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). ++ ++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" directive. As an example, consider the ++popular lirc-rpi module, the Linux Infrared Remote Control driver. In the ++pre-DT world this would be loaded from /etc/modules, with an explicit ++"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled, ++this becomes a line in config.txt: ++ ++ dtoverlay=lirc-rpi ++ ++This causes the file /boot/overlays/lirc-rpi-overlay.dtb to be loaded. By ++default it will use GPIOs 17 (out) and 18 (in), but this can be modified using ++DT parameters: ++ ++ dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13 ++ ++Parameters always have default values, although in some cases (e.g. "w1-gpio") ++it is necessary to provided multiple overlays in order to get the desired ++behaviour. See the list of overlays below for a description of the parameters and their defaults. ++ ++The Overlay and Parameter Reference ++=================================== ++ ++Name: <The base DTB> ++Info: Configures the base Raspberry Pi hardware ++Load: <loaded automatically> ++Params: ++ audio Set to "on" to disable the onboard ALSA audio ++ interface (default "off") ++ ++ i2c_arm Set to "on" to enable the ARM's i2c interface ++ (default "off") ++ ++ i2c_vc Set to "on" to enable the i2c interface ++ usually reserved for the VideoCore processor ++ (default "off") ++ ++ i2c An alias for i2c_arm ++ ++ i2c_arm_baudrate Set the baudrate of the ARM's i2c interface ++ (default "100000") ++ ++ i2c_vc_baudrate Set the baudrate of the VideoCore i2c interface ++ (default "100000") ++ ++ i2c_baudrate An alias for i2c_arm_baudrate ++ ++ i2s Set to "on" to enable the i2s interface ++ (default "off") ++ ++ spi Set to "on" to enable the spi interfaces ++ (default "off") ++ ++ random Set to "on" to enable the hardware random ++ number generator (default "off") ++ ++ uart0 Set to "off" to disable uart0 (default "on") ++ ++ watchdog Set to "on" to enable the hardware watchdog ++ (default "off") ++ ++ act_led_trigger Choose which activity the LED tracks. ++ Use "heartbeat" for a nice load indicator. ++ (default "mmc") ++ ++ act_led_activelow Set to "on" to invert the sense of the LED ++ (default "off") ++ ++ act_led_gpio Set which GPIO to use for the activity LED ++ (in case you want to connect it to an external ++ device) ++ (default "16" on a non-Plus board, "47" on a ++ Plus or Pi 2) ++ ++ pwr_led_trigger ++ pwr_led_activelow ++ pwr_led_gpio ++ As for act_led_*, but using the PWR LED. ++ Not available on Model A/B boards. ++ ++ N.B.
