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. --- [1] - https://lore.kernel.org/lkml/2a8d19ee-b18b-4b7c-869f-7d601cea30b6@alliedtelesis.co.nz/ Chris Packham (4): auxdisplay: Add 7 segment LED display driver dt-bindings: auxdisplay: Add bindings for generic 7 segment LED ARM: dts: marvell: Add 7 segment LED display on x530 ARM: dts: marvell: Indicate USB activity on x530 .../auxdisplay/generic-gpio-7seg.yaml | 40 ++++++ .../boot/dts/marvell/armada-385-atl-x530.dts | 22 +++- drivers/auxdisplay/Kconfig | 10 ++ drivers/auxdisplay/Makefile | 1 + drivers/auxdisplay/seg-led.c | 119 ++++++++++++++++++ 5 files changed, 191 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/auxdisplay/generic-gpio-7seg.yaml create mode 100644 drivers/auxdisplay/seg-led.c
