1 entry was valid and now it is not? That's not a compatible change and needs an explanation at a minimum.

Yes, as the driver returns error in the absence of SAPB port address range, this may break the driver on platform without SAPB port. This IP needs SAPB port to support HDCP feature using embedded HDCP crypto module.

So, to maintain backward compatibility I will modify the driver and allow it to proceed without HDCP feature, instead of returning an error, in case of no SAPB port.
