[PATCH v4 0/3] Add basic support for Allwinner A83T SOC

[PATCH v4 0/3] Add basic support for Allwinner A83T SOC

[Vishnu Patekar]

Hello,

Re-sending after corrections, I've some more patches on top of this will send
them separately to avoid delaying this one with new comments.

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 v3->v4
1. arranged sub nodes in soc as per address.
2. removed memory node.
3. corrected style problem in dtsi.

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.

[PATCH v4 2/3] ARM: dts: sun8i: Add Allwinner A83T dtsi

[Vishnu Patekar]

Allwinner A83T is new octa-core cortex-a7 SOC.
This adds the basic dtsi, the clocks differs from
earlier sun8i SOCs.

Just put the clocks under the root node. 'clocks' is not a special node.

No, it's not a special node, but it's a very convenient one. It avoids
"crippling" the main SoC definition with all the clocks definition,
and keep the noise relatively low.

And a bunch of other maintainers seem to agree:
$ git grep "clocks {"  -- arch/arm/boot/dts/ arch/arm64/boot/dts/ | wc -l

[PATCH v4 3/3] ARM: dts: sun8i: Add A83T HomletV2 Board by Allwinner

[Vishnu Patekar]

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).
