From: Stefano Radaelli <stefano.r@variscite.com>
Add support for the OV5640 camera connected to the Sonata carrier
board's first MIPI CSI port.
Describe the sensor on I2C2, its 24 MHz reference clock, fixed supplies,
and reset and power-down signals controlled by the GPIO expander.
Connect the sensor to the MIPI CSI receiver using two data lanes and
enable the receiver and CSI bridge.

Does this board only support ov5640 camera? Suppose ov5640 module also use
for other boards.
Can you refer https://lore.kernel.org/imx/20261011-expulsion-frivolous-690de090cf9d@spud/
to define connectors?
