Subject: [PATCH v2 0/4] auxdisplay: 7 segment LED display
Date: Wed, 28 Feb 2024 10:22:40 +1300 [thread overview]
Message-ID: <20240227212244.262710-1-chris.packham@alliedtelesis.co.nz> (raw)
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.
