[PATCH] ARM: dts: nuvoton,wpcm450-supermicro-x9sci-ln4f: Add GPIO line names
From: Jonathan Neuschäfer
Date: Tue Nov 01 2022 - 06:29:42 EST
To make gpioinfo output more useful and enable gpiofind usage, add line
names for GPIOs where the function is known.
This patch follows the naming convention defined for OpenBMC, as much as
possible:
