[PATCH v6 0/4] Add BigTreeTech CB1 SoM & Boards

[PATCH v6 0/4] Add BigTreeTech CB1 SoM & Boards

[Martin Botka]

Hello,
This series adds a vendor prefix for BigTreeTech and adds BigTreeTech CB1,
Manta board and BigTreeTech Pi.

CB1 is just an SoM thats based on AllWinner H616.
BigTreeTech Manta boards are expander boards for CB1 and BigTreeTech Pi
is an CB1 in Rpi style with few additional things like IR receiver and fan port
on GPIO.

This work started before I was hired by BigTreeTech and thus majority of the
patches are from SoMainline email and few are from my work email.

This series depends on commit https://lkml.org/lkml/2023/8/28/1073
and https://lkml.org/lkml/2023/8/2/801

Cheers,
Martin

Changes in v6:
- Remove SPI node from BTT Pi (To be used via overlays)
- Rebase on top of 6.6-rc1

Changes in v5:
- Removal of wifi node comments that were obvious from properties

Changes in v4:
- Extend the range of vcc-dram to 1.5V (Max of 1.35V caused issues with booting up)

Changes in v3:
- Add missed semicolons
- Move model string from dtsi to board dts
- Add cb1 compatible to manta
- Remove extra empty lines
- Add pinctrl for SPI0

Changes in v2:
- Fix alphabetical order in vendor prefixes
- Remove CB1 SoM from bindings (Its not standalone)
- Fixed whitespace errors
- Move UART into carrier boards and BTT Pi
- Remove usb1-vbus regulator
- Fix ranges and naming of AXP313A rails
- Add comment why broken-cb in mmc0 is needed
- Rename sdio_wifi to wifi
- Add model string to BTT Pi
- Enable IR receiver for BTT Pi

[PATCH v6 3/4] arm64: dts: allwinner: h616: Add BigTreeTech CB1 SoM & boards support

[Martin Botka]

CB1 is Compute Module style board that plugs into Rpi board style adapter or
Manta 3D printer boards (M4P/M8P).

The SoM features:
  - H616 SoC
  - 1GiB of RAM
  - AXP313A PMIC
  - RTL8189FTV WiFi

Boards feature:
  - 4x USB via USB2 hub (usb1 on SoM).
  - SDcard slot for loading images.
  - Ethernet port wired to the internal PHY. (100M)
  - 2x HDMI 2.0. (Only 1 usable on CB1)
  - Power and Status LEDs. (Only Status LED usable on CB1)
  - 40 pin GPIO header

Currently working:
  - Booting
  - USB
  - UART
  - MMC
  - Status LED
  - WiFi (RTL8189FS via out of tree driver)

I didnt want to duplicate things so the manta DTS can also be used on BTT pi4b adapter.
CB1 SoM has its own DTSI file in case other boards shows up that accept this SoM.

[PATCH v6 4/4] arm64: dts: allwinner: h616: Add BigTreeTech Pi support

[Martin Botka]

From: Martin Botka <martin@biqu3d.com>

The BigTreeTech Pi is an H616 based board based on CB1.
Just in Rpi format board.

It features the same internals as BTT CB1 but adds:
    - Fan port
    - IR receiver
    - ADXL345 Accelerometer connector via SPI
    - 24V DC power supply via terminal plugs
    - USB to CAN module connector (External Module)

List of currently working things is same as BTT CB1 but also:
    - IR receiver
    - ADXL345 connector
