Re: [PATCH v2 2/6] media: verisilicon: Don't hold the VPU in reset after remove

Yes. The IOMMU is inside the AV1 block and the TRM has no reset for it,
only these four. v3 adds them to the vsi-iommu binding and node.

v3 does that: both drivers get them as released exclusive controls.
vsi-iommu acquires them to deassert on probe, hantro for its probe
deassert and for the timeout pulse of the encoder cores. Remove still
leaves them deasserted.

v3: https://lore.kernel.org/r/20261113-hantro-robust-v3-0-82383c722ad2@xxxxxxxxx
