Subject: [PATCH 0/2] soc: ti: k3-ringacc: Add additional register regions

Ringacc on TI K3 SoCs have configuration registers region which is
usually hidden from Linux and configured via Device Manager Firmware
APIs. But certain early SWs like bootloader which run before Device
Manager is fully up would need to directly configure these registers and
thus require to be in DT description.

This add bindings for the cfg region and also adds them to DT files.
Backward compatibility is maintained to existing DT by only mandating
existing regions to be present and this new region as optional.

Nishanth: I am hoping its possible for you to take bindings and DT
via k3-dts-next once reviewed.
