- Subject: [PATCH] BCM2708: Add core Device Tree support
- MIME-Version: 1.0
- Content-Type: text/plain; charset=UTF-8
- Content-Transfer-Encoding: 8bit
- Add the bare minimum needed to boot BCM2708 from a Device Tree.
- Signed-off-by: Noralf Tronnes <[email protected]>
- BCM2708: DT: change 'axi' nodename to 'soc'
- Change DT node named 'axi' to 'soc' so it matches ARCH_BCM2835.
- The VC4 bootloader fills in certain properties in the 'axi' subtree,
- but since this is part of an upstreaming effort, the name is changed.
- Signed-off-by: Noralf Tronnes [email protected]
- BCM2708_DT: Correct length of the peripheral space
- Use dts-dirs feature for overlays.
- The kernel makefiles have a dts-dirs target that is for vendor subdirectories.
- Using this fixes the install_dtbs target, which previously did not install the overlays.
- BCM270X_DT: configure I2S DMA channels
- Signed-off-by: Matthias Reichl <[email protected]>
- BCM270X_DT: switch to bcm2835-i2s
- I2S soundcard drivers with proper devicetree support (i.e. not linking
- to the cpu_dai/platform via name but to cpu/platform via of_node)
- will work out of the box without any modifications.
- When the kernel is compiled without devicetree support the platform
- code will instantiate the bcm2708-i2s driver and I2S soundcard drivers
- will link to it via name, as before.

- SDIO-overlay: add poll_once-boolean parameter
- Add paramter to toggle sdio-device-polling
- done every second or once at boot-time.

- BCM270X_DT: Make mmc overlay compatible with current firmware
- The original DT overlay logic followed a merge-then-patch procedure,
- i.e. parameters are applied to the loaded overlay before the overlay
- is merged into the base DTB. This sequence has been changed to
- patch-then-merge, in order to support parameterised node names, and
- to protect against bad overlays. As a result, overrides (parameters)
- must only target labels in the overlay, but the overlay can obviously target nodes in the base DTB.
- mmc-overlay.dts (that switches back to the original mmc sdcard
- driver) is the only overlay violating that rule, and this patch
- fixes it.
- bcm270x_dt: Use the sdhost MMC controller by default
- The "mmc" overlay reverts to using the other controller.
- squash: Add cprman to dt
- BCM270X_DT: Use clk_core for I2C interfaces
- BCM270X_DT: Use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi
- The mainline Device Tree files are quite close to downstream now.
- Let's use bcm283x.dtsi, bcm2835.dtsi and bcm2836.dtsi as base files
- for our dts files.
- Mainline dts files are based on these files:
- bcm2835-rpi.dtsi
- bcm2835.dtsi bcm2836.dtsi
- bcm283x.dtsi
- Current downstream are based on these:
- bcm2708.dtsi bcm2709.dtsi bcm2710.dtsi
- bcm2708_common.dtsi
- This patch introduces this dependency:
- bcm2708.dtsi bcm2709.dtsi
- bcm2708-rpi.dtsi
- bcm270x.dtsi
- bcm2835.dtsi bcm2836.dtsi
- bcm283x.dtsi
- And:
- bcm2710.dtsi
- bcm2708-rpi.dtsi
- bcm270x.dtsi
- bcm283x.dtsi
- bcm270x.dtsi contains the downstream bcm283x.dtsi diff.
- bcm2708-rpi.dtsi is the downstream version of bcm2835-rpi.dtsi.
- Other changes:
- - The led node has moved from /soc/leds to /leds. This is not a problem
- since the label is used to reference it.
- - The clk_osc reg property changes from 6 to 3.
- - The gpu nodes has their interrupt property set in the base file.
- - the clocks label does not point to the /clocks node anymore, but
- points to the cprman node. This is not a problem since the overlays
- that use the clock node refer to it directly: target-path = "/clocks";
- - some nodes now have 2 labels since mainline and downstream differs in
- this respect: cprman/clocks, spi0/spi, gpu/vc4.
- - some nodes doesn't have an explicit status = "okay" since they're not
- disabled in the base file: watchdog and random.
- - gpiomem doesn't need an explicit status = "okay".
- - bcm2708-rpi-cm.dts got the hpd-gpios property from bcm2708_common.dtsi,
- it's now set directly in that file.
- - bcm2709-rpi-2-b.dts has the timer node moved from /soc/timer to /timer.
- - Removed clock-frequency property on the bcm{2709,2710}.dtsi timer nodes.

