Subject: [RFC PATCH 0/9] phy-rockchip-inno-usb2: support rk356x usb2phy

Good Morning,

This is my series to support the usb2 phy devices on the rk356x.
The rk356x phy has a single muxed interrupt and has moved the usb2phy
nodes out of the grf and into their own nodes.
The phy needs to tie back into the grf for register control, similar to
the rv1108.
By moving the phys into their own nodes, they now have full
#address_cells = 2 register addresses, but they still reside below the 32bit
mmio range.

This driver series only supports the host configuration for the rk356x.
I have have tested it on the following:
rk3566 - Pine64 Quartz64 Model A
rk3399 - Pine64 Rockpro64

Please provide feedback and comments as you see fit.

Peter Geis (9):
  dt-bindings: soc: rockchip: add rk3568-usb2phy-grf
  dt-bindings: phy: phy-rockchip-inno-usb2: add rk3568 documentation
  dt-bindings: usb: generic-ohci: increase maximum clocks
  phy: phy-rockchip-inno-usb2: support #address_cells = 2
  phy: phy-rockchip-inno-usb2: support standalone phy nodes
  phy: phy-rockchip-inno-usb2: support muxed interrupts
  phy: phy-rockchip-inno-usb2: add rk3568 support
  arm64: dts: rockchip: add usb2 nodes to rk3568 device tree
  arm64: dts: rockchip: add Quartz64-A usb2 support
