[PATCH v2 1/3] dt-bindings: vendor-prefixes: Add Beijing Ultrapower Software Co., Ltd.

[Jun Yan]

Beijing Ultrapower Software Co., Ltd. is a company focusing on global
mobile games, ICT services, cloud computing, and artificial intelligence
solutions.

TaiqiCat A01 is a blockchain-based terminal product launched by UQSoft
(Beijing UQSoft Interactive Technology Co., Ltd.), a wholly-owned
subsidiary of Ultrapower. Its dedicated product homepage[1] was once
hosted on Ultrapower’s official website[2].

It should be noted that UQSoft's official website[3] is no longer
operational, and the company appears to have been discontinued.

[PATCH v2 3/3] arm64: dts: allwinner: h6: Add TaiqiCat (TQC) A01 support

[Jun Yan]

TaiqiCat (TQC) A01 is a set-top box powered by an Allwinner H6 SoC,
equipped with an AXP305 PMIC, 1GB LPDDR3 RAM, 8GB eMMC, an AP6212
WiFi/BT combo module, one 100M Ethernet port, one USB 3.0 Type-A port,
one USB 2.0 Type-A port, one Micro USB port, HDMI, SPDIF, Micro-SD, and
infrared input.

It was released by Ultrapower(UQSoft) as a blockchain-based terminal and is
now discontinued and no longer supported.

  https://web.archive.org/web/20190409213228/https://tq.ultrapower.com.cn/product.html

Hardware schematics are not available at this time; however, the
dts from the vendor firmware is provided for reference [1].

Based on the PCB silkscreen marking "AZW-KT02 2.0", the ODM/OEM
can be confirmed as AZW, and the overall hardware circuit design
is highly similar to the Beelink GS1.

Tested, works:
- debug UART
- status LED
- USB 3.0 Type-A port
- USB 2.0 Type-A port
- Micro USB port (Host)
- MicroSD
- eMMC
- WiFi/Bluetooth
- HDMI video output

Does not work:
- Ethernet (requires AC200 MFD/EPHY driver)
- HDMI audio

Untested:
- SPDIF
- IR receiver

Many thanks for sending this upstream, this looks very good overall,

I don't think we need the serial1 alias? Bluetooth should work even
without knowing the ttyS<x> device name, shouldn't it?

But you should add an alias for the WiFi (ethernet0 = &brcm;), so that
U-Boot assigns an ideally unique MAC address.

The rest looks correct, from a pure upstream DT perspective, and by
comparing it to other H6 .dts files, even though I cannot test it, of
course. But I trust you that those things you mentioned work.

So with the aliases changed:

Thank you for the review. 

I will implement the changes you suggested in PATCH v3:
1. drop the serial1 alias
2. add an ethernet0 alias for WiFi.

My apologies for not including the Changes section.

Changes in v2:                                                                                                                                                                         
- Replace "UQSoft" with "Ultrapower", and add relevant explanations.
- Link to v1: https://lore.kernel.org/all/20260226084850.417731-1-jerrysteve1101@gmail.com
