The LT3074 is a single-channel device with basic enable and power-good GPIOs, fewer registers, and fewer functionalities than the LT7182S. Like other PMBus drivers, its GPIOs are not exposed. Here are other PMBus regulators/power modules found in trivial-devices I also used as reference: - infineon,irps5401 - delta,q54sj108a2 Best regards, Cedric
