Subject: [PATCH v5 0/3] hw_random: introduce Arm CryptoCell TRNG driver

The Arm CryptoCell is a hardware security engine.
This patch introduces driver for its TRNG (True Random Number Generator)
engine.

v5 changes:
	1. in arm-cctrng.yaml, fixed error in 'make dt_binding_check'
	2. in cctrng.c, clean up cctrng clock handling

v4 changes: update arm-cctrng.yaml to conform with json-schema standard.

v3 change: removed few unneeded "#ifdef CONFIG_PM" from the code.

v2 changes: fixed 'make dt_bnding_check' errors.

Hadar Gat (3):
  dt-bindings: add device tree binding for Arm CryptoCell trng engine
  hw_random: cctrng: introduce Arm CryptoCell driver
  MAINTAINERS: add HG as cctrng maintainer
