From 5c2796adb127c6569e14afab8f18f8bc8db58fb1 Mon Sep 17 00:00:00 2001 From: "Rob Herring (Arm)" Date: Thu, 10 Jul 2025 13:07:40 -0500 Subject: [PATCH] dt-bindings: PCI: Convert axis,artpec6-pcie to DT schema Convert the Axis ARTPEC-6/7 PCIe binding to DT schema format. It's a straight forward conversion.
