Add names to the pins of the general-purpose expansion header as given
in the Radxa GPIO page[1] following the conventions in the kernel
documentation[2] to make it easier for users to correlate the pins with
functions when using utilities such as 'gpioinfo'.

The formatting should be a bit different, i.e. all lines following 
"gpio-line-names =" and providing the value should be indented one tab 
position further.

Applied, thanks!

[1/1] arm64: rockchip: dts: rk3328-rock-pi-e: add gpio-line-names
      commit: 799637dfadb092d1732afacea42f67a6f1621fb4

I've indented the gpio lines by one tab as suggested by Dragan.
And also moved the &gpio {} references to their correct position
in the file.

Please sort phandle-references alphabetically and not just add them
to the bottom of the file.


Best regards,
