Subject: [PATCH v2 0/3] hwrng: imx-rngc - simplify register definitions

This series simplifies some definitions for register bits and fields. We can
then use the FIELD_GET macro to read register fields instead of masking and
shifting manually.

Tested on an imx258 board (rngb).

v2:
 - simpler check if random bytes are available

Martin Kaiser (3):
  hwrng: imx-rngc - simpler check for available random bytes
  hwrng: imx-rngc - use bitfield macros to read rng type
  hwrng: imx-rngc - use BIT(x) for register bit defines
