Hi all,

here's the fourth revision of the Host1x/TegraDRM UAPI proposal.

The changes at a high level in this revision are:
* Small bugfixes for issues reported by CI bots
* Removal of not strictly required features like sync_file FDs,
  reservations, partial mappings etc. from the submit UAPI.
* All new UAPI placed under CONFIG_DRM_TEGRA_STAGING.

The test suite[1] has been updated for the changes in this revision,

The series can be also found in
