From: Clint Taylor <clinton.a.taylor@intel.com>
Pixel replicated modes should be 720 horizontal pixel and pixel
replicated by the HW across the HDMI cable at 2X pixel clock. Current
horizontal resolution of 1440 does not allow pixel duplication to
occur and scaling artifacts occur on the TV. HDMI certification
7-26 currently fails for all pixel replicated modes. This change fizes
the HDMI certification issues with 480i/576i.
V2: Removed interlace flag from VICs 44 and 45. Will be submitted in
another patch. Various other formatting fixes.
V3: 576i@200 htotal fixed. Check min and max pixel clocks.

Usually I reply to the previous patch version to avoid threads nesting
too badly, but other people reply to the last review comment. It
doesn't really matter.
More important is to Cc: all the people (in the commit message to make
sure it doesn't get lost, git send-email then takes care of
everything) who commented on that patch so that they'll see your
updated version.

Not at all, this just means our documentation isn't good enough yet.
Cheers, Daniel

git send-email taking care of everything is subject to
sendemail.suppresscc and other configuration values. With the git
defaults, you need to be careful not to accidentally Cc people,
typically when sending a patch privately/internally.

I tend to do the latter, but I must admit the threads sometimes get
rather messy, so I think I'll change my ways. The changelog in the
patch should anyway keep the story together.

Pixel replicated modes should be 720 horizontal pixel and pixel
replicated by the HW across the HDMI cable at 2X pixel clock. Current
horizontal resolution of 1440 does not allow pixel duplication to
occur and scaling artifacts occur on the TV. HDMI certification
7-26 currently fails for all pixel replicated modes. This change fizes
the HDMI certification issues with 480i/576i.
V2: Removed interlace flag from VICs 44 and 45. Will be submitted in
another patch. Various other formatting fixes.

Sorry, I missed the other patches comments. The CEA-861-E specification
actually has the pixel doubled values in (Table 3) the detailed sync
information data, so it does make sense to have the doubled values in
the table with /2. I prefer the actual values myself, but I am willing
to use either method.

if you prefer to have it this way I can live with it.

I don't think this comment is really useful. Just drop it IMO.

This shouldn't be needed now that the original timings are halved.

Another comment that doesn't really do anything. Can be dropped too.

* [PATCH] drm/edid: Reduce horizontal timings for pixel replicated modes

From: Clint Taylor <clinton.a.taylor@intel.com>
Pixel replicated modes should be 720 horizontal pixel and pixel
replicated by the HW across the HDMI cable at 2X pixel clock. Current
horizontal resolution of 1440 does not allow pixel duplication to
occur and scaling artifacts occur on the TV. HDMI certification
7-26 currently fails for all pixel replicated modes. This change fizes
the HDMI certification issues with 480i/576i.
