[PATCH 3/3] arm64: dts: ten64: provide gpio-line-names for all system gpios

[Mathew McBride]

There are GPIOs on the Ten64 board which are intended to be
user controlled, as well as some that are used for system functions
(such as SFP control lines and associated LEDs).

Providing the gpio-line-names will be useful to users of the board,
for example, in the /sys/kernel/debug/gpio listing.

The master GPIO list for the board can be viewed here:
