Exynos5433 support is being incrementally merged (clocks, drm, phy, pinctrl, thermal and tty support is already in upstream or -next). I don't know why DTS changes got stuck in Kukjin's tree (Kukjin, could you please explain?) but I think that this shouldn't not stop us from continuing Exynos5433 upstreaming effort.
