Hi

I am working on adding USB device tree support for MSM platform.  One of
our chip set has 2 hsusb cores. The first core is configured as otg and
the other core is configured in host only mode (EHCI compliant). Are the
below device node names Okay? Please suggest.
Why do you need to name the speed of the device and the host?  That
doesn't really matter if you plug a low-speed device into that super
speed host controller, right?
Right :-)
I'm not familiar with device tree naming conventions, but is this
something you do for network devices?  If not, I'd not recommend it for
USB controllers either.
I am also not sure about the label names. The reason I would like to
have them in device tree source file is just for readability. One can
easily correlates the device node properties with the label. Say if I
want to change the IRQ number or some property value of 1st instance
HSUSB device controller (while porting a different board), I look for
hsusb0-device.

Thanks,
Pavan
