From: Martin Botka <[email protected]>
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 (USB-OTG doesnt work)
- 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.

Changes in V2:
- Fixed whitespace errors
- Move UART into carrier boards and BTT Pi
- Remove usb1-vbus regulator
- Fix ranges and naming of AXP313A rails
- Add comment specifying why broken-cd in mmc0 is needed
- Rename sdio_wifi to wifi
- Specify in commit description that USB-OTG doesnt work

This must follow what you just added to sunxi.yaml, so:
"bigtreetech,cb1-manta", "bigtreetech,cb1", "allwinner,sun50i-h616";
And you need the human readable "model" string *here*.

Extra empty line here.

Apart from the missing semicolon, which actually breaks the build (as you
have discovered yourself): there shouldn't be a model string in a .dtsi
file, that should be confined to the final board .dts, just as a human
readable form of the board compatible string. So drop this here, and add
the respective name to the two .dts files.
Rest looks fine now, thanks.
Cheers,
Andre
