Subject: [PATCH 13/15] ARM: dts: sun8i: r40: Add clock accuracy for external oscillators
Date:   Wed, 28 Nov 2018 17:30:11 +0800
Message-Id: <20181128093013.24442-15-wens@csie.org>

Precedence: bulk

The R40 datasheet specifies a tolerance range for the external
oscillators used. Add them to the device tree as the clock accuracy.
