Subject: [PATCH] arm64: dts: rockchip: add gpio-line-names to rk3308-rock-pi-s
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.
