[PATCH v2 1/3] dt-bindings: pinctrl: Add support for Amlogic A4 SoCs

From: Xianwei Zhao via B4 Relay
Date: Mon Oct 14 2024 - 05:06:22 EST


From: Xianwei Zhao <xianwei.zhao@xxxxxxxxxxx>

Add the new compatible name for Amlogic A4 pin controller, and add
a new dt-binding header file which document the detail pin names.
