Subject: [PATCH v2 3/3] [NOT FOR MERGE] ARM: dts: sun8i: a83t: bananapi-m3: Enable OV8865 camera
Date: Fri, 28 Aug 2020 15:11:34 +0200 [thread overview]
Message-ID: <20200828131134.12113-4-kevin.lhopital@bootlin.com> (raw)
In-Reply-To: <20200828131134.12113-1-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 active-low
reset signal but each sensor has it own shutdown line.
The I2c address for the OV8865 is 0x36.
The bus type is hardcoded to 4 due to the lack of available
define usable in the device-tree.
