[PATCH v3 0/8] phy-rockchip-inno-usb2: support rk356x usb2phy

[Peter Geis]

Good Afternoon,

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.

Tested-by: Michael Riesch <michael.riesch@wolfvision.net>

[PATCH v3 2/8] dt-bindings: phy: phy-rockchip-inno-usb2: add rk3568 documentation

[Peter Geis]

The rk3568 usb2phy node is a standalone node with a single muxed
interrupt.
Add documentation for it to phy-rockchip-inno-usb2.

This was the best solution I've come up with for this.
I avoided creating another binding since this is such a simple change to
the actual driver and would likely require renaming the existing
binding.
I've tested that this correctly flags if the interrupts are missing or
incorrectly assigned on both rk356x and rk3399.

Thank you Johan and Rob for your constructive feedback.

[PATCH v3 3/8] phy: phy-rockchip-inno-usb2: support #address_cells = 2

[Peter Geis]

New Rockchip devices have the usb phy nodes as standalone devices.
These nodes have register nodes with #address_cells = 2, but only use 32
bit addresses.

Adjust the driver to check if the returned address is "0", and adjust
the index in that case.
