From ce885265ef297b074b0cccfae3a929760e8fa6e7 Mon Sep 17 00:00:00 2001 From: Andrew Jeffery Date: Tue, 3 Dec 2019 22:34:03 +1030 Subject: dt-bindings: misc: Document reg for aspeed, p2a-ctrl nodes The P2A controller 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.
