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.
