I've added the patch to my wip dts branch on github - which will move to 
kernel.org after -rc1

In the future for v2 and onwards patches, please provide a changelog in the 
comment section (after the "---"), so people can see what changed, like:

changes since v1:
- declare i2s nodes separately on rk3066 and rk3188 as the controllers differ

This doesn't get into the kernel itself, but is helpful for people reviewing 
the patch.
