Hi,

This series add support for the USB Host controllers available on
RZN1 (r9a06g032) SOC.

These USB Host controllers are PCI OHCI/EHCI controllers located
behind a bridge.

Regards,
Herve

Changes v2:
- Convert bindings to json-schema
- Update clocks description
- Remove unneeded '.compatible = "renesas,pci-r9a06g032"'

Changes v3:
- Remove the unneeded patch that calls clk_bulk_prepare_enable()
- Rework the device tree binding (conversion from .txt and RZ/N1 support)
- Use the RZ/N1 SOCs family only in the driver match compatible string.
- Enable PM and PM_GENERIC_DOMAIN for RZ/N1 and add the missing
  '#power-domain-cells' in sysctrl node.

Changes v4:
- Remove patches related to PM enable and #pwower-domain-cells as they
  will be handle out of this series.
- Add Bob's reviewed-by on patch 1
- Add Geert's reviewed by on patch 1 and 6
- Rename clocks and make the 'resets' property optional on RZ/N1 family
- Reword some commit logs and titles
- Fix dst node location (sort by node names or unit addresses)
- Fix the USB PHY node name
