Subject: [PATCH v5 04/12] bus: stm32_firewall: allow check on different firewall controllers
Date: Fri, 23 Jan 2026 11:39:01 +0100 [thread overview]
Message-ID: <20260123-debug_bus-v5-4-90b670844241@foss.st.com> (raw)
In-Reply-To: <20260123-debug_bus-v5-0-90b670844241@foss.st.com>
Current implementation restricts the check on the firewall controller
being the bus parent. Change this by using the controller referenced
in each firewall queries.
