Usage of the clock-frequency property for camera sensors is discouraged in favour of using assigned-clock-rates (and assigned-clock-parents where needed). Mark the property as deprecated. Update the examples accordingly. In DT examples where the sensor input clock appears to come from a programmable clock generator, replace clock-frequency by the assigned-clocks and assigned-clock-rates properties. Otherwise, just drop clock-frequency.

CCS (Camera Command Set) is a raw Bayer camera sensor standard defined by the
|
|
MIPI Alliance; see
|
|
<URL:https://www.mipi.org/specifications/camera-command-set>.
|
|
|
|
SMIA (Standard Mobile Imaging Architecture) is an image sensor standard
|
|
defined jointly by Nokia and ST. SMIA++, defined by Nokia, is an extension of
|
|
that.
