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. -+ -+The Overlay and Parameter Reference -+=================================== -+ -+N.B. When editing this file, please preserve the indentation levels to make it -+simple to parse programmatically.
