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.

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: 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.

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 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.

|
+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.
|
|
+
|

|
|

|
|
+ 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
|
|

|
|
+ 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.
|
|
+
|
