Changes since v5:
- add back dts patch (4/4)
- remove blank line (1/4)
- add review tag from v4 (4/4)
Changes since v4:
- drop dts patch (to be sent separately)
- accumulate review tags
Changes since v3:
- keep other compatible strings in driver and add comment
- accumulate review tags
Changes since v2:
- change fallback to sdm845 compat string (and keep compat string in
driver)
- fallback now only affects two SoCs + SDM670
Changes since v1:
- add fallback compatible
This patch series adds the compatible string for GPI DMA, needed for the
GENI interface, on Snapdragon 670.

The drivers are transitioning from matching against lists of specific
compatible strings to matching against smaller lists of more generic
compatible strings. Use the SDM845 compatible string as a fallback in
the schema to support this change.

The Snapdragon 670 uses GPI DMA for its GENI interface. Add a compatible
string for it in the documentation.

The drivers are transitioning from matching against lists of specific
compatible strings to matching against smaller lists of more generic
compatible strings. Add a message that the compatible strings with an
ee_offset of 0 are deprecated except for the SDM845 compatible string.

The dt schema for gpi-dma has been updated with a new fallback
compatible string. Add the compatible strings to existing device trees.
