Andreas Böhler 3c152904c2 realtek: add fan controller support to D-Link DGS-1210-28MP 
The DGS-1210-28MP has a LM63 fan controller connected via i2c of the
RTL8231. The clock line is always low if the property
i2c-gpio,scl-open-drain is not set; with this property, the GPIO pin is
force-drive and the clock works as expected.

The LM63 is not configured by U-Boot, thus only manual fan control is
possible by settings pwm1_enable to "1" and writing the desired values to
pwm1.

The OEM firmware drives the fan from user mode and sets it up like this:

// PWM LUT/value r/w, PWM Clock = 1.4kHz
0x4a 0x28
// Tachometer spinup disabled, spin-up cycles bypassed
0x4b 0x00
// PWM Frequency = default
0x4d 0x17
// PWM Value (28)
0x4c 0x1c
// If > 0 C, use
0x50 0x00
// PWM = 28
0x51 0x1c
// If > 51 C, use
0x52 0x33
// PWM = 44
0x53 0x2e
// Set hysteresis to 100 = default
0x4f 0x03
// Turn on automatic mode and w/p the LUT values
0x4a 0x08

A thread in the OEM firmware polls the ALERT status register for fan
failures.

Unfortunately, the lm63 kernel driver does not perform any initialization
of the chip and it does not support changing some config registers (like
PWM frequency or LUT). Hence, we are stuck with the defaults and need to do
fan control in software.

OpenWrt logo

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.

Sunshine!

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

  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 GNU/Linux kernel & all chosen applications for your target system.

Related Repositories

The main repository uses multiple sub-repositories to manage packages of 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.

  • LuCI Web Interface: Modern and modular interface to control the device via a web browser.

  • OpenWrt Packages: Community repository of ported packages.

  • OpenWrt Routing: Packages specifically focused on (mesh) routing.

  • OpenWrt Video: Packages specifically focused on display servers and clients (Xorg and Wayland).
