zpos property isn't new in sti driver only the atomic set/get functions are new.
Without those functions atomictest failed to discover any of the other atomic planes properties.
I agree with you, zpos should be generic and I could work with Marek for that
but if this patch isn't merge sti atomic modesetting support will be limited to primary planes...

Oh, another iteration of a driver-private zpos property. This _really_
should be generic, with some consistent cross-driver semantics. Marek from
samsung has started with a patch series for that.
Can you please work together with him, and rebase the sti zpos support on
top of his work? And hold of this patch for now meanwhile?
Also adding Marek.
Thanks, Daniel
