[PATCH 1/2] dt-bindings: clock: qcom: x1e80100-dispcc: Add USB4 router link resets

From: Konrad Dybcio

Date: Tue Nov 18 2025 - 12:33:26 EST


From: Konrad Dybcio <konrad.dybcio@xxxxxxxxxxxxxxxx>

The router link clock branches also feature some reset logic, which is
required to properly power sequence the hardware for DP tunneling over
USB4.

Describe these missing resets.
