> This series fixes and greatly simplifies the Xilinx TRNG driver by:
>
> - Removing the gratuitous crypto_rng interface, leaving just hwrng which
>   is the one that actually matters.
>
> - Replacing the really complicated AES based entropy extraction
>   algorithm with a much simpler one.
>
> Note that this mirrors similar changes in other drivers.

>   crypto: xilinx-trng - Replace crypto_drbg_ctr_df() with HMAC-SHA512
>   hwrng: xilinx - Move xilinx-rng into drivers/char/hw_random/
