Hi Vinod

[Peng Ma] Many thanks.

>Btw pls send bindings as patch1 and driver changes as patch2.
[Peng Ma] I don't understand this sentence, Please give me more information.
As I know patch1 is driver changes, patch2 is dts changes, patch3 is binding changes.
You accepted patch1 and patch3, I am puzzled for patch2 and your comments.

Best Regards,
Peng
