[PATCH 1/4] drm/edid: Make drm_get_cea_aspect_ratio() static

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

drm_get_cea_aspect_ratio() is not used outside drm_edid.c.
Make it static.

[PATCH 2/4] drm/edid: Extract drm_mode_cea_vic()

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Extract the logic to compute the final CEA VIC to a small helper.
We'll reorder it a bit to make future modifications more
straightforward. No function changes.

[PATCH 3/4] drm/edid: Fix HDMI VIC handling

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

Extract drm_mode_hdmi_vic() to correctly calculate the final HDMI
VIC for us. Currently this is being done a bit differently between
the AVI and HDMI infoframes. Let's get both to agree on this.

We need to allow the case where a mode is both 3D and has a HDMI
VIC. Currently we'll just refuse to generate the HDMI infoframe when
we really should be setting HDMI VIC to 0 and instead enabling 3D
stereo signalling.

If the sink doesn't even support the HDMI infoframe we should
not be picking the HDMI VIC in favor of the CEA VIC, because then
we'll end up not sending either VIC in the end.

[PATCH 4/4] drm/edid: Prep for HDMI VIC aspect ratio (WIP)

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

I think this should provide most of necessary logic for
adding aspecr ratios to the HDMI 4k modes.

There are no picture_aspect_ratio attributes defined for modes in 
edid_4k_modes[] now. Should add on those definitions.

Current code in drm_match_hdmi_mdoe() & drm_match_hdmi_mode_clock_tolerance()
use hdmi_mode_alternate_clock() to find alternate clocks.
In hdmi_mode_alternate_clock(), it adds an exception for VIC 4 mode (4096x2160@24)
due to there is no alternate clock defined for that mode in HDMI1.4b. But HDMI2.0 adds
23.98Hz for that mode. Maybe we should also revise that part.

I'm tempted to just remove that exception. I have a hard time imagining
it causing serious problems.

Thanks for your time.
I've run smoke test and CTS to verify these patches (with adding the aspect ratio 
attribute to edid_4k_modes[] and removing the exception for23.98Hz). So far it
looks good on my environment. Is there any further modification should be done
on these patches?
