[PATCH 0/3] auxdisplay: 7 segment LED display

[Chris Packham]

This series adds a driver for a 7 segment LED display.

I'd like to get some feedback on how this could be extended to support >1
character. The driver as presented is sufficient for my hardware which only has
a single character display but I can see that for this to be generically useful
supporting more characters would be desireable.

Earlier I posted an idea that the characters could be represended by
sub-nodes[1] but there doesn't seem to be a way of having that and keeping the
convenience of using devm_gpiod_get_array() (unless I've missed something).
