* drm/i915: s/PIPECONF/TRANSCONF/Ville Syrjälä2023-02-171-8/+8
| | | | | | | | | | | | | | | | | | | Rename PIPECONF to TRANSCONF to make it clear what it actually applies to. While the usual convention is to pick the earliers name I think in this case it's more clear to use the later name. Especially as even the register offset is in the wrong range (0x70000 vs. 0x60000) and thus makes it look like this is per-pipe. There is one place in gvt that's doing something with TRANSCONF while iterating with for_each_pipe(). So that might not be doing the right thing for TRANSCODER_EDP, dunno. Not knowing what it does I left it as is to avoid breakage.

* drm/i915: Give CPU transcoder timing registers TRANS_ prefixVille Syrjälä2023-02-171-7/+7
| | | | | | | | | | | | | | | | | | | | | | Name the CPU transcoder timing registers TRANS_FOO rather than just FOO. This is the modern name, after the pipe/transcoder split happened. Makes it a bit more obvious whether you pass in a pipe or a transcoder. PIPESRC is a bit special as it's a pipe register, even though it lives in the transcoder registers range (0x60000 instead of 0x70000). And BCLRPAT I suppose is a transcoder register (since it has something to do with the timing generator), but it doesn't even exist after gen4 so I left it to use the only name it ever had in bspec. And while at it let's pass in the correct enum in few more places why don't we. Although in all those places the distinction doesn't matter.

* drm/i915: stop including i915_irq.h from i915_trace.hJani Nikula2022-11-111-0/+1
| | | | | | | | | | | | | | | | | | | Turns out many of the files that need i915_reg.h get it implicitly via {display/intel_de.h, gt/intel_context.h} -> i915_trace.h -> i915_irq.h -> i915_reg.h. Since i915_trace.h doesn't actually need i915_irq.h, makes sense to drop it, but that requires adding quite a few new includes all over the place. Prefer including i915_reg.h where needed instead of adding another implicit include, because eventually we'll want to split up i915_reg.h and only include the specific registers at each place. Also some places actually needed i915_irq.h too.
