[PATCH 0/3] Assorted changes for Exynos PRNG driver

Hello,

This is a series of patches for exynos-rng driver I've decided to
create after adding support for Exynos5250+ chips. They do not
strictly depend on each other, but I think it is better to send them
as a single patch-set.

Patch #1 Add support for PRNG in Exynos5250+ SoCs

Patch #2 Improve output performance by using memcpy() rather than a
custom function to retriev random bytes from registers.

Patch #3 Reseed the PRNG after reading 2^16 bytes. Simmilar approach
is implemented in DRBG. (Thanks Stephan Mueller)
