[Intel-gfx] [PATCH 0/5] PSR interrupts

I have revived the PSR interrupt patches that Daniel and Ville had worked
on [1], added debugfs control for the interrupts and exposed interrupt
timestamps via debugfs. The idea is to provide a mechanism for CI tests to
know whether a PSR exit event succeeded and if PSR re-enters when it is
expected to do so. This series was tested on a SKL laptop.

Daniel Vetter (2):
  drm/i915: Enable edp psr error interrupts on hsw
  drm/i915: Enable edp psr error interrupts on bdw+

Note: This patch has Daniel's name as the author but has Ville's
Signed-off, I have left it as it is.

Dhinakaran Pandiyan (2):
  drm/i915/psr: Control PSR interrupts via debugfs
  drm/i915/psr: Timestamps for PSR entry and exit interrupts.

Ville Syrjälä (1):
  drm/i915: Drop reg_write from the PSR mask
