[PATCH 2/7] dt-bindings: stm32: add kernel clocks for ETR and STM

From: Gabriel Fernandez

Date: Fri Oct 23 2026 - 09:31:07 EST


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).

Also rename the bus clocks according to the reference manual,
without changing their values: CK_BUS_STM500 into CK_BUS_STM,
CK_SCMI_STM500 into CK_SCMI_BUS_STM and CK_SCMI_ETR into
CK_SCMI_BUS_ETR.
