Instead, each IP block (graphics, media, display) will have their own architecture major.minor versions and stepping ID's which should be read directly from a register in the MMIO space. New hardware programming styles, features, and workarounds should be conditional solely on the architecture version, and should no longer be derived from the PCI device ID, revision ID, or platform-specific feature flags.

One platform could have { arch = 12, rel = 70, step = 1 } and the actual stepping is STEP_B0 but without the translation of the step field would mean STEP_A1.

PM Demand registers are used to communicate display power requirements to the PUnit which would include GV point and mask value. Skip programming GV point and mask values through legacy pcode mailbox interface.
