This is a stack of changes for 5.1 (if I'm not already too late). The bulk of the changes implement a better GMU reset sequence using the new gpucc power domain added in 5.0. If a GMU fault occurs during runtime we try to do a standard GPU recovery and if the fault happens during GMU start then try to fail somewhat gracefully than BUG_ON. There will be a DT change to go along with this, but we can send that along after the core code is merged. The downside for not having the domain properly listed is that the runtime reset sequence probably won't work which is no worse than it is today.
