On linux-samsung tree the only patch that's missing apart from dptx-phy patches is the syscon patch from Pankaj Dubey: b784b98 mfd: syscon: Decouple syscon interface from platform devices
So with below git hash, linux-samsung/for-next display works fine along with other devices that request PMU system controller :

are you using a clean exynos_defconfig? don't you need Javier's "drm/exynos: Move platform drivers registration to module init" patch too?

hangs with a black screen (albeit backlight seems to be on) on boot. I'm betting on Javier's patch at this point (i even tried disabling SND_SOC_SNOW but that didn't help).
