[PATCH 0/2] iommu/tegra241-cmdqv: Fix initialization and uAPI related to HYP_OWN

[Nicolin Chen]

Hi,

Eric and Shameer found a bug in kernel driver that supports_cmd is set in
an incorrect order related to the hyp_own finalization. This results in a
unnecessary command filter in the host environment that sends unsupported
(non-invalidation) commands to the SMMU CMDQ.

Also, Eric pointed it out that the requirement of VMM wiring HYP_OWN to 0
is unclear.

Thus, I am sending this small series to address these issues.
