Freescale i.MX31 SoC contains a Security Random Number Generator Accelerator module (RNGA), which is replaced by RNGB and RNGC modules on later i.MX SoC series, the change adds a new compatible property to describe the controller. Since all versions of Freescale RNG modules are legacy, apparently the documentation file has no more potential for further extensions, nevertheless generalize it by removing explicit RNGC specifics.
