Here are my queued changes for the Armada DRM driver, for the upcoming 4.4 merge window.
If there are no further comments (there was only one minor comment which has been fixed), I'll send a pull request for this to David later today.
These changes are about updating the driver to some of the more recent DRM APIs, and removing the non-component support now that has stabilised. This results in all of armada_output and armada_slave being removed, resulting in 460 lines of code removed from that change alone.
Other changes include:
- moving more towards supporting DRM planes in a more generic way, thereby reducing the duplication between the primary and overlay planes.
- locking cleanups, more like locking removal, prefering inherently atomic operations (eg, xchg) instead of spinlocking. This ultimately results in simpler and faster code.
I've been running these patches for a while and haven't noticed any ill effects.
Posted for comment, if nothing is forthcoming, I'll send a pull request to David in a week or so's time. These patches are against v4.2, but rebase to 4.3-rc3 without any fuss.
