When CONFIG_ENERGY_MODEL=y: cpu cpu0: EM: invalid perf. state: -22 When removing the (incorrect) voltages from the Operating Points Parameters tables, it was assumed they were optional, and unused, when none of the CPU nodes is tied to a regulator using the "cpu-supply" property. This assumption turned out to be incorrect, causing the reported error message. Fix this by re-adding the (correct) voltages. Note that because all voltages are identical, all operating points are considered to have the same efficiency, and the energy model always picks the one with the highest clock rate.
