Hi all, This patch set introduces a concept of sustainable OPP, which then can be used by kernel frameworks or governors for estimating system sustainable system state. This kind of estimation is done e.g. in thermal governor Intelligent Power Allocation (IPA), which calculates sustainable power of the whole system and then derives some coefficients for internal algorithm. The patch set introduces a new DT bindings 'opp-sustainable', with parsing code. It also adds a function (in patch 3/4) which allows device drivers to set directly the sustainable OPP. This is helpful when the device drivers populate the OPP table by themself (example in patch 4/4). The patch set should apply on top of next-20201028.
