Great news!

Does the sensor still hang after 0x2f is written to REG_GRCOM instead ?

Do you have CONFIG_PM_RUNTIME enabled ? Can you try and see it works
if you enable it, without additional changes to the clock handling ?

I hope to eventually prepare the ov9650 sensor driver for mainline. Your
help in making it ready for VER=0x52 would be very much appreciated. :-)
