yes, this interrupt is only needed for DMA transfers.

there should be only one compatible string in the DTS. For backward
compatibility the driver could support old and new strings.

AFAIK the upstream preference is to have "lantiq,<soc>-spi". I forgot
to fix that in the driver. Could you change that? Thanks.
