Subject: [PATCH v2 3/4] ARM: dts: marvell: Add 7 segment LED display on x530
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@...iedtelesis.co.nz>

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