From: Arınç ÜNAL Date: Fri, 17 Mar 2023 21:30:02 +0000 (+0300) Subject: dt-bindings: pinctrl: mediatek: mt8192: rename to mediatek,mt8192-pinctrl X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=0dcf5a56bd93f92665f9e3437843811fd4374355;p=linux.git dt-bindings: pinctrl: mediatek: mt8192: rename to mediatek,mt8192-pinctrl Rename pinctrl-mt8192.yaml to mediatek,mt8192-pinctrl.yaml to be on par with the compatible string and other mediatek dt-binding schemas.
