Subject: [PATCH v2 10/14] ARM: dts: sunxi: h3/h5: Add clock accuracy for external oscillators
Date: Mon, 3 Dec 2018 22:58:21 +0800 [thread overview]
Message-ID: <20181203145825.20511-11-wens@csie.org> (raw)
In-Reply-To: <20181203145825.20511-1-wens@csie.org>
The H3 datasheet specifies a tolerance range for the external
oscillators used. Add them to the device tree as the clock accuracy.
The internal oscillator is left unchanged, as it will be removed later.
