I extensively reproduced the vendor bootloader sequence, but after the boot isn't possible to do the full initialization of the display (at least on Pixel 3, and panel can't be found anywhere else). The downstream, due to having attached touchscreen reusing same supplies, never turns the panel off. Let's do the same.
