sys/dev/fdt : rkpciephy.c
Log message:
Add support for the RK3588 PCIe3 PHY to rkpciephy(4). The PHY controls
4 lanes that can be routed to 4 of the 5 PCIe controllers in the following
configurations.
Either all 4 lanes go to the x4 controller, then the other 3 controllers
stay disabled. If those are split, lane 0 goes to the x4 controller and
lane 2 goes to the x2 controller. Lane 1 now either goes to the x4 one
to build a x2, or it gets routed to a x1 controller. Lane 3 also either
goes to the x2 one to build a x2, or it gets routed to a x1 controller.
If lanes 1 or lane 3 are configured, they are routed towards the PCIe3 PHY
instead of the Combo PHY.