- BCM270X_DT: Add a .dtbo target, use for overlays
- Change the filenames and extensions to keep the pre-DDT style of
- overlay (<name>-overlay.dtb) distinct from new ones that use a
- different style of local fixups (<name>.dtbo), and to match other
- platforms.
- The RPi firmware uses the DDTK trailer atom to choose which type of
- overlay to use for each kernel.

- BCM270X_DT: Don't generate "linux,phandle" props
- The EPAPR standard says to use "phandle" properties to store phandles,
- rather than the deprecated "linux,phandle" version. By default, dtc
- generates both, but adding "-H epapr" causes it to only generate
- "phandle"s, saving some space and clutter.

- BCM270X_DT: Add overlay for enc28j60 on SPI2
- Works on SPI2 for compute module
- BCM270X_DT: Add midi-uart0 overlay
- MIDI requires 31.25kbaud, a baudrate unsupported by Linux. The
- midi-uart0 overlay configures uart0 (ttyAMA0) to use a fake clock
- so that requesting 38.4kbaud actually gets 31.25kbaud.
- Signed-off-by: Phil Elwell <[email protected]>
- BCM270X_DT: Add i2c-sensor overlay
- The i2c-sensor overlay is a container for various pressure and
- temperature sensors, currently bmp085 and bmp280. The standalone
- bmp085_i2c-sensor overlay is now deprecated.
- Signed-off-by: Phil Elwell <[email protected]>
- BCM270X_DT: overlays/*-overlay.dtb -> overlays/*.dtbo (#1752)
- We now create overlays as .dtbo files.
- build: support for .dtbo files for dtb overlays
- Kernel 4.4.6+ on RaspberryPi support .dtbo files for overlays, instead of .dtb.
- Patch the kernel, which has faulty rules to generate .dtbo the way yocto does

- and will probably let peeople that want to choose a larger CMA
- allocation (particularly on pi0/1).

- +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.
- +

- +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
- +

- + default 'none' (LED is user-controlled).
- + Some possible triggers:
- + cpu - CPU load (all CPUs)
- + cpu0 - CPU load of first CPU.
- + mmc - disk activity (all disks)
- + panic - turn on on kernel panic
- + heartbeat - indicate system health
- + gpio - connect to a GPIO input pin (note:
- + currently the GPIO PIN can not be set
- + using overlay parameters, must be
- + done in userspace, see examples above.
- + active_low Set to 1 to turn invert the LED control
- + (writing 0 to /sys/class/leds/XXX/brightness

- +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.
- +
- + 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
- + timeout_ms Specify (in ms) how long the kernel waits for
- + power-down before issuing a WARN (default 3000).
- +
- +
- +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".

- +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.

- + *
- + * 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 |

- + * 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]

- +// dtparams:
- +// sx150<x>-<n>-<m> - Enables SX150X device on I2C#<n> with slave address <m>. <x> may be 1-9.
- +// <n> may be 0 or 1. Permissible values of <m> (which is denoted in hex)
- +// depend on the device variant.
- +// For SX1501, SX1502, SX1504 and SX1505, <m> may be 20 or 21.
- +// For SX1503 and SX1506, <m> may be 20.
- +// For SX1507 and SX1509, <m> may be 3E, 3F, 70 or 71.
- +// For SX1508, <m> may be 20, 21, 22 or 23.
- +// sx150<x>-<n>-<m>-int-gpio - Integer, enables interrupts on SX150X device on I2C#<n> with slave address <m>,
- +// specifies the GPIO pin to which NINT output of SX150X is connected.
- +//
- +//
- +// Example 1: A single SX1505 device on I2C#1 with its slave address set to 0x20 and NINT output connected to GPIO25:
- +// dtoverlay=sx150x:sx1505-1-20,sx1505-1-20-int-gpio=25
- +//
- +// Example 2: Two SX1507 devices on I2C#0 with their slave addresses set to 0x3E and 0x70 (interrupts not used):
- +// dtoverlay=sx150x:sx1507-0-3E,sx1507-0-70
