T7 is an advanced application processor designed for smart display.
Add the new T7 SoC/board device tree bindings.
Add basic support for the T7 based Amlogic AN400 board, which describes
the following components: CPU, GIC, IRQ, Timer, UART. It's capable of
booting up into the serial console.

Lucas has already sent patches for the T7 SoC & is at v5:
https://lore.kernel.org/linux-devicetree/[email protected]/
There's been a bit of discussion there, and there serial stuff in
particular is different in his series (it doesn't use always-on for
examples).
Could you please go and take a look at his series?
Cheers,
Conor.

AN400 is the reference board designed by Amlogic, which is different
from Khadas VIM4.
And T7 serial is the same as S4, so I follow S4 serial.

Yet you share the same dtsi, which he has got through several iterations
of before you arrived.

Yeah, no. SoC specific compatible please.

Please coordinate with Lucas so a single bindings & dtsi patches are submitted,
in any case only a single one will be reviewed and merged.
You can rebase your AN400 dts on top of his VIM4 initial patchset.
Thanks,
Neil

Hi Lucas,
Are you going to continue with the dtsi part?

Hi Xianwei,
I am doing the basics for Amlogic T7 A311D2, but the next step ( sd
card or emmc, something to boot on) would be more difficult for me
than you.
After the first series for Vim4 gets merged, I will start to work on
how to get sd cards working.
But if you already have that working for the AN400 board, please send
it. And I will look at that work and use it for Vim4.
Or, if you don't have it ready and want to share it with me, we can
work together on these A311D2 patches.
You test on AN400, and I test on Vim4.
Thanks
Lucas

We are preparing this part. However it depends on clock. So the clock
must ready first.

Will you send clock for T7?
