Zephyr commit 774370a1d712 ("boards: nxp: imx95_evk_mimx9596_m7: add uart
dma support") replaces the configuration of the "edma2" node with that
mandated by the programming model associated with the "nxp,mcux-edma"
compatible. This change was done because the EDMA driver associated with
said compatible is compatible with multiple peripheral drivers as opposed
to the previous "nxp,edma" driver.
However, SOF currently requires using the previous EDMA driver (i.e. the
one associated with the "nxp,edma" driver). Therefore, switch back to the
previous programming model.
Furthermore, the DMA channels used by the SAI IP were also changed. Since
these were not tested, switch back to the previous DMA channels.

Thanks! @LaurentiuM1234. I forgot to update the DMA channels used by SAI on imx-stable-v2.14. I will backport your patch once merged. |

There was a problem hiding this comment.
@LaurentiuM1234 can this be merged first, and then the Zephyr west update?

should be fine. I was expecting the build tool to complain when applying the overlay but I guess not? |

@lrudyX @lgirdwood ignored the Intel quickbuild fail, this PR (NXP overlay change only) cannot possibly influence Intel builds. |
