This patch series adds very basic support for Allwinner A83T SOC.
Clock, peripherals, smp support will be added later.
Allwinner A83T is octa-core cortex-a7 based SoC.
It's clock control unit and prcm, pinmux are different from previous sun8i
series.
Its processor cores are arragned in two clusters 4 cores each,
similar to A80.
Note: A83T pincontroller patch is already applied by Linus, so not added in this
patch.
changes from v2->v3
1. removed "Not Supported" for A83T in sunxi/README
2. removed un-unsed nodes from dtsi.
3. corrected GIC_SPI number for PH_EINT in dtsi.
4. removed address at soc node which was un-necessary.
5. corrected reg<> addresses for cpu nodes.
6. changed cpu mask to 8 in gic and archtimer node.
changes from v1->v2:
1. used UART0 header with PB9, PB10 pins.
2. removed unnecessary includes and comments from dtsi.
3. arranged nodes in alphabatical order.
4. arrnaged compatible in alphabatical order.
5. changed cpu nodes to use cpu@100 -cpu@-103.
6. changed dts filename.

1.9.1
H8Homlet Proto v2.0 Board is A83T Dev Board by Allwinner.
It has UART, ethernet, USB, HDMI, etc ports on it.
A83T patches are tested on this board.
It has UART, ethernet, USB, HDMI, etc ports on it.
For FEL mode it needs USB A-A(Male) cable. I used uart0 which
is multiplexed to microsd pins PF2 and PF4.
Enabled UART0 Header(PB9, PB10 pins).

I did not get what you are trying to say here, could you please elaborate?
I'll correct mistakes, and re-send this patch, is it okie?

I've received my Onda 989 Air based on A83T, I do not find another
UART on it, rather I did not spend enough time to find.
These nodes will help me adding nodes locally everytime I use Onda Air
using microSD Breakout Board, I request to keep those.

In your first patch, you add a CLK_OF_DECLARE for the H3 compatible in
clk-sunxi.c
Judging from your clocks node above, you don't need it at all.
I'm guessing you'll need it later on, but I wanted to know if that was
intentional :)
