[PATCH 0/2] Add support for Xiaomi Mi TV Stick

[PATCH 0/2] Add support for Xiaomi Mi TV Stick

[Ferass El Hafidi]

From: Ferass El Hafidi <funderscore@postmarketos.org>

This patch series aims to add initial support for the Xiaomi Mi TV
Stick.

Xiaomi Mi TV Stick is a small Amlogic-based Android TV stick released in 
2020, and known as `xiaomi-aquaman` internally (in the downstream kernel,
u-boot, ...)
Its specifications are as follows:
 * Amlogic S805Y SoC (believed to be mostly identical to S805X)
 * 8 GB eMMC
 * 1 GB of RAM
 * Android TV 9, upgradable to Android TV 10

There are multiple variants:
 * 1. Green PCB, manufactured in 2020, known UART pinout (helpfully 
   labeled on the board)
 * 2. Blue PCB, not much documentation about it, presumably manufactured
   between 2021 and 2023
 * 3. Green PCB, manufactured in 2023, known UART pinout, some layout
   changes compared to the 2020 variant

Among these variants, there are many boards using multiple different
Wi-Fi chips.  Supporting all of them is out of scope for this patch
series.

As of the time of writing this has only been tested on the 3rd variant.
It is believed that software-wise all three work mostly the same (if we 
don't count Wi-Fi), but testing on the other variants would still be
appreciated.

The devicetree is based on the Amlogic P241 DTS.

If this is S805Y not S805X, you should add a new binding section for
S805Y devices, and add the board there.

e.g. I did this for S905L (GXLX) devices:

If this was cloned from the p241 file I would retain the Baylibre

Amlogic Y variants normally omit CVBS, Ethernet, SD, and sometimes IR,
so you could clone the s805x.dtsi and remove nodes there, then include
an s805y.dtsi file. Perhaps not worth the effort for a single device
at this time, but could be done as future optimisation.

After updating the bindings, use “amlogic,s805y” here.

I’d use “Xiaomi Mi TV Stick (Aquaman)” so the connection between the
binding name and model name is obvious.

If you add a generic SDIO node here board variants will have working
WiFi regardless of the module used. The idea is used here:

I could do it in v2.  Could be worth the effort long-term.

I added "(S805Y)" to differenciate from the other, much newer stick also 
known as an "Xiaomi Mi TV Stick", which uses a completely different Amlogic 
SoC and has different specs, though from what I can tell most commonly call 
that completely different stick, a "Xiaomi Mi TV Stick 4K".

I wanted to retain the vendor name, and since there is a 15 char limit,
just to be safe I used `MI` instead of `XIAOMI`. But I guess 
"XIAOMI-AQUAMAN" should be fine after all.

But not all modules are supported in mainline at the moment, that's what I 
meant by "out of scope for this patchset".

Re: [PATCH 2/2] arm64: dts: amlogic: add support for xiaomi-aquaman/Mi TV Stick

[Martin Blumenstingl]

Hello,

thanks for the patch - I have a few small comments below.

You're inheriting  "meson-gxl-s805x.dtsi" but I can't see that this -
or its parents - define a cvbs-connector node anywhere.
Can we just omit it completely

nit-pick: since you're planning to send a v2 anyways, keep it at one
blank line here

Similar to the cvbs-connector: status = "disabled" should be the default here

why are there Ethernet LED pins if there's no Ethernet connector?

This is also disabled by default

Please drop clocks and clock-names to make this work with linux-next.
Background: [0] is queued for the next release and it means that the
PWM controller driver will now pick the "best" clock on it's own and
overriding here will likely result in your board not booting.

I'm guilty of this myself and I think you can be better here:
Use vbus-supply = <&vcc_5v>; in the &usb node to correctly describe
where the USB VBUS signal is coming from.
(I believe that the PHY is not internally powered by 5V as the SoC
doesn't take any 5V inputs)


Best regards,
Martin

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y for arch/arm64/boot/dts/amlogic/' for 20250131200319.19996-1-funderscore@postmarketos.org:

I don't think I touched that bit.

I'll fix the rest in a v2, thanks!
