From 5adaa1a8c08839617e5a6385fe05a8baa63e355f Mon Sep 17 00:00:00 2001 From: Yixun Lan Date: Fri, 2 Jan 2026 15:00:23 +0800 Subject: [PATCH] dt-bindings: pinctrl: spacemit: add K3 SoC support Add new compatible string for SpacemiT K3 SoC, the pinctrl IP shares almost same logic with previous K1 generation, but has different register offset and pin configuration, for example the drive strength and schmitter trigger settings has been changed.
