From 589deb6bc2757787f2b15a84017c23839db3bf8e Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Tue, 28 Oct 2025 17:40:49 +0100 Subject: [PATCH 01/17] arm64: dts: qcom: msm8953: Re-sort tlmm pinctrl states Follow the Devicetree Sources Coding Style and sort the pinctrl nodes by the pins property. This makes it simpler to add new pinctrl states in the future.
