Add support for the built-in cryptographic accelerator. This accelerator

It also supports full IPSEC, SRTP and TLS offload.

I guess you can drop the extra new line between clocks interrupts and resets.

It makes sense.


Does the driver supports these property tho? For example the clock is just
enabled or tweaked to a specific frequency? Same question for resets.

As far as I know, the driver doesn't use these properties. They may be used
in the future.
