2d0c3d6b16 sunxi: DT: H3: update board .dts files from Linux
Update the .dts file for the various boards with an Allwinner H3 SoC.
This is as of v4.18-rc3, exactly Linux commit:
commit 721afaa2aeb860067decdddadc84ed16f42f2048 (HEAD)
Merge: 7c00e8ae041b 87815dda5593
Author: Linus Torvalds <torvalds@linux-foundation.org>
Date:   Mon Jun 11 17:57:38 2018 -0700

    Merge tag 'armsoc-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

This also includes the OrangePi Zero .dts, which technically has an
Allwinner H2+ SoC.

d7b17f1c24 sunxi: Split out common board design for ALL-H3-CC device tree
The Libre Computer Project ALL-H3-CC has three models, all using the
same board design, but with different pin compatible SoCs and amount of
DRAM.

Currently only the H3 1GB DRAM variant is supported. To support the two
other variants, first split the original device tree into a common board
design part and an SoC specific part.

The SoC part only defines which SoC is used and model name, and includes
the SoC specific dtsi file and the common design dtsi file.

Also fix up the SPDX identifier line to use the correct comment style,
and place it on the first line.

e88d2a57f3 arm: dts: sunxi: update H3 to new EMAC binding
The U-Boot driver for the sun8i-emac was using some preliminary DT
binding. Now since Linux got its own driver in v4.15 and our driver
can now cope with both bindings, let's convert the DT nodes used by the
various H3 boards over to the new bindings used by the kernel.

afe2754412 sunxi: Add support for Libre Computer Board ALL-H3-CC H3 ver.
The Libre Computer Board ALL-H3-CC from Libre Technology is a Raspberry
Pi B+ form factor single board computer based on the Allwinner H3 SoC.
The board has 1GB DDR3 SDRAM, provided by 4 2Gb chips. The mounting holes
and connectors are in the exact same position as on the Raspberry Pi B+.

Raspberry Pi B+ like peripherals supported on this board include:

  - Power input through micro-USB connector (without USB OTG)
  - Native 100 Mbps ethernet using the internal PHY, as opposed to
    USB-based on the RPi
  - 4x USB 2.0 host ports, directly connected to the SoC, as opposed to
    being connected through a USB 2.0 hub on the RPi
  - TV and audio output on a 3.5mm TRRS jack
  - HDMI output
  - Micro-SD card slot
  - Standard RPi B+ GPIO header, with the standard peripherals routed to
    the same pins.

    * 5V, 3.3V power, and ground
    * I2C0 on the H3 is routed to I2C1 pins on the RPi header
    * I2C1 on the H3 is routed to I2C0 pins on the RPi header
    * UART1 on the H3 is routed to UART0 pins on the RPi header
    * SPI0 on the H3 is routed to SPI0 pins on the RPi header,
      with GPIO pin PA17 replacing the missing Chip Select 1
    * I2S1 on the H3 is routed to PCM pins on the RPi header

  - Additional peripherals from the H3 are available on different pins.
    These include I2S0, JTAG, PWM1, SPDIF, SPI1, and UART3

In addition, there are a number of new features:

  - Console UART header
  - Consumer IR receiver
  - Camera interface (not compatible with RPi)
  - Onboard microphone
  - eMMC expansion module port
  - Heatsink mounting holes

This patch adds defconfig and dts files for this board. The dts file is
the same as the one submitted for inclusion in Linux, with some minor
revisions to match the dtsi file and old EMAC bindings in U-boot.

Since the OTG controller is wired to a USB host port, and the H3 has
proper USB hosts to handle host mode, the MUSB driver is not enabled.
