From d060fc0b45684ad90d12d81e08680f03fc44e305 Mon Sep 17 00:00:00 2001 From: notro Date: Wed, 9 Jul 2014 14:46:08 +0200 Subject: [PATCH 0040/1085] 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 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 notro@tronnes.org 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 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. Signed-off-by: Matthias Reichl SDIO-overlay: add poll_once-boolean parameter Add paramter to toggle sdio-device-polling done every second or once at boot-time. Signed-off-by: Patrick Boettcher 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.

Signed-off-by: Noralf Trønnes BCM270X_DT: Add a .dtbo target, use for overlays Change the filenames and extensions to keep the pre-DDT style of overlay (-overlay.dtb) distinct from new ones that use a different style of local fixups (.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. Signed-off-by: Phil Elwell 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. Signed-off-by: Phil Elwell 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 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 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 Signed-off-by: Herve Jourdain Signed-off-by: Khem Raj BCM270X: Drop position requirement for CMA in VC4 overlay. No longer necessary since 2aefcd576195a739a7a256099571c9c4a401005f, 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. + +The Overlay and Parameter Reference +=================================== + +N.B.
