Subject: [PATCH 0/5] watchdog: eiois200_wdt: Add EIO-IS200 Watchdog Driver

From: Wenkai <advantech.susiteam@...il.com>

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.
