There was an attempt made by Lucas Stach to develop a VPU blk-ctrl driver to coordinate the power-domains with the GPC driver. Unfortunately, it does appear to hang, so it might not be operating correctly. Lucas, Do you have any idea of stuff I can try to see if the power domain is coming online correctly?
