You mean the device on OMAP4 has this requirement. Will this requirement exist on every platform that uses any version of this IP (or future similar IPs)?

No, it should't be in clock framework. But since the frequency range is platform-specific, it should be initialized in platform-specific code. Having min/max parameters passed by platform data as suggested by J. Keerthy is fine. Probably even better is to have the driver have a default min/max rang which can be overridden by platform_data only if needed.
