This series adds support for handling "v2" firmware's IOMMU, found
on at least MSM8956 and MSM8976 (some other SoCs also need the same
but I honestly don't remember which ones precisely).
This is strictly required to get functional IOMMUs on these SoCs.
I'm sorry for not performing a much needed schema conversion on
qcom,iommu.txt, but I really didn't have time to do that :-(
This series was tested on Sony Xperia X and X Compact (MSM8956):
ADSP, LPASS, Venus, MSS, MDP and GPU are happy :-)
Hello,
this series is really old and got sent and resent many times.
The first time I've sent this one was .. I think in 2019, then, at the
end of 2022, I had some time to actually respin it and send another
three versions. It's been 3 long years :-)
The third version got the last comments addressed.
Since this didn't get any more feedback for 3 months, I'm worried that it
will be forgotten again, hence:
Is there any more feedback? Anything else to fix?
If not, can this be picked, please?
Thank you.
Best regards,
Angelo
Changes in v3:
- Removed useless FSRRESTORE reset and definition as pointed
out in Robin Murphy's review
- Fixed qcom,iommu.txt changes: squashed MSM8976 compatible
string addition with msm-iommu-v2 generics addition
Changes in v2:
- Added back Marijn's notes (sorry man!)
- Added ARM_SMMU_CB_FSRRESTORE definition
- Changed context bank reset to properly set FSR and FSRRESTORE
