Subject: [PATCH 0/8] Add support for AAEON SRG-IMX8PL MCU
Date: Fri, 12 Dec 2025 08:41:03 +0100 [thread overview]
Message-ID: <20251212-dev-b4-aaeon-mcu-driver-v1-0-6bd65bc8ef12@bootlin.com> (raw)
This patch series introduces support for the AAEON SRG-IMX8PL embedded
controller (MCU). 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.
