This patchset contains the hw random number generator support for the Broadcom's NSP SoC. The block is similar to the block available in bcm2835 with different default interrupt mask value. Due to lack of documentation, I cannot confirm the interrupt mask register details in bcm2835. In an effort to not break the existing functionality of bcm2835, I used a different compatible string to mask the interrupt for NSP SoC. Please let me know. Also supported providing requested number of random numbers instead of static size of four bytes. The first patch contains the documentation changes and the second patch contains the support for rng available in NSP SoC. The third patch contains the device tree changes for NSP SoC. The fourth patch contains the support for reading requested number of random numbers. This patch set has been tested on NSP bcm958625HR board.
