[RFC PATCH 10/16] dt-bindings: pinctrl: mediatek: mt7620: split binding
From: arinc9 . unal
Date: Wed Feb 22 2023 - 13:41:25 EST
From: Arınç ÜNAL <arinc.unal@xxxxxxxxxx>
The MT7628 and MT7688 SoCs contain different pin muxing information,
therefore, should be split. This can be done now that there are compatible
strings to distinguish them from other SoCs.
Split the schema out to mediatek,mt76x8-pinctrl.yaml.
