Since commit 98e0500ead ("media: i2c: imx290: Add configurable link
frequency and pixel rate") the driver expects two specific
link-frequency settings 2-lane (445500000, 297000000) and 4-lane
(222750000, 148500000) operation. The driver fails to probe without
these exact settings.
Update the example in the bindings to match this to make it easier for
users to incorporate this sensor in their device tree descriptions
without having to read the driver sources when the driver fails to
probe.

|
|
The Sony IMX290 is a 1/2.8-Inch CMOS Solid-state image sensor with Square
|
|
Pixel, available in either mono or colour variants. It is programmable
|
|
through I2C and 4-wire interfaces.
|
|
|
|
The sensor output is available via CMOS logic parallel SDR output, Low voltage
|
|
LVDS DDR output and CSI-2 serial data output. The CSI-2 bus is the default.
|
|
No bindings have been defined for the other busses.
|
|
|
|
imx290lqr is the full model identifier for the colour variant. "sony,imx290"
|
|
is treated the same as this as it was the original compatible string.
|
|
imx290llr is the mono version of the sensor.
