Subject[PATCH 11/11] arm64: dts: qcom: sm8550: fix USB wakeup interrupt types
Date
The DP/DM wakeup interrupts are edge triggered and which edge to trigger
on depends on use-case and whether a Low speed or Full/High speed device
is connected.

Note that only triggering on rising edges can be used to detect resume
events but not disconnect events.

Fixes: 7f7e5c1b037f ("arm64: dts: qcom: sm8550: Add USB PHYs and controller nodes")
