-From: notro <notro@tronnes.org>
-Date: Wed, 9 Jul 2014 14:46:08 +0200
-Subject: [PATCH 025/222] BCM2708: Add core Device Tree support
-
-Add the bare minimum needed to boot BCM2708 from a Device Tree.
-
-Signed-off-by: Noralf Tronnes <notro@tronnes.org>
-
-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.

-+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
-+===================================
-+
-+Name: <The base DTB>
-+Info: Configures the base Raspberry Pi hardware
-+Load: <loaded automatically>
-+Params:
-+ audio Set to "on" to disable 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 "off")
-+
-+ uart0 Set to "off" to disable uart0 (default "on")
-+
-+ 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")
-+
-+ 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)
-+
-+ 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.
