[PATCH v2 0/2] power: reset: Add Toradex Embedded Controller

From: Francesco Dolcini
Date: Mon Apr 14 2025 - 13:15:19 EST


From: Francesco Dolcini <francesco.dolcini@xxxxxxxxxxx>

This series adds support for the Toradex Embedded Controller, currently used on
Toradex SMARC iMX95 and iMX8MP boards.

The EC provides board power-off, reset and GPIO expander functionalities.

We did send an RFC before,
https://lore.kernel.org/all/20250313144331.70591-1-francesco@xxxxxxxxxx/, with
reference to the discussion about implementing this as a MFD, we decided to
just have a power/reset driver, given we do not see a need to expand the
functionalities we already have.


v2: fix commit message
v1: https://lore.kernel.org/lkml/20250407114947.41421-1-francesco@xxxxxxxxxx/
