[PATCH v5 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/2023/8/2/801
"dt-bindings: mfd: x-powers,axp152: make interrupt optional for more chips".

Due to the threading issues v5 is sent via my SoMainline email.

Cheers,
Martin
