-Subject: [PATCH] phy: usb: Add support for new Synopsys USB controller on the
- 7211b0
-
-The 7211b0 has added the STB XHCI Synopsys controller and it
-will be used instead of the RPi based DWC USB controller. The new
-Synopsys XHCI controller core is the same one that is used on the
-7216, but because of the way the STB USB PHY is used on both the A0
-and B0, some of the PHY control is different.
