Subject: [PATCH v8 0/3] Add single core R5F IPC for AM62 SoC family             

AM62 SoC family don't have a multicore R5F cluster,                             
instead they have a single core R5F.                                            
This enables IPC support with single core R5F for AM62                          
family of SoCs.

While at it, also simplify the cluster mode setting usage
by using soc_data specific checks only at probe.

Devarsh Thakkar (3):
  remoteproc: k3-r5: Simplify cluster mode setting usage
  dt-bindings: remoteproc: ti: Add new compatible for AM62 SoC family
  remoteproc: k3-r5: Use separate compatible string for TI AM62x SoC
    family
