot these successfully on J721E EVM board. The DSP
remoteproc driver and bindings have been merged into 5.9-rc1. The
series uses previously accepted mailbox nodes.

I have validated the IPC functionality using the latest System Firmware.
The series itself is not directly influenced by the SYSFW version, only
the referenced mailbox interrupts properties get modified as part of
the ABI 3.0 changes. These are already handled in a pending pull-request
for 5.9-rc2 [1].

regards
Suman
