Subject: [3/4] ACPI: APD: Add a fmw property is_raven
Date: Fri, 31 Jul 2020 19:06:03 +0530 [thread overview]
Message-ID: <20200731133604.12512-4-akshu.agrawal@amd.com> (raw)
In-Reply-To: <20200731133604.12512-1-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.
