Subject: [PATCH v4 0/9] Qualcomm video decoder/encoder driver

Hi,

Here is version 4 of the Venus video driver.

The changes since v3 are:
  * the driver now use m2m APIs. In order to make possible to
use m2m I had to extend m2m APIs with few more helper functions
for buffer list manipulations.
  * addressed comments from Hans about buffer done on error path.
  * simplify s_selection in decoder.
  * avoid simple IRQ related wrappers in core.c and use HFI ones directly.
  * added kernel doc description of venus_core|inst structures.
  * replaced list_for_each_entry_safe with list_for_each_entry where
safer variants are not applicable.
  * revisit the locking per instance and come down to one lock per
instance.
  * added help text in the driver Kconfig option.
  * deleted custom venus_ctrl structure which duplicates v4l2_ctrl_config.
  * various cleanups on random places to avoid code duplications and
to reduce the code lines.
  * removed video memory (vmem) DT properties from binding document, this
will need more work.

The previous version can be found at https://lkml.org/lkml/2016/11/7/554

regards,
Stan
