[PATCH 0/3] Subject: [PATCH 0/3] gpio: add support for Axiado SGPIO controller

[Petar Stepanovic]

The SGPIO controller provides a serialized interface for
controlling multiple GPIO signals over a limited number of
physical lines. It supports configurable data direction and
interrupt handling.

This series adds support for the Axiado SGPIO controller.

The series includes:
- Device tree binding documentation
- GPIO driver implementation
- MAINTAINERS entry

The driver integrates with the Linux GPIO subsystem and
registers the controller as a gpio_chip.

Tested on Axiado platforms.
