Here the dispc_features not only mention the omap name but also the
revision like omap3_3_0_dispc_features which initializes data for
OMAP3430_REV_ES3_0 and higher. May be omap34xx_rev3_0_dispc_features
is a better name for this. For others omap44xx_dispc_features kind of
name should be ok without revision number being mentioned. What d you
say?
