HDMI is already there. >=20 > I also wonder why actually DRM_EXYNOS_HDMI has to depend on MIXER or = DECON? DECON controller has two kinds of data paths in case of Exynos5433 or l= ater. One is Display path and other is TV path. So it'd be reasonable for DRM= _EXYNOS_HDMI to depend on MIXER or DECON - TV path of DECON controller transfers Display data to HDMI like MIXER I= P of previous Exynos SoC did.
