Oliver Schinagl	3b10e6eb68	sun6i: Add new p2wi controller driver ... The A31 uses a new push-pull two wire interface, which features higher transfer speeds (upto 6 MHz) in theory. While the hardware can burst 8 bytes each time, this driver will only see very little use and thus is limited to single byte transmission only.
