Populate PAR in infoframe structure. If there is a user setting for PAR, then
that value is set. Else, value is taken from CEA mode list if VIC is found.
Else, PAR is calculated from resolution. If none of these conditions are
satisfied, PAR is NONE as per initialization.
As a next step, create a property that would enable a user space app to set
aspect ratio. (will be pushed as a separate patch)

Please pardon my ignorance, but how can userspace actually set this part
of the mode? I couldn't find any code which sets this anywhere ...

Ah, that makes more sense. I think we should move the property also into
the drm core so that all drivers that want to expose this can use the same
property. Also if you have patches which depend upon each another in a
funtional way it's better to post them together in one series.

Ok, I will modify the patch (which adds aspect ratio property) to move
the property to drm and resend separately.
This patch as it is unblocks AVI infoframe compliance test, so can this
patch be considered for acceptance now?

Without the 2 lines to look at mode->picture_aspect_ratio I think yes.

Populate PAR in infoframe structure. If there is a user setting for PAR, then
that value is set. Else, value is taken from CEA mode list if VIC is found.
Else, PAR is calculated from resolution. If none of these conditions are
satisfied, PAR is NONE as per initialization.
v2: Removed the part which sets PAR according to user input, based on
Daniel's review comments.
A separate patch will be submitted to create a property that would enable a
user space app to set aspect ratio for AVI infoframe.

I'm not sure if providing the PAR for non-CEA modes like this makes
any real difference. But I guess it can't hurt since you only provide
it for exact matches.
But the matches are maybe even a bit too exact. For instance 1366x768
will not match the 16:9 case. So maybe it should be calculated in a bit
more relaxed way.
Or just dropped totally. I'm not sure.

Maybe we can drop it for now (for this patch) and come up with another
patch containing calculations which are more relaxed than the above.
What do you think?

Populate PAR in infoframe structure. If there is a user setting for PAR, then
that value is set. Else, value is taken from CEA mode list if VIC is found.
Else, PAR is calculated from resolution. If none of these conditions are
satisfied, PAR is NONE as per initialization.
v2: Removed the part which sets PAR according to user input, based on
Daniel's review comments.
v3: Removed calculation of PAR for non-CEA modes as per discussion with
Ville.
A separate patch will be submitted to create a property that would enable a
user space app to set aspect ratio for AVI infoframe.

v2: Removed the part which sets PAR according to user input, based on
Daniel's review comments.
v3: Removed calculation of PAR for non-CEA modes as per discussion with
Ville.
v4: Added description for the param video_code. Absence of the description
led to a warning while executing "make htmldocs", as reported by
Wu, Fengguang.
Modified commit message.
A separate patch will be submitted to create a property that would enable a
user space app to set aspect ratio for AVI infoframe.

I've pulled this into my topic/core-stuff branch so it doesn't get lost.

Applied. btw if I've merged a patch already I prefer a small fixup patch
on top of what I have to squash into the main patch.
