Subject: [PATCH v2 2/3] media: dt-bindings: media: i2c: imx219: document clock-frequency property
Date: Sun,  6 Dec 2020 18:27:19 +0100
Message-ID: <20201206172720.9406-2-michael.srba@seznam.cz> (raw)
In-Reply-To: <20201206172720.9406-1-michael.srba@seznam.cz>

From: Michael Srba <Michael.Srba@seznam.cz>

This patch documents the clock-frequency property, which allows the driver
to change the clock frequency from it's default value.
