Good point, I'll definitely give that a go once the current issues are resolved.

Which are: These changes make 5250-based machines (snow and arndale)
break. Lots of i2c timeouts on SATA and hdmi-phy. Looks like arndale
might be missing pinctrl setups for it?

Tushar, Kukjin, any chance you can investigate from your end? I'd like
to get this change in since it allows for better multiplatform
coverage, but the Exynos breakage must be fixed...
