Subject: [PATCH v3 02/19] dt-bindings: stm32: stm32mp25: add `access-controller-cell` property
Date: Tue, 22 Jul 2025 16:03:19 +0200 [thread overview]
Message-ID: <20250722-ddrperfm-upstream-v3-2-7b7a4f3dc8a0@foss.st.com> (raw)
In-Reply-To: <20250722-ddrperfm-upstream-v3-0-7b7a4f3dc8a0@foss.st.com>
RCC is able to check the availability of a clock.
Allow to query the RCC with a firewall ID.
