Hello, I was asked by a user of my kernel tree to try to upstream this. The patch is originally by Daniel who figured out this peculiar behaviour of the HDMI block. Since this is clearly a hack, should it even be upstreamed? Some more questions/thoughts: - I know that it works for the HDMI block on the Exynos4412, but I guess it could also work for other Exynos SoCs. So this would require some testing by someone who has access to other boards. - Currently the manipulation in hdmi_v14_mode_apply() is always active. Once we figure out for which hw the hack works, we could probably set a flag somewhere. - Same goes for mixer_atomic_check() which now always accepts 1024x768 and 1280x1024. This should also depend on a flag (maybe some CRTC flag). Feedback would be appreciated!
