[PATCH V3 0/3] spi: atcspi200: Add support for Andes ATCSPI200 SPI controller

Posted by CL Wang 1 month, 3 weeks ago

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

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark
