+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).
+
+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.

+ 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.
+
+
+Name: act-led
+Info: Pi 3B, 3B+, 3A+ and 4B use a GPIO expander to drive the LEDs which can
+ only be accessed from the VPU. There is a special driver for this with a
+ separate DT node, which has the unfortunate consequence of breaking the
+ act_led_gpio and act_led_activelow dtparams.
+ This overlay changes the GPIO controller back to the standard one and
+ restores the dtparams.

+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.
+

+This is only meant to be a quick introduction to the subject of Device Tree on
+Raspberry Pi. There is a more complete explanation here:

+ which has the unfortunate consequence of breaking the act_led_gpio and
+ act_led_activelow dtparams.
+
+ This overlay changes the GPIO controller back to the standard one and
+ restores the dtparams.

+// s08-spi<n>-<m>-present - 4-bit integer, bitmap indicating MCP23S08 devices present on SPI<n>, CS#<m>.
+// s17-spi<n>-<m>-present - 8-bit integer, bitmap indicating MCP23S17 devices present on SPI<n>, CS#<m>.
+// s08-spi<n>-<m>-int-gpio - integer, enables interrupts on a single MCP23S08 device on SPI<n>, CS#<m>, specifies the GPIO pin to which INT output is connected.
+// s17-spi<n>-<m>-int-gpio - integer, enables mirrored interrupts on a single MCP23S17 device on SPI<n>, CS#<m>, specifies the GPIO pin to which either INTA or INTB output is connected.
+//
+// If devices are present on SPI1 or SPI2, those interfaces must be enabled with one of the spi1-1/2/3cs and/or spi2-1/2/3cs overlays.
+// If interrupts are enabled for a device on a given CS# on a SPI bus, that device must be the only one present on that SPI bus/CS#.
+//
+// Example 1: A single MCP23S17 device on SPI0, CS#0 with its SPI addr set to 0 and INTA output connected to GPIO25:
+// dtoverlay=mcp23s17:s17-spi0-0-present=1,s17-spi0-0-int-gpio=25
+//
+// Example 2: Two MCP23S08 devices on SPI1, CS#0 with their addrs set to 2 and 3. Three MCP23S17 devices on SPI1, CS#1 with their addrs set to 0, 1 and 7:
+// dtoverlay=spi1-2cs
+// dtoverlay=mcp23s17:s08-spi1-0-present=12,s17-spi1-1-present=131
