The camera driver (according also to bindings) registers a clock provider if clock-output-names property is present and later the sensors use registered clocks.
The DTS for S5Pv210 Goni board was incorrectly adding a child node with clock output cells but without clock-output-names property. Although the DTS was compiling (with "/soc/camera/clock-controller: missing or empty reg/ranges property" warning), the clock provider was not registered.
