I know we have some code ported to the nRF52 for the Arducam mini 2MP which uses SPI (data) and I2C (control) to communicate with the camera. If this is what you look for I will ask if we can make it public.
UPDATE:
Here is an example for PCA10040 or PCA10056 for ArduCAM mini 2MP:
The example do not use the standard SDK drivers, but custom ones written in C++. The cpplib folder have to be placed under nRF5_SDK_13.0.0-1.alpha\components. The ArduCAM folder should be placed under nRF5_SDK_13.0.0-1.alpha\examples\MyProjects or similar folder.
See the ArduCAM::spiTwiInit() function for which pins are used for the ArduCAM mini 2MP. If the VCC and GND pin on the ArduCAM are bent, the module can be directly connected in header P4: P0.22-P0.27 on PCA10040 (nRF52 DK), and P24: P1.09 - P0.13 on PCA10056 (nRF52840 PDK).
Perhaps this code should be in your github repo, to make it easier for people to find.
BTW. i am sure the nRF52 would be able to directly read data from the OV7670 ( because people managed to do it with a 16MHz AVR), but I doubt anyone has the time or enthusiasm to try it on the nRF52.
