This patch series adds support of pseudo random number generator found in Ingenic's JZ4780 and X1000 SoC. Based on Paul's review comments, add 'syscon' compatible in CGU node in jz4780.dtsi. 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.

The rng node which is the child node of CGU is ignored so the driver's probe is not called at all. Realised that the tests were using crng instead of this. Don't know how to get this working. Will submit a new version once the issue is fixed. Please do not take this patch series. Thanks, PrasannaKumar
