From 34d401a1910dde53356fa5ac03649085fd20e5e3 Mon Sep 17 00:00:00 2001 From: Piyush Mehta Date: Mon, 19 Jun 2023 16:20:32 +0530 Subject: [PATCH] dt-bindings: usb: dwc3: Add interrupt-names property support for wakeup interrupt The hibernation feature enabled for Xilinx Versal NET SoC in DWC3 IP. As the DWC3 IP supports the hibernation feature, to handle the wakeup or hibernation interrupt, add host mode "wakeup" interrupt-names optional property in the binding schema to capture remote-wakeup and connect/ disconnect event in the hibernation state and increased maxItems to 4 for the interrupts and interrupt-names property. We have a dedicated IRQ line specifically for the hibernation feature. When the "wakeup" IRQ line is triggered, it initiates a hibernation interrupt, causing the system to wake up from the hibernation state.
