[PATCH v3 0/4] crypto: Add driver for JZ4780 PRNG

[PrasannaKumar Muralidharan <prasannatsmkumar@gmail.com>]

This patch series adds support of pseudo random number generator found
in Ingenic's JZ4780 and X1000 SoC.

Create cgublock node which has CGU and RNG node as its children. The
cgublock node uses "simple-bus" compatible which helps in exposing CGU
and RNG nodes without changing CGU driver. Add 'syscon' compatible in
CGU node in jz4780.dtsi. The jz4780-rng driver uses regmap exposed via
syscon interface to access the RNG registers. CGU driver is not
modified in this patch set as registers used by CGU driver and this
driver are different.
