[PATCH v5 4/5] phy: qcom: m31-eusb2: Set phy type to EUSB2

From: Krishna Kurapati

Date: Thu Jul 23 2026 - 06:54:21 EST


USB controllers like DWC3 are agnostic of the kind of phy (USB2/eUSB2)
connected to it. Set the phy type to EUSB2 to let the controller know
the phy type when queried during its probe.
