Subject: [PATCH v3 0/3] TI K3 M4F support on AM64x and AM62x SoCs

The following series introduces K3 M4F remoteproc driver support for
AM64x and AM62x SoC families. These SoCs have a ARM Cortex M4F core in
the MCU voltage domain. For safety oriented applications, this core is
operated independently with out any IPC to other cores on the SoC.
However, for non safety applications, some customers use it as a remote
processor and so linux remote proc support is extended to the M4F core.

See AM64x Technical Reference Manual (SPRUIM2C – SEPTEMBER 2021) for
further details: https://www.ti.com/lit/pdf/SPRUIM2

This series was originally submitted by Hari in Jan 2022. Review
comments were made, however I've been unable to find any further
submissions. I have tried to contact the author and have received no
reply. As we are interested in using this functionality, we have decided
to pick this up and see if we can get it merged.

Hari Nagalla (1):
  dt-bindings: remoteproc: k3-m4f: Add bindings for K3 AM64x SoCs

Martyn Welch (2):
  remoteproc: k4: Split out functions common with M4 driver
  remoteproc: k4-m4: Add a remoteproc driver for M4F subsystem
