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 https://github.com/cyndis/linux/commits/work/host1x-uapi-v4.

Thank you, Mikko
