From 89d6d772f613690eec9540a24b6b0ce60a99540c Mon Sep 17 00:00:00 2001 From: Andrew Jeffery Date: Tue, 3 Dec 2019 22:34:02 +1030 Subject: [PATCH] dt-bindings: pinctrl: aspeed: Add reg property as a hint The pinctrl node sits under a syscon device, and can assume offsets from the base of the syscon based on the compatible. However, for devicetree correctness allow a reg property to be specified, which an associated driver may choose to use to discover associated resources.
