Device Tree makes it possible ++to support many hardware configurations with a single kernel and without the ++need to explicitly load or blacklist kernel modules. Note that this isn't a ++"pure" Device Tree configuration (c.f. MACH_BCM2835) - some on-board devices ++are still configured by the board support code, but the intention is to ++eventually reach that goal. ++ ++On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By ++default, the Raspberry Pi kernel boots with device tree enabled. You can ++completely disable DT usage (for now) by adding: ++ ++ device_tree= ++ ++to your config.txt, which should cause your Pi to revert to the old way of ++doing things after a reboot. ++ ++In /boot you will find a .dtb for each base platform. This describes the ++hardware that is part of the Raspberry Pi board. The loader (start.elf and its ++siblings) selects the .dtb file appropriate for the platform by name, and reads ++it into memory. At this point, all of the optional interfaces (i2c, i2s, spi) ++are disabled, but they can be enabled using Device Tree parameters: ++ ++ dtparam=i2c=on,i2s=on,spi=on ++ ++However, this shouldn't be necessary in many use cases because loading an ++overlay that requires one of those interfaces will cause it to be enabled ++automatically, and it is advisable to only enable interfaces if they are ++needed. ++ ++Configuring additional, optional hardware is done using Device Tree overlays ++(see below). ++ ++GPIO numbering uses the hardware pin numbering scheme (aka BCM scheme) and ++not the physical pin numbers. ++ ++raspi-config ++============ ++ ++The Advanced Options section of the raspi-config utility can enable and disable ++Device Tree use, as well as toggling the I2C and SPI interfaces. Note that it ++is possible to both enable an interface and blacklist the driver, if for some ++reason you should want to defer the loading. ++ ++Modules ++======= ++ ++As well as describing the hardware, Device Tree also gives enough information ++to allow suitable driver modules to be located and loaded, with the corollary ++that unneeded modules are not loaded. As a result it should be possible to ++remove lines from /etc/modules, and /etc/modprobe.d/raspi-blacklist.conf can ++have its contents deleted (or commented out). ++ ++Using Overlays ++============== ++ ++Overlays are loaded using the "dtoverlay" config.txt setting. As an example, ++consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded ++by writing a magic string comprising a device identifier and an I2C address to ++a special file in /sys/class/i2c-adapter, having first loaded the driver for ++the I2C interface and the RTC device - something like this: ++ ++ modprobe i2c-bcm2835 ++ modprobe rtc-ds1307 ++ echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device ++ ++With DT enabled, this becomes a line in config.txt: ++ ++ dtoverlay=i2c-rtc,ds1307 ++ ++This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node" ++describing the DS1307 I2C device to be added to the Device Tree for the Pi. By ++default it usees address 0x68, but this can be modified with an additional DT ++parameter: ++ ++ dtoverlay=i2c-rtc,ds1307,addr=0x68 ++ ++Parameters usually have default values, although certain parameters are ++mandatory. See the list of overlays below for a description of the parameters ++and their defaults. ++ ++Making new Overlays based on existing Overlays ++============================================== ++ ++Recent overlays have been designed in a more general way, so that they can be ++adapted to hardware by changing their parameters. When you have additional ++hardware with more than one device of a kind, you end up using the same overlay ++multiple times with other parameters, e.g. ++ ++ # 2 CAN FD interfaces on spi but with different pins ++ dtoverlay=mcp251xfd,spi0-0,interrupt=25 ++ dtoverlay=mcp251xfd,spi0-1,interrupt=24 ++ ++ # a realtime clock on i2c ++ dtoverlay=i2c-rtc,pcf85063 ++ ++While this approach does work, it requires knowledge about the hardware design. ++It is more feasible to simplify things for the end user by providing a single ++overlay as it is done the traditional way. ++ ++A new overlay can be generated by using ovmerge utility. ++https://github.com/raspberrypi/utils/blob/master/ovmerge/ovmerge ++ ++To generate an overlay for the above configuration we pass the configuration ++to ovmerge and add the -c flag. ++ ++ ovmerge -c mcp251xfd-overlay.dts,spi0-0,interrupt=25 \ ++ mcp251xfd-overlay.dts,spi0-1,interrupt=24 \ ++ i2c-rtc-overlay.dts,pcf85063 \ ++ >> merged-overlay.dts ++ ++The -c option writes the command above as a comment into the overlay as ++a marker that this overlay is generated and how it was generated. ++After compiling the overlay it can be loaded in a single line. ++ ++ dtoverlay=merged ++ ++It does the same as the original configuration but without parameters. ++ ++The Overlay and Parameter Reference ++=================================== ++ ++N.B.

Using this ++ overlay interferes with the normal power-down sequence, preventing the ++ kernel from resetting the SoC (a necessary step in a normal power-off ++ or reboot). This also disables the ability to trigger a boot by driving ++ GPIO3 low. ++ ++ The GPIO starts in an inactive state. At poweroff time it is driven ++ active for 100ms, then inactive for 100ms, then active again. It is ++ safe to remove the power at any point after the initial activation of ++ the GPIO. ++ ++ Users of this overlay are required to provide an external mechanism to ++ switch off the power supply when signalled - failure to do so results ++ in a kernel BUG, increased power consumption and undefined behaviour. ++Load: dtoverlay=gpio-poweroff,<param>=<val> ++Params: gpiopin GPIO for signalling (default 26) ++ ++ active_low Set if the power control device requires a ++ high->low transition to trigger a power-down. ++ Note that this will require the support of a ++ custom dt-blob.bin to prevent a power-down ++ during the boot process, and that a reboot ++ will also cause the pin to go low. ++ input Set if the gpio pin should be configured as ++ an input. ++ export Set to export the configured pin to sysfs ++ active_delay_ms Initial GPIO active period (default 100) ++ inactive_delay_ms Subsequent GPIO inactive period (default 100) ++ timeout_ms Specify (in ms) how long the kernel waits for ++ power-down before issuing a WARN (default 3000). ++ ++ ++Name: gpio-shutdown ++Info: Initiates a shutdown when GPIO pin changes. The given GPIO pin ++ is configured as an input key that generates KEY_POWER events. ++ ++ This event is handled by systemd-logind by initiating a ++ shutdown.

KEY_POWER event ++ (keycode 116) needs to be mapped to KeyboardSignal on console ++ and then kb::kbrequest inittab action which is triggered by ++ KeyboardSignal from console can be configured to issue system ++ shutdown. Steps for this configuration are: ++ ++ Add following lines to the /etc/console-setup/remap.inc file: ++ ++ # Key Power as special keypress ++ keycode 116 = KeyboardSignal ++ ++ Then add following lines to /etc/inittab file: ++ ++ # Action on special keypress (Key Power) ++ kb::kbrequest:/sbin/shutdown -t1 -a -h -P now ++ ++ And finally reload configuration by calling following commands: ++ ++ # dpkg-reconfigure console-setup ++ # service console-setup reload ++ # init q ++ ++ This overlay only handles shutdown. After shutdown, the system ++ can be powered up again by driving GPIO3 low.
