Hello,

I agree that there doesn't seem to any API for it in the Zephyr driver.

Though according to Adafruit, it is preferable to use the Enable pin instead apparently: "For ultra-low power usages, the onboard 3.3V regulator has the Enable pin brought out so you can shut down the power to the SRAM, MicroSD, and display."

Regards,

Elfving

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.
