Thermal zones will follow in a separate series once this one is applied. Tested on the STM32MP257F-DK. Temperature sensor 1 follows the CPU load. Two voltage monitor channels, in0 and in2, read about 815 mV. The other 14 read 1 mV. Questions for ST: - The process detector and voltage monitor blocks are not in the reference manual. Are they at offsets 0x180 and 0x400, as found on the board? The downstream kernel places the process detector at 0x200, where no register responds on the DK. - Which supplies are connected to the voltage monitor channels? With this information, moortec,vm-active-channels could be added.
