[PATCH 0/7] drm: add atomic state logging and debugfs

[Rob Clark]

I realized that I had not re-sent this after updating from review
comments, and adding kerneldoc.

The drm/msm bits I can include in my msm-next pull-req for 4.10.  Just
including them here to show example usage.

There will be a minor conflict to resolve around drm_get_format_name(),
depending on what the final solution there is.  But that should be
trivial.  If needed I can rebase after that lands.  But would be nice
if this ended up in drm-next for 4.10 so that I can land the drm/msm
bits (and some later patches that use drm_printer to dump SMP state
in debugfs and on error irqs)

Rob Clark (7):
  drm: helper macros to print composite types
  drm: add helper for printing to log or seq_file
  drm: add helpers to go from plane state to drm_rect
  drm/atomic: add new drm_debug bit to dump atomic state
  drm/atomic: add debugfs file to dump out atomic state
  drm/msm/mdp5: add atomic_print_state support
  drm/msm: module param to dump state on error irq
