Subject: [PATCH v5 3/3] ARM: dts: marvell: Add 7-segment LED display on x530
Date: Thu, 7 Mar 2024 12:50:21 +1300 [thread overview]
Message-ID: <20240306235021.976083-4-chris.packham@alliedtelesis.co.nz> (raw)
In-Reply-To: <20240306235021.976083-1-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-7-segment device.
Signed-off-by: Chris Packham <chris.packham@alliedtelesis.co.nz>

Notes:
Changes in v5:
- group GPIO specifiers
Changes in v4:
- Use correct compatible name in commit message
Changes in v3:
- Use compatible = "gpio-7-segment" as suggested by Rob
Changes in v2:
- Use compatible = "generic-gpio-7seg" to keep checkpatch.pl happy
