b/arch/arm/boot/dts/overlays/README +@@ -0,0 +1,3040 @@ ++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. ++ ++The Overlay and Parameter Reference ++=================================== ++ ++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.

The same board-specific mapping applies to i2c_baudrate, ++ and the other i2c baudrate parameters. ++ ++ ++Name: act-led ++Info: Pi 3B, 3B+, 3A+ and 4B use a GPIO expander to drive the LEDs which can ++ only be accessed from the VPU.
