[PATCH v2 0/2] usb: dwc3: Disable susphy during initialization

[Thinh Nguyen <Thinh.Nguyen@synopsys.com>]

We notice some platforms set "snps,dis_u3_susphy_quirk" and
"snps,dis_u2_susphy_quirk" when they should not need to. Just make sure that
the GUSB3PIPECTL.SUSPENDENABLE and GUSB2PHYCFG.SUSPHY are clear during
initialization. The host initialization involved xhci. So the dwc3 needs to
implement the xhci_plat_priv->plat_start() for xhci to re-enable the suspend
bits.

Since there's a prerequisite patch to drivers/usb/host/xhci-plat.h that's not a
fix patch, this series should go on Greg's usb-testing branch instead of
usb-linus.


 Changes in v2:
 - Fix xhci-rzv2m build issue

Thinh Nguyen (2):
  usb: xhci-plat: Don't include xhci.h
  usb: dwc3: core: Prevent phy suspend during init
