Subject: [PATCH v1 0/2] power: reset: Add Toradex Embedded Controller

From: Francesco Dolcini <francesco.dolcini@...adex.com>

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@dolcini.it/, 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.
