Hello David,
This series of patches fix various issues in STI drm driver. Now HDMI i2c adapter could be selected in device tree and plug detection doesn't use gpio anymore. I also had fix some signal timing problems after testing the driver on more hardware. The remaining patches attemps to simplify the code and prepare the next evolutions like DVO and auxiliary CRTC support
The changes could be fetch here: http://git.linaro.org/people/benjamin.gaignard/kernel.git on drm-sti-fixes-2014-12-04 branch
I have tested this branch on top of commit: "Merge branch 'drm-fixes-3.18' of git://people.freedesktop.org/~agd5f/linux into drm-fixes" 00d6a9b6be5885ad38234cd171f6fb18a87faa7c on drm-fixes branch.
