Subject: [PATCH v5 08/12] arm: dts: stm32: enable the debug bus on stm32mp1x boards
Date: Fri, 23 Jan 2026 11:39:05 +0100 [thread overview]
Message-ID: <20260123-debug_bus-v5-8-90b670844241@foss.st.com> (raw)
In-Reply-To: <20260123-debug_bus-v5-0-90b670844241@foss.st.com>
On stm32mp1x boards, enable the debug bus so we always try to probe
the debug peripherals, if their status and the debug configuration
allow it.
