Well, you will not get too far with just these files. I am using=20
DTS files available in CAF repository with new Qualcomm clock=20
controller driver and one ugly patch which "port" regulator drivers
to upstream kernel.

USB3.0 patches are not really tested because I can not=20
get one of the PHY clocks up.

USB2.0 driver is working fine with following DTS bindings.
