Subject: [PATCH v3 1/5] rockchip: Add cpu-info
Date: Mon, 30 Dec 2019 00:37:22 +0530 [thread overview]
Message-ID: <20191229190726.29266-2-jagan@amarulasolutions.com> (raw)
In-Reply-To: <20191229190726.29266-1-jagan-dyjBcgdgk7Pe9wHmmfpqLFaTQe2KTcn/@public.gmane.org>
Add cpu information for rockchip soc.
This would help to print the SoC family number, with
associated temparature, clock and reason for reset etc.
