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.
|
