OK, I got it.
The "fsl,vf610-dspi", "fsl,ls1021a-v1.0-dspi", "fsl,ls2085a-dspi" is valid and used in driver.
But "fsl,ls2080a-dspi" is just used for platform flag.
Could you help to give an example that how can I explain it in Documents?
Or should I not write this compatible in Document.
I find that many compatible strings like this (not valid just a platform flag) for other driver are not record in document.
Thanks.
