The sensor requires an external clock, and drivers need to access the clock to retrieve its frequency in order to configure the sensor. This makes usage of the clocks property mandatory for a system to work properly. Mark the property as required.

IMX258 is a diagonal 5.867mm (Type 1/3.06) 13 Mega-pixel CMOS active pixel
|
|
type stacked image sensor with a square pixel array of size 4208 x 3120. It
|
|
is programmable through I2C interface. Image data is sent through MIPI
|
|
CSI-2. The sensor exists in two different models, a standard variant
|
|
(IMX258) and a variant with phase detection autofocus (IMX258-PDAF).
|
|
The camera module does not expose the model through registers, so the
|
|
exact model needs to be specified.
