Hi, As it usually happens when there is a fair amount of HW IP block re-use, competing implementations show up. In that case the BCM2835 HWRNG driver and the BCM63xx RNG driver have exactly the same register offsets and this is indeed the same piece of HW. This patch series first prepares the bcm2835-rng to be more future proof and support newer platforms, and the last part brings in what is necessary to migrate the bcm63xx-rng over to bcm2835-rng. Finally we delete bcm63xx-rng completely. The reason why BCM2835 RNG was kept over BCM63xx RNG is because the former deals correctly with a warm up count and the number of words available in the FIFO size. Thanks!
