+Introduction
+============
+
+This directory contains Device Tree overlays. 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.dtbo 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.
+

+ (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 "on")
+
+ sd_overclock Clock (in MHz) to use when the MMC framework
+ requests 50MHz
+
+ sd_force_pio Disable DMA support for SD driver (default off)
+
+ sd_pio_limit Number of blocks above which to use DMA for
+ SD card (default 1)
+
+ sd_debug Enable debug output from SD driver (default off)
+
+ uart0 Set to "off" to disable uart0 (default "on")
+
+ uart1 Set to "on" or "off" to enable or disable uart1
+ (default varies)
+
+ 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")
+ N.B. For Pi3 see pi3-act-led overlay.
+
+ 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)
+ N.B. For Pi3 see pi3-act-led overlay.
+
+ 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. It is recommended to only enable those interfaces that are needed.
+ Leaving all interfaces enabled can lead to unwanted behaviour (i2c_vc
+ interfering with Pi Camera, I2S and SPI hogging GPIO pins, etc.)
+ Note also that i2c, i2c_arm and i2c_vc are aliases for the physical
+ interfaces i2c0 and i2c1. Use of the numeric variants is still possible
+ but deprecated because the ARM/VC assignments differ between board
+ revisions. The same board-specific mapping applies to i2c_baudrate,
+ and the other i2c baudrate parameters.

+Troubleshooting
+===============
+
+If you are experiencing problems that you think are DT-related, enable DT
+diagnostic output by adding this to /boot/config.txt:
+
+ dtdebug=on
+
+and rebooting. Then run:
+
+ sudo vcdbg log msg
+
+and look for relevant messages.
