Subject: [PATCH v4 2/8] dt-bindings: stm32: add kernel clocks for ETR and STM
Date: Fri, 6 Nov 2026 17:16:32 +0100 [thread overview]
Message-ID: <20261106-ups_mp25_clk_update-v4-2-9e32b817c38d@foss.st.com> (raw)
In-Reply-To: <20261106-ups_mp25_clk_update-v4-0-9e32b817c38d@foss.st.com>
Add the kernel clocks of the ETR (CK_KER_ETR) and of the STM
(CK_KER_STM) for STM32MP25, with the matching SCMI clocks
(CK_SCMI_KER_ETR and CK_SCMI_KER_STM).
These are the trace (ATB) clocks of the CoreSight Embedded
Trace Router and System Trace Macrocell, while the bus clocks
only provide register access (APB).
