OK so we already have set_globals_control, but we're not using it..
No need for this line is added above.
Let's do the attached clean-up patch and just leave omap_control_base
out of the driver for now as it's not currently needed there.
If omap_control_base is needed in the driver, then we need to pass
it in the platform_data to the driver for the non-DT boot case, or
parse it from DT like you're doing.

Tony

Subject: [PATCH] ARM: OMAP2+: Change omap_type() to use omap_ctrl_base_get()
We have the SoC specific ctrl_base already initialized in
set_globals.
