Assuming you're talking about omap SCM registers here.. This should be in a separate driver module so the control module parts can eventually be children of the SCM driver as they are really separate devices on the bus. See how the USB PHY parts were done for example. What do these control module registers do? If it's just multiplexing and pinconf, then you can use pinctrl-single,bits most likely for it and access it using the named modes. However, if the register also contains comparators and control for regulators, you should only use pinctrl-single for the multiplexing and pinconf parts.
