Subject: [PATCH 07/10] dt-bindings: rng: add st,rng-lock-conf
Date: Fri, 8 Sep 2023 18:51:17 +0200 [thread overview]
Message-ID: <20230908165120.730867-8-gatien.chevallier@foss.st.com> (raw)
In-Reply-To: <20230908165120.730867-1-gatien.chevallier@foss.st.com>
If st,rng-lock-conf is set, the RNG configuration in RNG_CR, RNG_HTCR
and RNG_NSCR will be locked. It is supported starting from the RNG
version present in the STM32MP13
