This patch adds this property to hdmi device node which is bound by HDMI driver of Exynos DRM. As we talked about this at other email thread, seems this property is required mandatorily for Odroid XU3/4 board which uses Exynos5422.
There may be something I'm missing so could you let me know how this property is required?

Thanks,
Inki Dae
