Then, at least for this use case, we're talking about voltage, not some unspecified units.In some cases we actually know the voltage of the domain and would want to put some voltage mapping in DT. For example, level 1 is voltage 2V and level 2 is voltage 2.5V.But even in these cases we wouldn't be using the voltage values within the kernel as we will be giving only a performance state to the M3 core, right?
Nope. In these cases we need to set a certain voltage and we do that by requesting it via the M3 core. -- Qualcomm Innovation Center, Inc. is a member of Code Aurora Forum, a Linux Foundation Collaborative Project
