   4 Subject: [PATCH] arm64: dts: rockchip: add gpio-line-names to radxa-zero-3
   5
   6 Add names to the pins of the general-purpose expansion header as given
   7 in the Radxa documentation[1] following the conventions in the kernel[2]
   8 to make it easier for users to correlate pins with functions when using
   9 utilities such as 'gpioinfo'.
