[PATCH 0/2] riscv: dts: spacemit: Add initial support for MusePi Pro

[Troy Mitchell]

This patchset adds initial device tree support for the MusePi Pro board.

Muse Pi Pro [1] is a single-board computer integrating a high-performance
RISC-V 8-core processor, storage, I/O and expansion capabilities into
a credit card-sized 1.8-inch board.

you could wrap at slightly more characters, I remember 72 chars
(haven't spent time to find a formal document link..)

I'd suggest to list core features of this board, while using this link as a complement,
base on previous experience, vendor may change the link address, thus the link vanish

The link doesn't even work for me. Is this board actually made by
spacemit as a developer platform?

Could you double check if it really doesn't work now?

Yes.

With the link, that seems pretty clear. Not sure why the link didn't
work before, but it is working now.

[PATCH 2/2] riscv: dts: spacemit: Add MusePi Pro board device tree

[Troy Mitchell]

From: Troy Mitchell <troy.mitchell@linux.spacemit.com>

Add initial device tree support for the MusePi Pro board [1].
The board is using the SpacemiT K1/M1 SoC.

The device tree is adapted from the SpacemiT vendor tree [2].

This minimal device tree enables booting into a serial console with UART
output and a blinking LED.

this is a little bit short, how about make it "SpacemiT MusePi Pro"?

swap these two lines, for similar reason, see my comment here

while you are here, I'd suggest to push as many features as possible
instead of this minimal DT, which say - PMU, emmc, ethernet should be ready..
(ethernet is in next, should show up at v6.18-rc1)

Good idea.
I think I should split these into multiple commits, right?
Like, PDMA and EMAC should definitely be two separate commits.
