As I asked for the ad5064 binding document, when would you want to do
this, and why can't the driver decide?

Cheers,

Hi,

sorry my fault. I got confused with an older version of this driver and the 
version that actually made it upstream. This property is not in the upstream 
driver. The patch can safely be ignored and go to /dev/null. Again, sorry 
for noise.
