From: Wenkai <advantech.susiteam@xxxxxxxxx> This patch series aims to add support for the Advantech EIO-IS200 Embedded Controller's watchdog timer to the Linux kernel. The EIO-IS200 is a widely used embedded controller, and this series introduces a native driver for its watchdog timer functionality within the Linux ecosystem. Driver Features: - Complete support for the Advantech EIO-IS200 Embedded Controller's hardware watchdog timer. - Seamless integration with the Linux Watchdog framework, enabling standard watchdog functionality. - Flexible configuration options for watchdog timeout and event types. - Module parameters for setting default timeout and event type. - The EIO-IS200 can select special event output pin such as PWRBTN (Power button),SCI (ACPI System Control Interrupt), IRQ, and GPIO Driver Dependencies: - The driver relies on the Linux Multi-Function Device (MFD) framework and related dependencies. - Assumption of the presence of the Advantech eiois200_core MFD core driver.
