The MCU is connected via I2C and provides GPIO and watchdog functionality for the SRG-IMX8PL board. The series includes: - Device tree bindings for the MFD, GPIO, and watchdog subsystems - MFD driver that serves as the core driver for the MCU - GPIO driver implementing the GPIO functionality - Watchdog driver for system monitoring - MAINTAINERS entry for the new drivers The drivers follow the standard Linux kernel subsystem patterns, with the MFD driver registering the sub-devices (GPIO and watchdog) which are then handled by their respective subsystem drivers.
