Subject: [PATCH 2/3] arm64: dts: s32g: add SCMI firmware node
Date: Fri, 19 Jan 2024 15:02:29 +0200 [thread overview]
Message-ID: <20240119130231.2854146-3-ghennadi.procopciuc@oss.nxp.com> (raw)
In-Reply-To: <20240119130231.2854146-1-ghennadi.procopciuc@oss.nxp.com>
From: Ghennadi Procopciuc <ghennadi.procopciuc@nxp.com>
Linux controls the clocks over SCMI on S32G SoCs. Therefore,
add the SCMI device tree node and the reserved region for SCMI
messages.
