[Intel-gfx] [PATCH 0/7] Even more "unclaimed register" fixes

[Paulo Zanoni]

From: Paulo Zanoni <paulo.r.zanoni at intel.com>

Hi

This is yet another series of patches that prevent our driver from touching
registers that don't exist or are powered off. With this series applied we
shouldn't trigger any "unclaimed register" message when there's a GPU hang or
when i915.disable_power_well=1 and the audio drivers are blacklisted. I'm not
aware of any other "unclaimed register" errors caused by the i915.ko driver.

The first 2 patches on the series are brand new, fixing recent regressions. The
third patch was requested by Daniel Vetter on an email this week. Patches 4-7
are new versions of patches I sent in the last round.

Thanks,
Paulo

  drm/i915: add intel_display_power_enabled
  drm/i915: add power well and cpu transcoder info to the error state
  drm/i915: clear FPGA_DBG_RM_NOCLAIM when capturing error state
  drm/i915: check the power well on i915_pipe_enabled
  drm/i915: only disable DDI sound if intel_crtc->eld_vld
