So.. is this a no-no? I of course would like to omit this entirely, but SMMUs on sdm630 and friends are REALLY picky.. What seems to happen is that when the driver tries to do things the "standard" way, hypervisor decides to hang the platform or force a reboot. Not very usable. This thing is needed for the platform to even boot properly and one more [1] is required to make mdss work with video mode panels (the fact that CMD-mode panels work is kinda hilarious to me). To be honest, there are even more qcom quirks (of which at least qcom,dynamic and qcom-use-3-lvl-tables are used on 630).. [2] Looking forward to your answers and possibly better solutions.
