Subject: [PATCH 0/3] dt-bindings: dma: ti: k3* : Update optional reg regions

DMAs on TI K3 SoCs have channel configuration registers region which are
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 such configuration regions.  Backward
compatibility is maintained to existing DT by only mandating existing
regions to be present and this new region as optional.
