Waveshare e-paper with ssd16xx driver

[Tiit]

Hi

I would like to know, if Zephyr-s ssd16xx driver supports display driver board power supply control? I see from Zephyr documentation ( solomon,ssd16xxfb (on spi bus) — Zephyr Project Documentation (nordicsemi.com)  two parameters (supply-gpios and vin-gpios), but if I look into the ssd16xx driver, I don't see that there are these used in any function.

I would like to switch my display board off, if there is no need to change information on display (board has ENABLE input for that). I think I can handle it on my code also, but if the driver supports that, would that be nice.

Hi Tiit,

Exactly which display are you using?

I had a brief look at the driver and could also not(at first glance) see supply-gpios and vin-gpios being used. I am taking a better look and will get back to you.
