The three components are separated into +two sub-images or planes. The Y plane has one byte per pixel and pixels +are grouped into 128 byte wide columns.

If there is any +paddding, then that will be reflected via the selection API. +The luma height must be a multiple of 2 lines. + +The normal bytesperline is effectively fixed at 128.

@@ +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.
