Hi Mark, I've tried your suggestion of doing things at the marshalling level and would be interested to hear what you think of the result. Note these patches are not clean yet hence no sign offs. The tricky bit was triggering the two separate writes per register and the result is somewhat hacky. An alternative there would be to add some configuration options to the spi_write (or allow a couple of varients) so as to break the long transfer that would generate up and hence bounce the cs line in the right place. Gah. SPI can be so uggly sometimes. If this approach isn't acceptable in principle I'll give up and conclude that these parts will never play well! (which is fine by me if true).
