Camera board • Re: Which GPIO# is used for CAM_GPIO on MIPI port?

Because we are connecting various image sensors with our own board, I'd like to know how to control enable signal.
I'll try to modify the .dts to contro; by cam1_reg.

Are you going through V4L2 drivers now? If so, then the regulator calls I've already pointed you at are the right approach.

But I wonder, from the HW design point of the view, the enable signal on V2 camera board are commonly used to enable the VANA, VDDL and VDIG, right?

Yes, CAM_GPIO is controlling all 3 regulators and the oscillator. See the schematics v2 v3 and hq.
The drivers are set up to be able to control each rail individually as some designs may choose to do so. The unconnected regulator defines are connected to a dummy regulator to avoid the kernel logging messages that the regulator isn't defined and worrying people.
