Thanks Lijo and Graham. Yes, I know that only some specific ASICs support VR_MEM1 and LIQUID1.
However, the problem is about the design:
1. should we just list those which are commonly supported by all ASICs.
2. Or we list all the possible throttlers and mask out those unsupported for some specific ASICs
