Subject: [PATCH 3/3] ARM: dts: marvell: Add 7 segment LED display on x530
Date: Mon, 26 Feb 2024 10:34:23 +1300	[thread overview]
Message-ID: <20240225213423.690561-4-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20240225213423.690561-1-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.
