Subject: [PATCH 02/11] dt-bindings: pinctrl: document access-controllers property for stm32 HDP
Date: Fri, 9 Jan 2026 11:55:02 +0100 [thread overview]
Message-ID: <20260109-debug_bus-v1-2-8f2142b5a738@foss.st.com> (raw)
In-Reply-To: <20260109-debug_bus-v1-0-8f2142b5a738@foss.st.com>
HDP being functional depends on the debug configuration on the platform
that can be checked using the access-controllers property, document it.
