Don't do that as it breaks bisectability. If you are changing an interface like this it has to occur in one patch, of you have to have intermediate code that deals with the smooth transition. Otherwise, looks like a sensible bit of rework to me.

I thought about it, but wasn't sure. Will create a v3 with patches 3 & 4 squashed.

The ADIS library is one of the few users of the new `cs_change_delay` parameter for an spi_transfer. The introduction of the `spi_delay` struct, requires that the users of of `cs_change_delay` get an update. This change updates the ADIS library.
