Gareth Yu	1c57014325	drm/i915/dsi: Enforce pipeline flush with DSI HS transfer ... With all of the boundary conditions when streaming the commands B2B in our validation (part of the reason we added the flush), the Flush effectively serializes the transmission of each command enqueued within the command dispatcher to one per V. Blank line which simplifies the behavior of the High Speed Arbitration. So, unless we absolutely have to burst these to the Sink, we should be using the Pipeline Flush bit to serialize the commands.

Jani Nikula	e563531ace	drm/i915: split out intel_display_reg_defs.h ... Split out the display register helper macros to a separate file. For now, include it from i915_reg.h, but note that there are already files that don't need i915_reg.h, such as intel_audio.c.

Jani Nikula	3c0deb1485	drm/i915/reg: split out icl_dsi_regs.h ... The ICL DSI registers have fairly isolated usage. Split the register macros to a separate file.
