2022-09-26drm/i915: Split vlv_compute_pipe_wm() into twoVille Syrjälä
Split vlv_compute_pipe_wm() into two halves. The first half computes the new raw watermarks, and the second half munges those up into real watermarks for the particular pipe. We can reuse the second half for watermark sanitation as well.

2022-09-26drm/i915: Don't init eDP if we can't find a fixed modeVille Syrjälä
In the unlikely case of not finding a fixed mode don't register the eDP connector. I think there are some places where we'd oops if we didn't have a fixed mode for eDP so presumable this doesn't typically happen. But better safe than sorry. Also pimp the debugs with the encoder id+name. I think dumping the encoder rather than the connector provides more information here (eg. to match against the port information in the VBT). We can also drop the extra check from intel_edp_add_properties().

2022-09-23drm/i915: Move hotplug inversion logic into separate helperGustavo Sousa
Use *_hpd_invert() helpers whenever possible to isolate logic specific to hotplug inversion from common HPD setup logic to improve readability and maintainability of the source code. While we only define dg1_hpd_invert() here, future platforms are likely to have different hotplug inversion needs, thus it makes sense grouping different implementations under a common suffix. v2: Fix coding style and prefer to use small *_hdp_invert() helpers instead of a generic one.

2022-09-13drm/i915: Fix TV encoder clock computationVille Syrjälä
The TV encoder has its own special clocking strategy, which means we can't just use intel_crtc_dotclock() to figure out what the resulting dotclock will be given the actual DPLL port_clock. Additionally the DPLL can't always generate exactly the frequency we initially asked for. This results in us computing a bogus dotclock/etc., and it won't match the readout which is handled by the encoder itself properly. Naturally the state checker becomes unhappy with the mismatch. To do this sanely we'll need to move the DPLL computation into encoder->compute_config() so that all the derived state gets correctly computed based on the actual DPLL output frequency. Start doing that just for the TV encoder initally as intel_crtc_dotclock() should be able to handle other encoder types well enough. Though eventually this should be done for all encoder types rather than doing it from intel_crtc_compute_config(). With this we actually do some of the DPLL state computation twice, but we can skip the second actual .find_dpll() search by flagging .clock_set=true after we've done it once. We also still need to avoid clobbering the correct adjusted_mode.crtc_clock set up by encoder->compute_config() when called a second time from intel_crtc_compute_config().
