Hi Felipe & Mathias,

In this series, it adds cdns3 runtime PM support as well as some
xhci-plat changes, and verified at NXP i.MX8QM and i.MX8QXP platforms.

Patch 1-3: add main runtime PM support for cdns3 core and imx glue layer
Patch 4-9: add platform data support and two quirks for xhci-plat.c.
- .suspend_quirk for platform special sequence between xhci_bus_suspend
and xhci_suspend.
- skip_phy_initialization for skip PHY management from HCD core.

Changes for v1:
- Add the 1st patch. Without it, the build on the usb-next will fail.
- Change the subject for cover letter a little to reflect all contents.

Peter Chen (9):

Hi Mathias,

Would I get any comments for xhci-plat.c changes?
