This is a note to let you know that I've just added the patch titled
usb: dwc3: pci: Set enblslpm quirk for Synopsys platforms
to my usb git tree which can be found at
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git
in the usb-next branch.
The patch will show up in the next release of the linux-next tree

Subject: usb: dwc3: pci: Set enblslpm quirk for Synopsys platforms
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.
