Subject: [PATCH v4 02/12] dt-bindings: pinctrl: document access-controllers property for stm32 HDP
Date: Thu, 22 Jan 2026 17:19:15 +0100 [thread overview]
Message-ID: <20260122-debug_bus-v4-2-28f0f2a25f2c@foss.st.com> (raw)
In-Reply-To: <20260122-debug_bus-v4-0-28f0f2a25f2c@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.
