It stands for multi clock gating source. ISP block has a lot of System MMUs and I merged them in a single platform device to control them easier. However it is required to access 2 control registers to gating their clocks. "sysmmu_mc" is prepared for the case that requires 2 clock descriptors for clock gating.

True. I am sorry that I have missed to define it externally. Thank you.
