[PATCH 0/3] dts: arm64: sunxi: add initial support for t95 tv box

[Kamil Kasperski]

T95 is a most commonly known for being a box with a pre-installed malware.
It uses Allwinner H616 and comes with eMMC and DDR3 memory.
This device comes with two versions - one with AXP305 PMIC and another with AXP313 PMIC.

[PATCH 1/3] dt-bindings: vendor-prefixes: sunxi: add T95 string

[Kamil Kasperski]

T95 is a commonly known as series of cheap chinese TV Boxes with unknown brand.
Since their Android OS is built from Google Pixel 2 sources, all footprints metadata contain Google strings.
Let's assume the vendor of these boxes is t95.

Please use scripts/get_maintainers.pl to get a list of necessary people
and lists to CC. It might happen, that command when run on an older
kernel, gives you outdated entries. Therefore please be sure you base
your patches on recent Linux kernel.

Tools like b4 or scripts/get_maintainer.pl provide you proper list of
people, so fix your workflow. Tools might also fail if you work on some
ancient tree (don't, instead use mainline), work on fork of kernel
(don't, instead use mainline) or you ignore some maintainers (really
don't). Just use b4 and everything should be fine, although remember
about `b4 prep --auto-to-cc` if you added new patches to the patchset.

You missed at least devicetree list (maybe more), so this won't be
tested by automated tooling. Performing review on untested code might be
a waste of time, thus I will skip this patch entirely till you follow
the process allowing the patch to be tested.

Please kindly resend and include all necessary To/Cc entries.


Best regards,
Krzysztof

[PATCH 3/3] dts: arm64: sunxi: add initial dts for T95 AXP313 tv box

[Kamil Kasperski]

T95 is a most commonly known for being a box with a pre-installed malware.
It uses Allwinner H616 and comes with eMMC and DDR3 memory.

Those TV boxes usually come with common hardware:
- Allwinner H616 SoC
- 2/4 GB DDR3 SDRAM (Hynix H5TQ2G43BFR)
- 16/32/64 GB eMMC
- microSD slot
- AXP305 or AXP313 PMIC depending on board revision
- 3.5mm A/V output
- HDMI port
- 2x USB 2.0 ports
- 100M ETH using Internal PHY
- 7-segment display
- DC 5V barrel jack port

The board contains holes hor UART header wired to &uart0.
From the DRAM specification its operation voltage is 1.5V.

Please use subject prefixes matching the subsystem. You can get them for

I have this board and it always felt like a clone of X96 Mate, which is
already supported in kernel, except for broken sd card detection. Would it
make sense to unify those two boards and just overwrite or update parts here
that are not the same?

I think the box you have is an older one, with the AXP305? IIUC, this is
about a newer revision with the AXP313. There are quite some differences
between the two PMICs, though it might still make sense to share the DTs,
see the OrangePi Zero[23].

Andre

Right, mine is with AXP305. It has "T95MAX v4.0" printed on PCB.

Kamil, does your board also have "MAX" mentioned somewhere?

Re: [PATCH 0/3] dts: arm64: sunxi: add initial support for t95 tv box

[Kamil Kasperski]

Hi Jernej, Andre!

Thanks for the reply. My board has a name "H616-T95MAX-AXP313A-v3.0".

I believe these boards are two different revisions and the one with 
AXP313A is a newer one, besides incorrectly label as v3.0. Sharing 
common configuration between boxes is also a good idea but for this 
specific configuration I would be cautious. From my experience with this 
board the default configuration for X96 Mate is not working at all. I 
suspect because of the PMIC and DRAM differences.

Memory installed in X96 Mate is DDR3L and in mine T95 it's DDR3, hynix 
H5TQ2G43BFR, that requires 1.5V to operate.

The rest of configuration for both boards, like HDMI, MMC, EPHY and 
audio codec seems to be the same across almost all H616-based boxes that 
I've researched.


Moreover please let me update the patches and send v2 that aligns with 
mainline branch. I've incorrectly assumed to use sunxi fork instead of 
master. Sorry!

Re: [PATCH 0/3] dts: arm64: sunxi: add initial support for t95 tv box

[Kamil Kasperski]

Hi Jernej, Andre!

Thanks for the reply. My board has a name "H616-T95MAX-AXP313A-v3.0".

I believe these boards are two different revisions and the one with 
AXP313A is a newer one, besides incorrectly label as v3.0. Sharing 
common configuration between boxes is also a good idea but for this 
specific configuration I would be cautious. From my experience with this 
board the default configuration for X96 Mate is not working at all. I 
suspect because of the PMIC and DRAM differences.

Memory installed in X96 Mate is DDR3L and in mine T95 it's DDR3, hynix 
H5TQ2G43BFR, that requires 1.5V to operate.

The rest of configuration for both boards, like HDMI, MMC, EPHY and 
audio codec seems to be the same across almost all H616-based boxes that 
I've researched.


Moreover please let me update the patches and send v2 that aligns with 
mainline branch. I've incorrectly assumed to use sunxi fork instead of 
master. Sorry!

Ok, we for sure need to integrate this somehow to compatible string, since
there are at least two incompatible versions.

PMIC is important difference, yes, but not DRAM. DDR3L is completely compatible
with DDR3. It just additionally supports lower voltages. Additionally, Linux
doesn't care about DRAM type and all. It's firmware responsibility to properly
initialize it.

It's good idea to introduce dtsi with common configuration for both boxes and add 2 new dts files with compatible string
"t95,t95max-axp313" and "t95,t95max-axp305" with separate PMIC configuration. Similarly as OrangePI Zero got handled.

Not to mention, that it looks like arch/arm64/boot/dts/allwinner/sun50i-h618-transpeed-8k618-t.dts also has very similar configuration to my T95 box. Question is should we mix up the compatible strings for SoC?
I know that H616 and H618 are almost identical SoCs, but if it's not only a matter of documentation it's still better idea to push new dts.

Kamil

Not sure what do you mean. We can mix and match whatever DTSI we want. However,
board compatible reflect SoC in them. So yes, if it make sense, Transpeed 8k618-t
can share same common DTSI, just board level DTS will have H616 compatible.

And line length should be 78 character max. Please read Linux netiquette.

Correct.

Not sure what do you mean. We can mix and match whatever DTSI we want. However,
board compatible reflect SoC in them. So yes, if it make sense, Transpeed 8k618-t
can share same common DTSI, just board level DTS will have H616 compatible.
