[PATCH v2 0/4] auxdisplay: 7 segment LED display

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

At this point I've decided not to pursue supporting >1 character. I had
a look at what would be required to add a devm_fwnode_gpiod_get_array()
and got bogged down in OF and ACPI code for counting GPIOs.
