Hi all,

This series adds support for the Andes ATCSPI200 SPI controller.

Changes in v3:
- Reworked the DT binding to properly describe the compatible fallback
relationship, defining "andestech,qilai-spi" as a platform-specific
compatible that falls back to the generic "andestech,ae350-spi".
- Renamed the DT binding file from 'andestech,qilai-spi.yaml' to
'andestech,ae350-spi.yaml' to match the generic fallback compatible.
- Updated the 'compatible' property to use a 'oneOf' schema, enforcing
the fallback requirement for the specific compatible string.
- Updated the MAINTAINERS entry to reflect the renamed DT binding file.

Patch overview:
- Patch 1: Adds the device tree binding documentation.
- Patch 2: Add ATCSPI200 SPI controller driver.
- Patch 3: Add MAINTAINERS entry for the ATCSPI200 SPI controller driver.

Comments and reviews are welcome.
Thanks for your time.

Best regards,
CL
