Subject: Re: [PATCH v2 19/19] dt-bindings: spi: Convert DW SPI binding to DT
 schema

Rob,
Could you take a look at this patch? We are getting closer to merging the series
into the spi/for-next branch and then to the kernel 5.8. It would be great to
have the bindings converted by the next merge window.
