Hi Yong,

Thanks so much, this driver is a great contribution!

Unfortunately the board I'm working with (nanopi neo air) uses the MIPI 
CSI-2 CSI0 interface rather than CSI1. Do you have any plans to support 
the MIPI CSI-2 interface at some point? If not, do you know the scope of 
what would be involved?
