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. |

BCM270X_DT: Add i2c-sensor overlay |

temperature sensors, currently bmp085 and bmp280. The standalone |
bmp085_i2c-sensor overlay is now deprecated. |

BCM270X_DT: overlays/*-overlay.dtb -> overlays/*.dtbo (#1752) |

|
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 |

+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. |
+ |
+The Overlay and Parameter Reference |
+=================================== |
+ |
+N.B. When editing this file, please preserve the indentation levels to make it |
+simple to parse programmatically. NO HARD TABS. |

+ |
+Name: <The base DTB> |
+Info: Configures the base Raspberry Pi hardware |
+Load: <loaded automatically> |
+Params: |
+ audio Set to "on" to enable the onboard ALSA audio |
+ interface (default "off") |
+ |
+ i2c_arm Set to "on" to enable the ARM's i2c interface |
+ (default "off") |
+ |
+ i2c_vc Set to "on" to enable the i2c interface |
+ usually reserved for the VideoCore processor |
+ (default "off") |
+ |
+ i2c An alias for i2c_arm |
+ |
+ i2c_arm_baudrate Set the baudrate of the ARM's i2c interface |
+ (default "100000") |
+ |
+ i2c_vc_baudrate Set the baudrate of the VideoCore i2c interface |
+ (default "100000") |
+ |
+ i2c_baudrate An alias for i2c_arm_baudrate |
+ |
+ i2s Set to "on" to enable the i2s interface |
+ (default "off") |
+ |
+ spi Set to "on" to enable the spi interfaces |
+ (default "off") |
+ |
+ random Set to "on" to enable the hardware random |
+ number generator (default "on") |
+ |
+ sd_overclock Clock (in MHz) to use when the MMC framework |
+ requests 50MHz |
+ |
+ sd_force_pio Disable DMA support for SD driver (default off) |
+ |
+ sd_pio_limit Number of blocks above which to use DMA for |
+ SD card (default 1) |
+ |
+ sd_debug Enable debug output from SD driver (default off) |
+ |
+ uart0 Set to "off" to disable uart0 (default "on") |
+ |
+ uart1 Set to "on" or "off" to enable or disable uart1 |
+ (default varies) |
+ |
+ watchdog Set to "on" to enable the hardware watchdog |
+ (default "off") |
+ |
+ act_led_trigger Choose which activity the LED tracks. |
+ 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 Pi3 see pi3-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 |
+ Plus or Pi 2) |
+ N.B. For Pi3 see pi3-act-led overlay. |
+ |
+ 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. |

+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. |
