From a4c54f830da86294b8cd7137f686c6d8aa62417c Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Tue, 8 Nov 2022 15:23:56 +0100 Subject: [PATCH] dt-bindings: pinctrl: qcom,ipq8074: convert to dtschema Convert Qualcomm IPQ8074 pin controller bindings to DT schema. Keep the parsing of pin configuration subnodes consistent with other Qualcomm schemas (children named with '-state' suffix, their children with '-pins').
