Whilst the driver continues to support these for old dt blobs, any dt bindings that are actuallly verified against this document should be fixed to add the vendor name. Enforces rule that spi-cpol == spi-cpha. Is there a cleaner way to do this? Added the #io-channel-cells property to allow for consumers.
