This patch adds the display mode check operation to exynos_mixer_ops in drm-common-hdmi. In Exynos SoCs, mixer IP can put certain restrictions on the proposed display modes. These restriction needs to be considered during mode negotiation, which happens immediately after edid parsing. Both, mixer check-mode and hdmi check-timing callbacks are called one after another and ANDed result is returned back.
