Letting you decide what you wish to do for #96524 (comment) but otherwise LGTM!
Very sharp indeed! 😯

This could be -ENODEV based on grep -R -A2 '!device_is_ready' drivers/, but really I never know which errno to pick!

@VynDragon You shoud provide an explanation when changing/removing PR assignee, will provide one for this instance. PR concerns display drivers mainly, Tests' change is minor & trivial, hence add Display collaborator as assignee. |

well usually nashif unassign themselves silently... |
I guess an assignee does not have to explain themselves when removing their assignment. |
|
@VynDragon - needs a rebase to fix merge conflicts. |

Introduces ST730x series of display controllers.
These displays are epaper-like but with much higher refresh rate. They appear to have similar construction to epaper and lack a contrast control. Their readability is great until framerate is increased, then it drops massively at 51Hz, and looks fine up to 32Hz (the framerate is a specific setting).
(demonstrating loss of contrast at higher framerate)
Tested on shineworld/generic 4.2 inches st7306 and 2.9 inches st7305 B&W panels. This driver doesnt support color but it is a possible future addition as some models support many color and greyscale formats.
