From 7f8802f2d2ed67ffbac9264f946a52507f749e19 Mon Sep 17 00:00:00 2001 From: Akshu Agrawal Date: Fri, 31 Jul 2020 19:06:03 +0530 Subject: [PATCH] ACPI: APD: Add a fmw property is_raven Since there is slight difference in AMD RV based soc in misc clk architecture. The fmw property will help in differentiating the SoCs. Signed-off-by: Akshu Agrawal Signed-off-by: Rafael J.
