The MT7623A's power domains are the subset of MT7623 SoC's ones. As MT7623 SoC has full features whereas MT7623A is being designed just for router applications. Thus, MT7623A doesn't include those power domains multimedia function belongs to. In order to avoid certain errors undoubtedly happening at registering those power domains on MT7623A SoC using the existing MT7623 SCPSYS driver, it's required to define another setup specifically for MT7623A SoC.
