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.
- add XHCI_SKIP_PHY_INIT quirk for skip PHY management from HCD core.

Changes for v4:
- Address Jun Li's comments for cdns3 core changes [Patch 2]
- Some small fixes for cdns3-imx for CLK_125_REQ bit
- Rebase the latest usb-next

Changes for v3:
Add Jun Li’s reviewed-by [Patch 1 and Patch 6]
Add Mathias’s acked-by [Patch 4-6]
Some wakeup logic improvement [Patch 2]
Add dedicated wakeup interrupt for core, and improve the commit log [Patch]
Fix build error found by kbuild test robot [Patch 3]
Using xhci_plat_priv quirk for skip PHY initialization [patch 7, patch 9]
Some other typo and tiny improvements

Changes for v2:
- 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.
