Subject: [PATCH v2 0/2] hwrng: add support for Silex Insight BA431

Hello all,

This set of patches aims at introducing a linux hwrng driver for the
Silex Insight BA431 IP which is available for various FPGA.
This hardware is for instance present in Silex Insight Viper OEM boards.

The first patch documents the device tree bindings.
The second one contains the BA431 hwrng driver.

Changes in v2:
  - Dropped the first patch that has been applied by Rob.
  - Added Rob's review tag in the first patch.
  - Fixed copyright header.
  - Added missing endpoint and "If unsure, say Y" in the Kconfig like it is
    done for the other rng drivers.
  - Replaced the udelay() loop by readx_poll_timeout() in the driver.
  - Added Arnd's ack in the second patch.
