Subject: [PATCH 07/11] arm: dts: stm32: enable the debug bus on stm32mp1x boards
Date: Fri, 9 Jan 2026 11:55:07 +0100	[thread overview]
Message-ID: <20260109-debug_bus-v1-7-8f2142b5a738@foss.st.com> (raw)
In-Reply-To: <20260109-debug_bus-v1-0-8f2142b5a738@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.
