Added a property to enable user space to set aspect ratio.
This patch contains declaration of the property and code to create the
property.

This seems like it should be either an HDMI specific property, since it
uses values defined by HDMI/CEA. Alternatively we could introduce some
new generic enumeration and translate that to the HDMI/CEA equivalent in
the AVI infoframe helpers.

Doing so would allow us to add aspect ratios different from what HDMI or
CEA define.

I don't think you need the temporary aspect_ratio variable here. Can't
you directly assign the new property to .aspect_ratio_property?

Documentation update is missing. Also for such patch series I recommend to
post the entire patch series to dri-devel and intel-gfx. Otherwise people
on dri-devel don't see how the new code is used and so can't really review
it properly.

Thanks for your inputs.
I will make the following changes and resend the patch..
- Make the enum generic and translate that to the HDMI/CEA equivalent
for AVI IF.
- Remove the temporary aspect_ratio variable.

Thanks,

I will send the Documentation change along with the rest of the patches
(when I resend them).
Resent patch 3 adding dri-devel..

Hi Daniel,
For the Documentation update, should HTML table format be used in
drm.tmpl or is there some other method?
