Taking just those screws up the rest of the series, as I previously explained: > On Thu, Aug 27, 2015 at 10:39:12AM +0200, Philipp Zabel wrote: > > Unfortunately these timings are completely different from what Freescale > > came up with for the TV Encoder on i.MX5, but the code we have currently > > in mainline doesn't work for that either.

Philipp sent a tested-by, but that was about the only attributation I received from posting the set, so I only sent David what I was fully happy to send at the time. I'm willing to send: drm: bridge/dw_hdmi: improve HDMI enable/disable handling drm: bridge/dw_hdmi: add connector mode forcing drm: bridge/dw_hdmi: add support for interlaced video modes gpu: imx: fix support for interlaced modes gpu: imx: simplify sync polarity setting now, which are patches 3, 4, 5, 11 and 12 from the original 12 patch series. The actual audio patches I think need to be held _even_ longer, because it's unclear what's happening with ALSA in regard to HDMI audio. There's also the need to sort out what's going on with CEC (thanks to the late arrival of the CEC project by Hans) which may influence how the HDMI audio part gets to hear about the display's capabilities. So, yet again I can see audio missing the next merge window, which is just how it's been for the last two years. Actually, right now I think we ought to say: sod it, these patches have been around for long enough that they should just be merged, and then we'll sort out whatever changes are necessary later when the CEC and audio situation finally gets sorted... but are you happy with having what is essentially an ALSA driver in drivers/gpu/drm/bridge? If not, why haven't you responded to the many times that the patches have been posted? At this stage, I'm getting to be very rebelious, and it's very tempting for me to say "sod you" or just drop the work entirely if you have any objections. I feel I've put fsck loads of work into this area for very little mainline progress, and I'm just not going to continue doing that. -- FTTC broadband for 0.8mile line: currently at 9.6Mbps down 400kbps up according to speedtest.net. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
