These devices provide comprehensive hardware monitoring capabilities including voltage, current, power, and temperature monitoring across multiple channels. The driver implements: - Voltage monitoring for 4 channels - Current monitoring for 4 channels - Power monitoring for 5 channels (including sum) - Temperature monitoring - Error detection and reporting with per-error counters Tested on TI,TPS53830 DDR5 PMICs at I2C addresses 0x4a and 0x4b.
