Subject: [PATCH v5 8/9] pinctrl: mediatek: mt6397: Add MediaTek MT6392

From: Luca Leonardo Scorcia <[email-masked]>
Date: Mon, 20 Apr 2026 22:30:07 +0100

Add support for the MT6392 pinctrl device, which is very similar to
MT6397 with a handful of different property values and its own pins
definition.

Update the MT6397 driver to retrieve device data from the match table and
use it for driver init.
