Subject: [RFC PATCH 09/16] dt-bindings: pinctrl: mediatek: rt305x: split binding
From: Arınç ÜNAL <arinc.unal@...nc9.com>
The RT3352 and RT5350 SoCs each 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,rt3352-pinctrl.yaml and
mediatek,rt5350-pinctrl.yaml.
