Subject: [PATCH v7 3/3] arm64: dts: st: set rcc as an access-controller
Date: Mon, 22 Sep 2025 10:12:20 +0200 [thread overview]
Message-ID: <20250922-b4-rcc-upstream-v7-3-2dfc4e018f40@gmail.com> (raw)

From: Clément Le Goffic <clement.legoffic@foss.st.com>
RCC now implements firewall access ops to check the access to
resources. Allow client nodes to query the RCC with one firewall ID.
