From 4bfeea6ec1c0241a6c856ed1694a72a8cbaa8494 Mon Sep 17 00:00:00 2001 From: Mario Limonciello Date: Wed, 9 Apr 2025 23:36:57 -0500 Subject: [PATCH] thunderbolt: Use wake on connect and disconnect over suspend Wake on connect is useful for being able to wake up a suspended laptop without opening the lid by plugging into a dock. Add the default policy to the USB4 router when wakeup is enabled for the router. Behavior for individual ports can be controlled by port wakeup settings.
