1.8V and 2.8V power lines on libretech-all-h3-cc-h2+

Rhythm

Hi,
I couldn't find the power lines for 1.8V and 2.8V in power tree of libretech-all-h3-cc h2+ variant in the schematics.
I would need these because OV5640 camera module requires these voltages for its power-up sequence. Also I couldn't even find any regulators for the same defined in sunxi-libretech-all-h3-cc.dtsi file, but for 1.2V, 3.3V, 5.0V regulators are available.

Please suggest which regulators for GPIOs can be used to feed required voltages to camera sensor.

Thanks

Rhythm

Sorry for the irrelevant question. I didn't knew I can simply define the regulator in dtsi files.

Hi
I'm still not sure if this method works, because updating device tree doesn't even change the voltages at connector pins.
Can somebody please suggest some reference or guide, for how can I get 1.8V, 2.8V and 1.5V power regulators for this board?

Please suggest

One of our engineers is working on the mainline code for this. Should have something shortly.

Okay, so as for now should I assume that I can't get it working and it is the intended behaviour for now?

Rhythm

Hi
Can you please tell me whether a hardware change would be necessary for the same or it will just be the configuration part?
