Subject: [PATCH v2 1/3] dt-bindings: bus: add stm32mp21 RIFSC compatible
Date: Thu, 6 Nov 2025 10:31:48 +0100 [thread overview]
Message-ID: <20251106-rifsc_debugfs-v2-1-f90e94ae756d@foss.st.com> (raw)
In-Reply-To: <20251106-rifsc_debugfs-v2-0-f90e94ae756d@foss.st.com>
The STM32MP21x platforms have a slightly different RIFSC. While its
core functionalities are similar, the wiring is not the same. Hence,
declare a new compatible.
