the patch below contains a number of unlerated changes that want to be split
into multiple ones. So you want 3 separate patches in total.

- add the i2s controller to rk356x.dtso
- add the i2s enablement to the rock3a
  (also please specify where it leads to as in the patch below only enables
   the i2s2_2ch without anything using it)
- add the wifi controller with its nodes,


Regards
Heiko
