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
