[PATCH v2 0/2] Add C7xv DSP for AM62A

[Hari Nagalla]

AM62A SoC family has a C7xv DSP subsystem with Analytics engine. This
susbystem is intended for deep learning purposes. C7xv is similar to C71
DSPs on K3 J7 SoCs with additional harware accelerators and IP updates
for deep learining.

[PATCH v2 1/2] dt-bindings: remoteproc: k3-dsp: update bindings for AM62A SoCs

[Hari Nagalla]

The TI AM62A SoCs have a C7xv DSP and Analytics engine for deep
learning purposes. The DSP part is similar to the C71x DSP found on
K3 J7 SoCs, but additional hardware accelerators and IP are added to
the subsystem for deep learning.

Compatible info is updated to match AM62A SoCs.

[PATCH v2 2/2] remoteproc: k3-c7x: Add support for C7xv DSP on AM62A SoC

[Hari Nagalla]

From: Jai Luthra <j-luthra@ti.com>

Add support to the K3 DSP remoteproc driver to configure the C7xv
subsystem core on AM62A SoCs. The C7xv susbsytem is based on C71 DSP
with anlytics engine for deep learning purposes. The remoteproc
handling for device management is similar to the C66/C71 DSPs on K3
J7 family SoCs, even though there are additional hardware accelerators
and IP updates to C7xv subsystem.
