[PATCH v4 0/2] i2c: sunxi: add P2WI controller support

[boris.brezillon@free-electrons.com (Boris BREZILLON)]

Hello Wolfram,

No news from you regarding this patch series.

Is there anything you want me to fix ?

Otherwise It would be great to have this series merged, because the PMIC
used on Allwinner's A31 boards are connected through this P2WI bus.

Best Regards,

Boris
