This causes an issue with resume, as the functions incorrectly call vsp1_pipeline_run() directly instead of processing the video object through vsp1_video_pipeline_run(). Move the functions to the video object, renaming accordingly and update the resume handler to call vsp1_video_pipeline_run() as appropriate.

The BRS is a smaller version of the BRU with only two inputs, but otherwise offers similar features and offers the same register interface. The BRU and BRS can be used exchangeably in VSP pipelines (provided no more than two inputs are needed). Due to historical reasons, the VSP1 driver implements support for both the BRU and BRS through objects named vsp1_bru. The code uses the name BRU to refer to either the BRU or the BRS, except in a few places where noted explicitly. This creates confusion. In an effort to avoid confusion, rename the vsp1_bru object and the corresponding API to vsp1_brx, and use BRx to refer to blend unit instances regardless of their type. The names BRU and BRS are retained where reference to a particular blend unit type is needed, as well as in hardware registers to stay close to the datasheet.

It also used to contain several gaps from the time it was kept out of tree, mentioning error codes and device nodes that never existed upstream. On this series, it received a massive update: all non-deprecated digital TV APIs are now in sync with the current implementation; - Some DVB APIs that aren't used by any upstream driver got removed; - Other parts of the media documentation algo got updated, fixing some bugs on its PDF output and making it compatible with Sphinx version 1.6. As the number of hacks required to build PDF output reduced, I hope we'll have less troubles as newer versions of our documentation toolchain are released (famous last words); - As usual, lots of driver cleanups and improvements" * tag 'media/v4.14-1' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: (624 commits) media: leds: as3645a: add V4L2_FLASH_LED_CLASS dependency media: get rid of removed DMX_GET_CAPS and DMX_SET_SOURCE leftovers media: Revert "[media] v4l: async: make v4l2 coexist with devicetree nodes in a dt overlay" media: staging: atomisp: sh_css_calloc shall return a pointer to the allocated space media: Revert "[media] lirc_dev: remove superfluous get/put_device() calls" media: add qcom_camss.rst to v4l-drivers rst file media: dvb headers: make checkpatch happier media: dvb uapi: move frontend legacy API to another part of the book media: pixfmt-srggb12p.rst: better format the table for PDF output media: docs-rst: media: Don't use \small for V4L2_PIX_FMT_SRGGB10 documentation media: index.rst: don't write "Contents:" on PDF output media: pixfmt*.rst: replace a two dots by a comma media: vidioc-g-fmt.rst: adjust table format media: vivid.rst: add a blank line to correct ReST format media: v4l2 uapi book: get rid of driver programming's chapter media: format.rst: use the right markup for important notes media: docs-rst: cardlists: change their format to flat-tables media: em28xx-cardlist.rst: update to reflect last changes media: v4l2-event.rst: adjust table to fit on PDF output media: docs: don't show ToC for each part on PDF output ... 2017-08-20media: v4l: vsp1: Allow entities to participate in the partition algorithmKieran Bingham The configuration of the pipeline and entities directly affects the inputs required to each entity for the partition algorithm. Thus it makes sense to involve those entities in the decision making process. Extend the entity ops API to provide an optional .partition() operation. This allows entities that affect the partition window to adapt the window based on their configuration. Entities implementing this operation must update the window parameter in place, which will then be passed up the pipeline. This creates a process whereby each entity describes what is required to satisfy the required output to its predecessor in the pipeline.

This unfortunately resulted in incorrect timestamps in the vertical blanking events sent to userspace as vertical blanking is now handled after sending the event. To fix this we must reverse the order of the two operations. The easiest way is to handle vertical blanking in the VSP frame end handler before sending the event. The VSP frame end interrupt occurs approximately 50µs earlier than the DU frame end interrupt, but this should not cause any undue harm. As we need to handle vertical blanking even when page flip completion is delayed, the VSP driver now needs to call the frame end completion callback unconditionally, with a new argument to report whether page flip has completed. With this new scheme the DU vertical blanking interrupt isn't needed anymore, so we can stop enabling it.

Compared to a regular BRU, it supports two inputs only, and thus has no ROP unit. Add support for the BRS by modelling it as a new entity type, but reuse the vsp1_bru object underneath. Chaining the BRU and BRS entities seems to be supported by the hardware but isn't implemented yet as it isn't the primary use case for the BRS.
