The main differences with the previous generation of SoC is that some blocks have two clock sources instead of one and that the clock source can be the one of the clock output of another OLB instead of the main oscillator. For the blocks with a single parent clock, the name if that clock is "ref", similar to what is done for the OLB of the previous SoC. The blocks with two parent clocks use the names of the reference clocks generated by the other OLB or the main oscillator. Some OLB also contain a reset controller with one or more reset domain, like the blocks found in the eyeQ6H.
