+Subject: [PATCH] sunxi: Fix 2nd usb controller on sun4i/sun7i no longer
+ working
+
+The 2nd usb controller on sun4i/sun7i has its base address 0x8000
+bytes from the 1st one, rather then 0x1000. Also the ahb clk gates
+are interleaved with the ohci clk-gates introducing a hole between
+the clks for usb1 and usb2.
+
+Signed-off-by: Hans de Goede <hdegoede@redhat.com>
+Acked-by: Ian Campbell <ijc@hellion.org.uk>
