Subject: [PATCH 1/3] ARM: dts: sun8i: Enable ARM architected timer on A23
Date: Wed, 18 Mar 2015 11:24:00 +0800 [thread overview]
Message-ID: <1426649042-30547-2-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1426649042-30547-1-git-send-email-wens@csie.org>
The A23 SoC has the architected timer, but the existing firmware from
Allwinner does not set CNTFRQ at all.
Signed-off-by: Chen-Yu Tsai <wens@csie.org>
