Subject: [PATCH 0/9] media: hantro: Add support for H264 decoding

Hello,

This patch series adds support H264 decoding support to the hantro
driver and doing some consilidation cleanup in the driver along the
way.

Some details about the patches forming this patchset:

* The first patch is adding support for the sort_r() variant and has
  been posted separately by Rasmus. I put it back there because Andrew
  told me to repost it with the patch series using this new variant.
  As mentioned in the patch itself, I'd like this patch to be merged
  as soon as possible to avoid the synchronisation burden that might
  appear if we decide to delay it.

* Patch 2 is needed to properly propagate the output buf timestamp to
  the capture buf one, which is required for intra-frame references.

* Patches 3 to 6 are consolidating the code by providing helpers that
  can be used by all hantro backend and simplifying the ctrl
  initialization logic. We also constify the controls array.

* Patches 7 to 8 are adding common H264 decoding bits and patch 9 is
  enabling H264 decoding on rk3288

Now, a few words about the dependencies. Unfortunately there are a lot,
and that'd be great to have some of them merged.

* This series is based on top of Ezequiel's VP8 work [1].
* It depends on [2] which defines/described the H264 decoding mode
  control.
* Depends on [3] since I'm using vb2_get_buffer() to retrieve a
  reference buffer
* The final dep is a fix I sent this morning allowing me to simplify the
  ctrl initialization logic

Regards,

Boris
