BCM2708: Add core Device Tree support

Browse Source 
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: Use raspberrypi-power to turn on USB power

Use the raspberrypi-power driver to turn on USB power.

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

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

BCM270X: Drop position requirement for CMA in VC4 overlay.

No longer necessary since 2aefcd576195a739a7a256099571c9c4a401005f,

allocation (particularly on pi0/1).

/* Pi3 uses a GPIO expander to drive the LEDs which can only be accessed
from the VPU. There is a special driver for this with a separate DT node,
which has the unfortunate consequence of breaking the act_led_gpio and
act_led_activelow dtparams.
This overlay changes the GPIO controller back to the standard one and
restores the dtparams.

/*
* Definitions for Allo Piano DAC (2.0/2.1) boards
*
* NB. The Piano DAC 2.1 board contains 2x TI PCM5142 DAC's. One DAC is stereo
* (left/right) and the other provides a subwoofer output, using DSP on the
* chip for digital high/low pass crossover.
* The initial support for this hardware, that doesn't require any codec driver
* modifications, uses only one DAC chip for stereo (left/right) output, the
* chip with 0x4c slave address. The other chip at 0x4d is currently ignored!
