Series arm64: dts: qcom: sm6125: Enable APPS SMMU |

Commit Message

Marijn Suijten Dec. 22, 2022, 7:32 p.m. UTC 
  When enabling the APPS SMMU the mainline driver reconfigures the SMMU
from its bootloader configuration, losing the stream mapping for (among
which) the SDHCI hardware and breaking its ADMA feature.  This feature
can be disabled with:

    sdhci.debug_quirks=0x40

But it is of course desired to have this feature enabled and working
through the SMMU.
