What happens moderately often (not just for OMAP) is that the driver
level change is a stable suitable change by itself but starting to use
the driver can expose a requirement to do additional work on some
existing SoCs to integrate it properly since the driver starts using SoC
integraton that isn't altogether there or correct.
