From 19040e562640fa3a59fbf9ce98f201bf4d2d82d8 Mon Sep 17 00:00:00 2001 From: Ryan Chen Date: Mon, 22 Sep 2025 13:20:42 +0800 Subject: [PATCH] dt-bindings: usb: uhci: Add reset property The UHCI controller on Aspeed SoCs (including AST2700) requires its reset line to be deasserted before the controller can be used. Add an optional "resets" property to the UHCI device tree bindings to describe the phandle to the reset controller. This property is optional for platforms which do not require explicit reset handling.
