[v5,00/20] drm/sched dependency handling and implicit sync fixes

Message

Hi all,

Two big changes:
- bikeshed repainted in new paint, pls don't touch, it's all fresh! The
  functions are now called _add_dependency and _add_implicit_dependencies.

- msm conversion, which includes a bugfix for the msm drm/sched
  conversion. I think it would be really good if the first two patches
  could land asap, but that means testing by some of the other drivers.
  Etnaviv especially is pending some testing/reviewed-by.

In general please review and test.

Thanks, Daniel
