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 ---- - arch/arm/boot/dts/Makefile | 30 + - arch/arm/boot/dts/bcm2708-rpi-b-plus.dts | 145 +++++ -

b/arch/arm/boot/dts/overlays/README -@@ -0,0 +1,648 @@ -+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-overlay.dtb 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.
