Rafał Miłecki 313197d707 brcm2708: backport upstream ARM dts commits 
This gets us in sync with dts from kernel 4.11. Two patches were already
backported earlier.
I decided to use 03x prefix as it's kind of similar to the 3xx prefix:
3xx - architecture specific patches
It isn't any documented or strict rule though. We don't need to stick to
it if we hit any problems.

Subject: [PATCH] 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.

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.

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

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.

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.

BCM270X_DT: Add a .dtbo target, use for overlays
Change the filenames and extensions to keep the pre-DDT style of
overlay (<name>-overlay.dtb) distinct from new ones that use a
different style of local fixups (<name>.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.

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.

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.

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.

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

+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.dtbo 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. When editing this file, please preserve the indentation levels to make it
+simple to parse programmatically. NO HARD TABS.
+
+
+Name: <The base DTB>
+Info: Configures the base Raspberry Pi hardware
+Load: <loaded automatically>
+Params:
+ audio Set to "on" to enable 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 "on")
+
+ sd_overclock Clock (in MHz) to use when the MMC framework
+ requests 50MHz
+
+ sd_force_pio Disable DMA support for SD driver (default off)
+
+ sd_pio_limit Number of blocks above which to use DMA for
+ SD card (default 1)
+
+ sd_debug Enable debug output from SD driver (default off)
+
+ uart0 Set to "off" to disable uart0 (default "on")
+
+ uart1 Set to "on" or "off" to enable or disable uart1
+ (default varies)
+
+ 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")
+ N.B. For Pi3 see pi3-act-led overlay.
+
+ 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)
+ N.B. For Pi3 see pi3-act-led overlay.
+
+ 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.
+
+Further reading

+
+This is only meant to be a quick introduction to the subject of Device Tree on
+Raspberry Pi. There is a more complete explanation here:
