[PATCH v4 0/4] SDM670 GPI DMA support

[PATCH v4 0/4] SDM670 GPI DMA support

[Richard Acayan]

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.

  dt-bindings: dma: qcom: gpi: add compatible for sdm670

[PATCH v4 1/4] dt-bindings: dma: qcom: gpi: add fallback compatible

[Richard Acayan]

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.

[PATCH v4 4/4] dmaengine: qcom: deprecate redundant of_device_id entries

[Richard Acayan]

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.
