[PATCH 0/4] mfd: eiois200: Add core driver for EIO-IS200

[advantech . susiteam]

The EIO-IS200 Series is an embedded controller (EC) used in various
Advantech hardware products, including embedded systems and industrial
computers. This patch series introduces core support for the Advantech
EIO-IS200 Embedded Controller (EC). The EIO-IS200 is an EC designed
for LPC (Low Pin Count) bus communication, equipped with its own PMC
(Power Management Channel) for communication with its firmware.

The EIO-IS200 EC provides a range of functionalities, including GPIO
management, watchdog timer control, hardware monitoring, I2C
communication, and thermal management. This core driver establishes
the essential infrastructure for interacting with the EIO-IS200 EC
firmware, enabling subsequent child drivers to access and utilize
these features.

This driver is essential for Linux support on hardware equipped with
the EIO-IS200 Series IC. It enables users to access and control both
firmware and hardware features, improving system stability and
functionality.

The patches have been tested on Advantech hardware platforms, and all
functionality is verified to work as expected.
