This patch series adds support of pseudo random number generator found in Ingenic's JZ4780 and X1000 SoC. The PRNG hardware block registers are a part of same hardware block that has clock and power registers which is handled by CGU driver. Ingenic M200 SoC contains power related registers that are present after the PRNG registers. So instead of reducing the register range, syscon interface is used to expose a register map that is used by both CGU driver and this driver. Changes made to jz4740-cgu.c is only compile tested.
