Thank you for the PR! I haven't had a chance to look at the schematics yet but can some of these be added to the devicetree? I understand some --but hopefully not all-- of these peripherals are powered through the unsupported (yet!) AXP2101 PMIC's regulators, but it might still make sense to already describe them in the DT.

Yeah, I will try to add some other peripherals to the DT (and will also try to make them work if I can) . A friend of mime will take a look at AXP2101 regulator & AW9532B LED/GPIO controller(also unsupported yet) driver support later days once he has time.

I am also working on supporting CoreS3 with #79765 based on this.
There are some areas that need improvement, so please consider fixing them.

@soburi I had got backlight working， but display still need some work to be done.

And also need to fix CI errors.

In Zephyr, when committing to minimal support, it is often submitted with Hello World and blinky working, that is, GPIO and UART working. My PR #79765 and #78098 are also related, so it's better to proceed with the already finished part.

Yes, agree. The very first commit has hello world working. (but blinky seems rely on the external GPIO controller-aw9523b, there is also a test/wip version implementation https://github.com/zhxt/zephyr/tree/main-gpio-aw9523b),

It's very busy on daily work recently, haven't got much time working on this porting, -_-

My PR #79765 contains AXP2101 LED contrl feature support.
So, I think the request to run blinky sample can be aside temporary.
(It not run the real blinky sample, but the same functionality work.)
I think it is good to finish this PR with minimam functionality.

Yeah, will try to get more time to finish a minimal version.
