[PATCH v3 0/5] ARM: dt: sunxi: Add Itead Ibox support

[codekipper-Re5JQEeQqe8AvxtiuMwx3w]

From: Marcus Cooper <codekipper-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Hi All,

this patch series is an extension of the initial patch delivery for the
Itead Ibox as found here
https://groups.google.com/d/msg/linux-sunxi/GR_co3ObW8s/0BTPQljmAAAJ.

There seems to be a few Itead variants out there based on their A10/A20
core module and this patch series attempts to organise the device tree
files with some consideration that these variants may be added later.

I've also converted the A10 Itead Iteaduino dts to use these common files.
As I don't have this board to verify the changes I simply compared the
output of the fdtdump before and after applying these patches. The only
difference was the addition of codec support and a reduction to the dcdc2
max voltage.

BR,
CK

---
Changes since v2:
- removed duplicate naming
- moved enabling of some peripherals to board level.

Changes since v1:
- Added audio codec.
- Seperated into individual patches
- added Itead A10 core dtsi
- modified sun4i-a10-itead-iteaduino-plus.dts to use itead common core dtsi

[PATCH v3 1/5] ARM: dts: sunxi: Add sunxi-itead-core-common.dtsi

[codekipper-Re5JQEeQqe8AvxtiuMwx3w]

From: Marcus Cooper <codekipper-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

Itead have a core module board that can be populated with either
an Allwinner A10 or A20 SoC. This patch creates a common dtsi
which these boards can use.

[PATCH v3 3/5] ARM: dts: sun7i: Add Itead Ibox support

[codekipper-Re5JQEeQqe8AvxtiuMwx3w]

From: Marcus Cooper <codekipper-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

The Itead Ibox is a multi board device based on the Allwinner A20 SoC.
It contains the A20 Itead Core module and a base board for the external
interfaces.

The core module comes with 4GB NAND and 1GB DDR RAM.

The base board to which the core board is connected provides 3 USB 2.0 Host
ports, 1 USB 2.0 OTG, 1 uSD slot, 10/100 Ethernet port, HDMI, IR receiver,
SPDIF and a 32-pin GPIO header. This header expands the features of core
board by exposing the VGA pins, audio In/Out pins, SATA, SPI, I2C, UARTS,
USB-OTG and power.
