Hi all,
This patch series adds support for the Broadcom BCM5301x SoCs random number
generator which is the same block as the one found in NSP and BCM2835.
Florian Fainelli (3):
Documentation
This series of patchsets contains the Broadcom Random Number Generator
driver and device tree binding documentation.
Changes from v2:
added usleep_range instead of cpu_relax
add init and cleanup functions following new hwrng model
Changes from v1:
added \n to 2 dev_err messages

This adds a driver for random number generator present on Broadcom
IPROC devices.
