Subject: [PATCH AUTOSEL 6.2 15/21] arm64: zynqmp: Enable hs termination flag for USB dwc3 controller

From: Michael Grzeschik <m.grzeschik@...gutronix.de>

[ Upstream commit 32405e532d358a2f9d4befae928b9883c8597616 ]

Since we need to support legacy phys with the dwc3 controller,
we enable this quirk on the zynqmp platforms.
