This device implements the IM120417002 colors shield v1.1 for Arduino

a simple display of an 8x8 RGB matrix.
This color shield can be plugged on the Arduino board (or the
B-L475E-IOT01A board) to drive an 8x8 RGB led matrix.
Nice. Do you have an example? Or better, a test :)
This RGB led matrix takes advantage of retinal persistance to
seemingly display different colors in each row.
It'd be convenient to set the QEMU console's refresh rate
in order to ensure that the delay before turning off rows
(2 frames currently) isn't too short. However
`dpy_ui_info_supported(s->console)` can't be used.
Cc'ing Marc-André Lureau.
I saw that Kconfig configurable components aren't visible in C files,
does that mean it's impossible to make the DM163 device optional when
using the B-L475E-IOT01A board?
You could (but shouldn't) use for build-time:
#include CONFIG_DEVICES
But better at run-time using [module_]object_class_by_name().
