The data lanes and link frequency were set to match existing Linux driver
limitations, however bindings should be independent of chosen Linux
driver support.
Decouple these properties from the driver to match what is actually
supported by the hardware.
This also fixes DTS example:
ov8856.example.dtb: camera@10: port:endpoint:link-frequencies:0: [360000000] is too short

The Omnivision OV8856 is a high performance, 1/4-inch, 8 megapixel, CMOS
|
|
image sensor that delivers 3264x2448 at 30fps. It provides full-frame,
|
|
sub-sampled, and windowed 10-bit MIPI images in various formats via the
|
|
Serial Camera Control Bus (SCCB) interface. This chip is programmable
|
|
through I2C and two-wire SCCB. The sensor output is available via CSI-2
|
|
serial data output (up to 4-lane).
