1st patch for generic reset in this series is independent and can be
merged.
But seems like requesting direct mapping fails with the joerg's patch
series.
Thanks,

What is the status of this series, is it ready to land or are any changes
needed?

This series allows drm devices to set a default identity
mapping using iommu_request_dm_for_dev(). First patch is
a cleanup to support other SoCs to call into QCOM specific
implementation and preparation for second patch.
Second patch sets the default identity domain for drm devices.
