The BeagleV Ahead single board computer [1] features the T-Head TH1520
SoC. Similar to the Lichee Pi 4A series from Jisheng [2], this adds a
minimal device tree file to support booting to a basic shell [3].
Changes since v2:
- Drop the MAINTAINERS patch as it is not important and I want this
patch series to make it into the next PR
- Add Conor's R-b
Changes since v1:
- Add dual license to dts file as Conor noted this is typical
- Reorder new entry in thead.yaml to maintain alphabetical order per
suggestion by Krzysztof
- Add A-b's and R-b's from v1

The BeagleV Ahead single board computer uses the T-Head TH1520 SoC.
Add a minimal device tree to support basic uart/gpio/dmac drivers so
that a user can boot to a basic shell.

Am I supposed to take this, or will you? I still don't know where I
stand with any of this and will default to assuming things are for me
to take in the absence of clarity.
Thanks,
Conor.

Okay, I will go grab both.
Can you please decide if you want me to take the patches going forward,
or will make a git tree, put it in linux-next & send PRs to the SoC
maintainers? One or the other, not this ad-hoc mix where neither I nor
contributors know?
Thanks,
Conor.

Hi Conor,
Since the patches in this window is small, so yes please help us to
take this series and the one of changing the dts license. I see Guo Ren
has acked it, I will ack too soon.
