[linux-yocto] [PATCH 24/25] usb: dwc3: pci: Set enblslpm quirk for Synopsys platforms

[wan.ahmad.zainie.wan.mohamad at intel.com]

From: John Youn <John.Youn at synopsys.com>

Certain Synopsys prototyping PHY boards are not able to meet timings
constraints for LPM. This allows the PHY to meet those timings by
leaving the PHY clock running during suspend.
