Previously, gpio_switch only accepts GPIO pin number as input. Once a GPIO pin is exported and named by device tree, its pin state cannot be configured and saved across reboots by UCI. This patch adds support for named GPIO pins. Thus GPIO pin can be exported by device tree with active high/low correctly configured, having human-readable name in /sys/class/gpio/ is also now possible. More importantly, GPIO pins which are referenced by name will be immune from pin mapping breakage while unintentional pin number changes are introduced by kernel or driver updates.

This is the buildsystem for the OpenWrt Linux distribution.
To build your own firmware you need a Linux, BSD or MacOSX system (case
sensitive filesystem required). Cygwin is unsupported because of the lack
of a case sensitive file system.
You need gcc, binutils, bzip2, flex, python3.5+, perl, make, find, grep, diff,
unzip, gawk, getopt, subversion, libz-dev and libc headers installed.
1. Run "./scripts/feeds update -a" to obtain all the latest package definitions
defined in feeds.conf / feeds.conf.default
2. Run "./scripts/feeds install -a" to install symlinks for all obtained
packages into package/feeds/
3. Run "make menuconfig" to select your preferred configuration for the
toolchain, target system & firmware packages.
4. Run "make" to build your firmware. This will download all sources, build
the cross-compile toolchain and then cross-compile the Linux kernel & all
chosen applications for your target system.
Sunshine!
