Subject: [PATCH 13/15] ARM: dts: sun8i: r40: Add clock accuracy for external oscillators
Date: Wed, 28 Nov 2018 17:30:11 +0800 [thread overview]
Message-ID: <20181128093013.24442-15-wens@csie.org> (raw)
In-Reply-To: <20181128093013.24442-1-wens@csie.org>
The R40 datasheet specifies a tolerance range for the external
oscillators used. Add them to the device tree as the clock accuracy.
