Looking at the OMAP3 family, there is a single host controller called usbhshost. It has the option of having up to 3 ports. Under usbhshost, there are sub-nodes which have ohci and ehci.
I am trying to port the EHCI controller to DM_USB to pull in the device tree info.
I am fairly certain the ehci controller itself needs to be .id = UCLASS_USB, but I am not sure what class of device should be the upper level node, usbhshost, which contains the ohci and ehci sub-nodes. I need to pull the port info from usbhshost to properly configure the ports.
I am not sure if my question makes sense, but the linux driver doesn't seem to use the same class info as U-Boot, but I'm trying to model the drivers after something similar in linux. Can I use UCLASS_USB as well?
As of right now, by making the ehci node at the root level instead of under usbhshost, and can get the USB to initialize with hard-coded pdata values, but I am not seeing attached devices. I'm still looking into that part, but I want to remove the hard-coded values and replace them with device tree reads as well.
If anyone has started this or has thought I'd love to hear them.
