Subject: [PATCH 0/3] remoteproc: introduce Arm remoteproc support
Date: Fri,  1 Mar 2024 16:42:24 +0000	[thread overview]
Message-ID: <20240301164227.339208-1-abdellatif.elkhlifi@arm.com> (raw)

From: Abdellatif El Khlifi <abdellatif.elkhlifi@arm.com>

Some Arm heterogeneous System-On-Chips feature remote processors that can
be controlled with a reset control register and a reset status register to
start or stop the processor.

This patchset adds support for these processors by providing the
following:

1) A remoteproc driver that retrieves the reset registers addresses from
the DT, register a new rproc device with the remoteproc subsystem and
provides the start and stop operations for switching on or off the remote
processor.

The start and stop operations are provided as a data config selected on DT node match.
Currently we are providing support for Corstone-1000 External System (Cortex-M3) [1]
as a remote processor. The driver can be extended to support other remote processors
by adding a data config and custom implementation of the start and stop operations.

2) DT bindings

3) Support control of multiple remote processors at the same time

Cheers,
Abdellatif
