Hi Marek, Sherry,
we keep the cdns3 node for usb gadget driver, then add a usb host node
for
xhci-imx8 driver in *-uboot.dtsi. so here is no need to change the host driver
compatible.
But the compatible in gadget driver should be changed later.
We should try avoiding ABI breaks in DT.
But the cdns3 usb gaget driver and host driver in different uclass need two dt
nodes to bind with.
And the compatible of the two node cannot be same.
So for gadget driver, the compatible may use "cdns,usb3-1.0.0", for host driver, the
compatible will use "cdns,usb3-1.0.0-host".
What do you think about it?
CCing Jean, since I think he did solve similar topic for his platform.
I've been OOO for a few weeks and didn't look at the whole series.
For this particular issue, the solution I used is to let the wrapper do
the binding job. The name of the driver to use is hard-coded in the
wrapper diver.
This is done in dwc3_glue_bind().
