[PATCH v6 1/6] dt-bindings: reset: syscon-reboot: Add reg property

From: Chris Packham
Date: Tue Oct 15 2024 - 19:00:25 EST


The syscon-reboot binding used 'offset' for historical reasons. Having a
reg property is appropriate when these nodes are children of a MMIO bus.
Add a reg property and modify the constraints so that one of 'reg' or
'offset' is expected.
