[PATCH v5 0/5] 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

Hari Nagalla (3):
dt-bindings: remoteproc: k3-m4f: Add K3 AM64x SoCs
arm64: dts: ti: k3-am62 : Add M4F remote proc node
arm64: dts: ti: k3-am64 : Add M4F remote proc node

Martyn Welch (2):
remoteproc: k3: Split out functions common with M4 driver
remoteproc: k3-m4: Add a remoteproc driver for M4F subsystem
