Douglas Anderson 9a5f0b11e4 arm64: dts: qcom: sc7180: Mark SCM as dma-coherent for IDP ... sc7180-idp is, for most intents and purposes, a trogdor device. Specifically, sc7180-idp is designed to run the same style of firmware as trogdor devices. This can be seen from the fact that IDP has the same "Reserved memory changes" in its device tree that trogdor has. Recently it was realized that we need to mark SCM as dma-coherent to match what trogdor's style of firmware (based on TF-A) does [1]. That means we need this dma-coherent tag on IDP as well. Without this, on newer versions of Linux, specifically those with commit 7bd6680b47 ("Revert "Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()"""), WiFi will fail to work. At bootup you'll see: qcom_scm firmware:scm: Assign memory protection call failed -22 qcom_rmtfs_mem 94600000.memory: assign memory failed qcom_rmtfs_mem: probe of 94600000.memory failed with error -22 [1] https://lore.kernel.org/r/20230615145253.1.Ic62daa649b47b656b313551d646c4de9a7da4bd4@changeid Fixes: 7bd6680b47 ("Revert "Revert "arm64: dma: Drop cache invalidation from arch_dma_prep_coherent()""") Fixes: f5ab220d16 ("arm64: dts: qcom: sc7180: Add remoteproc enablers") Signed-off-by: Douglas Anderson <dianders@chromium.org> Link: https://lore.kernel.org/r/20230616081440.v2.2.I3c17d546d553378aa8a0c68c3fe04bccea7cba17@changeid Signed-off-by: Bjorn Andersson <andersson@kernel.org>		2023-06-22 12:20:12 -07:00
