With the recent backport of the common PHY properties infrastructure
(phy-common-props and the phy_get_manual_{rx,tx}_polarity() helpers) to
OpenWrt, the generic `{rx,tx}-polarity` device tree properties are now
usable for the Realtek PCS driver. Switch the driver and all affected
boards from the local vendor-specific `realtek,pnswap-{rx,tx}` booleans
to the common properties.
Add a `config_polarity` SerDes op (implemented by RTL930x and RTL931x;
RTL838x/RTL839x polarity support not yet added) and a generic wrapper
that resolves the requested polarity via phy_get_manual_{rx,tx}_polarity()
and dispatches to the op. Variants without the op silently accept the
default polarity but warn when a non-default polarity is requested,
since that cannot be honored.
Move the polarity programming out of the variant setup_serdes callbacks
into rtpcs_pcs_config, so it runs before setup_serdes. This matches the
ordering used by the vendor SDK, which configures polarity first.
Update all board DTS files that previously used `realtek,pnswap-{rx,tx}`
to the new `{rx,tx}-polarity = <PHY_POL_INVERT>` property, and select
PHY_COMMON_PROPS from Kconfig.
Each SerDes now retains its DT node for later polarity lookup. Use
for_each_child_of_node_scoped for the iterator, and register a
devm_add_action_or_reset for each stored reference so it is released on
unbind or probe failure.

OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application. For developers, OpenWrt is the framework to build an application without having to build a complete firmware around it; for users this means the ability for full customization, to use the device in ways never envisioned.

Download
Built firmware images are available for many architectures and come with a package selection to be used as WiFi home router. To quickly find a factory image usable to migrate from a vendor stock firmware to OpenWrt, try the Firmware Selector.
If your device is supported, please follow the Info link to see install instructions or consult the support resources listed below.
An advanced user may require additional or specific package. (Toolchain, SDK, ...) For everything else than simple firmware download, try the wiki download page:
Development
To build your own firmware you need a GNU/Linux, BSD or macOS system (case sensitive filesystem required). Cygwin is unsupported because of the lack of a case sensitive file system.
Requirements
You need the following tools to compile OpenWrt, the package names vary between distributions. A complete list with distribution specific packages is found in the Build System Setup documentation.
binutils bzip2 diff find flex gawk gcc-6+ getopt grep install libc-dev libz-dev
make4.1+ perl python3.7+ rsync subversion unzip which
Quickstart
-
Run
./scripts/feeds update -ato obtain all the latest package definitions defined in feeds.conf / feeds.conf.default -
Run
./scripts/feeds install -ato install symlinks for all obtained packages into package/feeds/ -
Run
make menuconfigto select your preferred configuration for the toolchain, target system & firmware packages. -
Run
maketo build your firmware. This will download all sources, build the cross-compile toolchain and then cross-compile the GNU/Linux kernel & all chosen applications for your target system.

different categories. All packages are installed via the OpenWrt package
manager called opkg. If you're looking to develop the web interface or port
packages to OpenWrt, please find the fitting repository below.
