From: Stephen Boyd Date: Mon, 19 Feb 2024 20:23:23 +0000 (-0800) Subject: dt-bindings: mfd: cros-ec: Add properties for GPIO controller X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=7b79740d42e7535901296f7acbab1043633422e6;p=linux.git dt-bindings: mfd: cros-ec: Add properties for GPIO controller The ChromeOS embedded controller (EC) supports setting the state of GPIOs when the system is unlocked, and getting the state of GPIOs in all cases. The GPIOs are on the EC itself, so the EC acts similar to a GPIO expander. Add the #gpio-cells and gpio-controller properties to the cros-ec binding so that other devices described in DT can get the GPIOs on the EC.
