+ * PiFace Digital, Device Tree Overlay.
+ * Copyright (C) 2020 Thomas Preston <thomas.preston@codethink.co.uk>
+ *
+ * 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]

+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.

+                                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 Pi 3B, 3B+, 3A+ and 4B, use the 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

+                                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.
