If this is just a pl022, then you don't need this document as
spi_pl022.txt already exists. If HiSilicon has modified this block, then
you need an additional HiSi specific compatible string and add it to
spi_pl022.txt.

This should be removed.

If this is just a pl022, then you don't need this document as
spi_pl022.txt already exists. If HiSilicon has modified this block, then
you need an additional HiSi specific compatible string and add it to
spi_pl022.txt.
