Subject: [PATCH 3/4] ACPI: APD: Add a fmw property is_raven
Date: Mon, 20 Jul 2020 10:34:58 +0530
Message-ID: <20200720050500.23357-4-akshu.agrawal@amd.com> (raw)
In-Reply-To: <20200720050500.23357-1-akshu.agrawal@amd.com>

Since there is slight difference in AMD RV based soc in misc
clk architecture. The fmw property will help in differentiating
the SoCs.
