Subject: [PATCH v2 0/2] Set the quality value for two HW RNGs

The rng structure contains the quality field which tells how many bits
of entropy can be obtained from 1024 bits read from a device. With the
quality value set the hw_random framework starts a kernel thread to feed
the entropy pool in the CRNG, which helps to initialize it quickly
especially during boot.

  hwrng: iproc-rng200 - Set the quality value
  hwrng: exynos - Set the quality value
