I should add TV power domain device exynos4_device_pd[PD_TV]  here.

You should set mixer's and hdmi's parents here to device for TV power 
domain.
You should also configure gpio for hot-plug detection. Please refer to 
function s5p_tv_setup
in arch/arm/mach-exynos4/mach-universal_c210.c:1012.

I hope you find this information useful.
