Hi, I'm wondering if this is still being considered.
The NAK doesn't really make sense here, as there's a warning/BUG at the
bottom of the qcom SMMU driver that occurs when the compatible isn't
added:
/*
* If you hit this WARN_ON() you are missing an entry in the
* qcom_smmu_impl_of_match[] table, and GPU per-process page-
* tables will be broken.
*/
WARN(of_device_is_compatible(np, "qcom,adreno-smmu"),
"Missing qcom_smmu_impl_of_match entry for: %s",
dev_name(smmu->dev));
DTS change for context (pending):
