+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.
+
+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.
+

+ 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.
+
+
+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.

+Name: gpio-led
+Info: This is a generic overlay for activating LEDs (or any other component)
+ by a GPIO pin. Multiple LEDs can be set up using multiple calls to the
+ overlay. While there are many existing methods to activate LEDs on the
+ RPi, this method offers some advantages:
+ 1) Does not require any userspace programs.
+ 2) LEDs can be connected to the kernel's led-trigger framework,
+ and drive the LED based on triggers such as cpu load, heartbeat,
+ kernel panic, key input, timers and others.
+ 3) LED can be tied to the input state of another GPIO pin.
+ 4) The LED is setup early during the kernel boot process (useful
+ for cpu/heartbeat/panic triggers).
+
+ Typical electrical connection is:
+ RPI-GPIO.19 -> LED -> 300ohm resister -> RPI-GND
+ The GPIO pin number can be changed with the 'gpio=' parameter.
+
+ To control an LED from userspace, write a 0 or 1 value:
+ echo 1 > /sys/class/leds/myled1/brightness
+ The 'myled1' name can be changed with the 'label=' parameter.
+
+ To connect the LED to a kernel trigger from userspace:
+ echo cpu > /sys/class/leds/myled1/trigger
+ echo heartbeat > /sys/class/leds/myled1/trigger
+ echo none > /sys/class/leds/myled1/trigger
+ To connect the LED to GPIO.26 pin (physical pin 37):
+ echo gpio > /sys/class/leds/myled1/trigger
+ echo 26 > /sys/class/leds/myled1/gpio
+ Available triggers:
+ cat /sys/class/leds/myled1/trigger
+

+Info: Use this overlay to disable GPIO interrupts for GPIOs in bank 0 (0-27),

+
+Name: gpio-poweroff
+Info: Drives a GPIO high or low on poweroff (including halt). 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

+
+
+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. Systemd versions older than 225 need an udev rule
+ enable listening to the input device:
+
+ ACTION!="REMOVE", SUBSYSTEM=="input", KERNEL=="event*", \
+ SUBSYSTEMS=="platform", DRIVERS=="gpio-keys", \
+ ATTRS{keys}=="116", TAG+="power-switch"
+
+ Alternatively this event can be handled also on systems without
+ systemd, just by traditional SysV init daemon. 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. The default
+ configuration uses GPIO3 with a pullup, so if you connect a
+ button between GPIO3 and GND (pin 5 and 6 on the 40-pin header),
+ you get a shutdown and power-up button. Please note that
+ Raspberry Pi 1 Model B rev 1 uses GPIO1 instead of GPIO3.
+Load: dtoverlay=gpio-shutdown,<param>=<val>
+Params: gpio_pin GPIO pin to trigger on (default 3)

+
+ active_low When this is 1 (active low), a falling
+ edge generates a key down event and a
+ rising edge generates a key up event.
+ When this is 0 (active high), this is
+ reversed. The default is 1 (active low).
+
+ gpio_pull Desired pull-up/down state (off, down, up)
+ Default is "up".
+
+ Note that the default pin (GPIO3) has an
+ external pullup. Same applies for GPIO1

+ Some notable differences with the DRM driver compared to fbtft:
+ - The display is turned on when it's first used and not on driver load
+ as with fbtft. So if nothing uses the display it stays off.
+ - Can run with a higher SPI clock increasing framerate. This is possible
+ since the driver avoids messing up the controller configuration due to
+ transmission errors by running config commands at 10MHz and only pixel
+ data at full speed (occasional pixel glitch might occur).
+ - PWM backlight is supported.

+ *
+ * The PiFace Digital is a convenient breakout board for the Microchip mcp23s17
+ * SPI GPIO port expander.
+ *
+ * The first eight GPIOs 0..7 (bank A) are connected to eight output terminals
+ * and LEDs, plus two relays on the first two outputs. These output loads are
+ * active-high.
+ *
+ * The next eight GPIOs 8..15 (bank B) are connected to eight input terminals
+ * with four on-board switches connecting them to ground. Inputs devices are
+ * therefore expected to bridge terminals to ground, so the mcp23s17 pullups are
+ * activated for GPIO bank B.
+ *
+ * On PiFace Digital, the mcp23s17 is connected to the Raspberry Pi's SPI0 CS0
+ * bus. Each SPI bus supports up to eight addressable child devices. The PiFace
+ * Digital only supports addresses 0-4, which can be configured by jumpers JP1
+ * and JP2.
+ *
+ * You can tell the driver about these jumper configurations with the
+ * spi-present-mask bitmask:
+ *
+ * | JP1 | JP2 | dtoverlay line in /boot/config.txt |
+ * | --- | --- | ------------------------------------------ |
+ * | 0 | 0 | dtoverlay=pifacedigital |
+ * | 0 | 0 | dtoverlay=pifacedigital:spi-present-mask=1 |
+ * | 0 | 1 | dtoverlay=pifacedigital:spi-present-mask=2 |
+ * | 1 | 0 | dtoverlay=pifacedigital:spi-present-mask=4 |
+ * | 1 | 1 | dtoverlay=pifacedigital:spi-present-mask=8 |
+ *
+ * # Example
+ * Set the dtoverlay config in /boot/config.txt and power off the Raspberry Pi:
+ *
+ * $ grep pifacedigital /boot/config.txt
+ * dtoverlay=pifacedigital
+ * $ sudo systemctl poweroff
+ *
+ * Attach the PiFace Digital and power on the Raspberry Pi.
+ * Then use the libgpiod tools to query the device:
+ *
+ * $ sudo apt install gpiod
+ * $ gpiodetect | grep mcp23s17
+ * gpiochip2 [mcp23s17.0] (16 lines)
+ *
+ * Set GPIO outputs 0, 2 and 5:
+ *
+ * $ gpioset gpiochip2 0=1 2=1 5=1
+ *
+ * Get GPIO status (input GPIO 8..15 are high, because they are active-low):
+ *
+ * $ gpioget gpiochip2 {8..15}
+ * 1 1 1 1 1 1 1 1
+ *
+ * And even monitor interrupts:
+ *
+ * $ gpiomon gpiochip2 {8..15}
+ * event: FALLING EDGE offset: 11 timestamp: [1597361662.926741667]
+ * event: RISING EDGE offset: 11 timestamp: [1597361663.062555051]
