Subject: [PATCH] ARM: shmobile: armadillo800eva dts: Correct extal1 frequency to 24 MHz
Date: Fri, 18 Dec 2015 10:51:36 +0000 [thread overview]
Message-ID: <1450435896-6026-1-git-send-email-geert+renesas@glider.be> (raw)
On r8a7740/armadillo, actual clock rates are ca. 4% lower than reported
by /sys/kernel/debug/clk/clk_summary. Correct the extal1 frequency from
25 MHz to 24 MHz to fix this.
This matches the Armadillo-800 EVA Product Manual, which claims the main
crystal runs at 24 MHz, and the old legacy/reference board code.
Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be>
