The MCAN module doesn't have sysconfig registers.If there's no sysconfig register you should have no need for adding anything to omap_hwmod_7xx_data.c. We now have the dts clkctrl clocks, you can just add that to the dts node for the device.
However.. My guess is there is somewhere a top level interconnect target module that uses DRA7XX_CM_WKUPAON_ADC_CLKCTRL. And that module may have multiple child devices. Regards, Tony
