Subject: [PATCH] arm64: dts: rockchip: add gpio-line-names to radxa-zero-3
Date: Wed, 19 Jun 2024 21:32:49 -0400 [thread overview]
Message-ID: <20240620013301.33653-1-twoerner@gmail.com> (raw)
Add names to the pins of the general-purpose expansion header as given
in the Radxa documentation[1] following the conventions in the kernel[2]
to make it easier for users to correlate pins with functions when using
utilities such as 'gpioinfo'.
