2023-11-17drm/i915: move *_crtc_clock_get() to intel_dpll.cJani Nikula
Considering what the functions do, intel_dpll.c is a more suitable location, and lets us make some functions static while at it. This also means intel_display.c no longer does any DPIO access.

2022-04-25drm/i915: Add crtc .crtc_get_shared_dpll()Ville Syrjälä
Start splitting the .compute_crtc_clock() into two parts; one part does the computation, the second part does the shared dpll assignment. I want to move the actual computation part much earlier into the compute_config() phase. v2: dg2_crtc_get_shared_dpll() not needed (Jani) Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20220325123205.22140-10-ville.syrjala@linux.intel.com Reviewed-by: Jani Nikula <jani.nikula@intel.com>
2022-04-25drm/i915: Adjust .crtc_compute_clock() calling conventionVille Syrjälä
Pass the full atomic state+crtc rather than the redundant crtc+crtc_state pair. We already need the full atomic state in the hsw+ codepath anyway.

Avoid referencing the function pointer directly to be able to abstract the call better.

2021-08-25drm/i915: Call {vlv,chv}_prepare_pll() from {vlv,chv}_enable_pll()Ville Syrjälä
We always call the vlv/chv prepare_pll() just before enable_pll(). Move the calls into the enable_pll() funcs. We can also consolidate the DPLL_VCO_ENABLE checks while at it.

2021-01-16drm/i915: refactor pll code out into intel_dpll.cDave Airlie
This pulls a large chunk of the pll calculation code out of intel_display.c to a new file. One function makes sense to be an inline, otherwise this is pretty much a straight copy cover. Also all the remaining hooks for g45 and older end up the same now.
