Subject: [PATCH v2 3/4] ARM: dts: marvell: Add 7 segment LED display on x530
Date: Wed, 28 Feb 2024 10:22:43 +1300	[thread overview]
Message-ID: <20240227212244.262710-4-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20240227212244.262710-1-chris.packham@alliedtelesis.co.nz>

The Allied Telesis x530 products have a 7 segment LED display which is
used for node identification when the devices are stacked. Represent
this as a gpio-7seg device.

Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>

Notes:
    Changes in v2:
    - Use compatible = "generic-gpio=7seg" to keep checkpatch.pl happy
