++Secure SoCs may provide RNG via secure ROM calls like Nokia N900 does. The
++implementation can depend on the SoC secure ROM used.

++ Definition: must be "nokia,n900-rom-rng"

++ Definition: reference to the the RNG interface clock

++ *
++ * - Minimum STROBE_READ i.e. the time to wait post OTP fuse burn before
++ * performing another read is 37 nanoseconds
++ *
++ * - Minimum RELAX timing is 17 nanoseconds. This final RELAX minimum
++ * timing is not entirely clear the documentation says "This
++ * count value specifies the time to add to all default timing
++ * parameters other than the Tpgm and Trd. It is given in number
