Sorry for the delay, the idea is good now that we don't need the
revision check super early any longer. Few comments below.

Can you please split this patch a bit? First a patch that does not
change the behaviour except adds the SoC specific revision checks.

Maybe just call ti816x_check_features separately?

	omap3xxx_check_revision();
	omap3xxx_check_features();
and
	omap3xxx_check_revision();
	ti816x_check_features();
