v4l: vsp1: Fix suspend/resume and race on M2M pipelines
This small patchset helps rework the VSP1 driver to repair an issue on
suspend/resume operations whereby the pipeline does not get reconfigured after
it has been re-initialised following a resume operation.
Patch [1/2] is a code move only, with no functional change.
Patch [2/2] fixes the suspend/resume operations for video pipelines by marking
the new pipe configured flag as false, and configuring the pipe
during the vsp1_video_pipeline_run() call.
v5:
- Rebased for v4.12-rc1
- Dropped two patches from v4 as they are integrated already:
- BRU streamon race
- DRM scoped pipe->dl removal
v4:
- Rework and separate out the BRU race back to v1 style implementation
- Split BRU race and Suspend Resume fixes into separate commits.
v3:
- Move configured=false from vsp1_device_init to vsp1_reset_wpf()
- Clean up flag dereferencing with a local struct *
v2:
- Refactor video pipeline configuration implementation to solve both suspend
resume and the VSP BRU race in a single change
v1:
- Original pipeline configuration rework
