Take CAAM's engine HWRNG: it can work both as a TRNG and as a
TRNG-seeded DRBG (that's how it's currently configured).
IIUC, both setups are fit as source for the entropy pool.

So which is it? If it's a DRBG then it should not be exposed through
the hwrng interface.  Only TRNG should go through hwrng.  DRBGs
can use the crypto rng API.
