Subject: [PATCH 14/22] ARM: dts: sun8i: a83t: bananapi-m3: Enable MIPI CSI-2 with OV8865
Date: Fri, 10 Sep 2021 20:41:39 +0200	[thread overview]
Message-ID: <20210910184147.336618-15-paul.kocialkowski@bootlin.com> (raw)
In-Reply-To: <20210910184147.336618-1-paul.kocialkowski@bootlin.com>

From: Kévin L'hôpital <kevin.lhopital@bootlin.com>

The Bananapi M3 supports a camera module which includes an OV8865 sensor
connected via the parallel CSI interface and an OV8865 sensor connected
via MIPI CSI-2.

The I2C2 bus is shared by the two sensors as well as the (active-low)
reset signal, but each sensor has it own shutdown line.
