From: Stanislav Lisovskiy <[email protected]> Ultrajoiner mode has some new bits and states to be read out from the hw. Lets make changes accordingly.
v2: Fix checkpatch warnings. (Ankit) v3: Add separate functions for computing expected secondary_big/ultrajoiner pipes. (Ankit) v4: Streamline the helpers for ultrajoiner. (Ville) -Add fixup to accommodate PIPED check for ultrajoiner. (Ville) -Add more Ultrajoiner drm_WARNs.
