Hi Hal,

I just want to double check, is "VisionFive 2 VA" / "visoinfive-2-va"
and "VisionFive 2 VB" / "visionfive-2-vb" really what you want? I
still think having these names match what is printed on the silkscreen
makes it a lot easier for everybody. Even your own releases calls the
boards "v1.2A" and "v1.3B":
https://github.com/starfive-tech/VisionFive2/releases/

So I'd suggest
model = "StarFive VisionFive 2 v1.3B";
compatible = "starfive,visionfive-2-v1.3b", "starfive,jh7110";

I haven't seen these "VA" and "VB" anywhere else, so if you don't want
the version numbers and can promise that there will be no incompatible
future revisions of the boards then maybe just drop the "V". Eg.
model = "StarFive VisionFive 2 B";
compatible = "starfive,visionfive-2-b", "starfive,jh7110";

The version A board has reached the end of life. As far as I know, the
version B board will not update also unless there are some important
requirements and StarFive decides to update. Furthermore, it's too late
to change the compatible as patch 1 was already accepted. Will it be
easier to read if I modify it as below?

	model = "StarFive VisionFive 2 vB";
	compatible = "starfive,visionfive-2-vb", "starfive,jh7110";

Best regards,
Hal

Oh, that's sad that the kernel will now end up calling the boards
something that's used nowhere else, even by StarFive :/
But yeah, I guess vA and vB are a little easier to read.

Nothing has been released with that name so AFAIU we can change it
still. If you sort it out today/tomorrow I'll try get it to Arnd before
the merge window opens...

I might've jumped the gun a bit here, I thought that it'd been changed
to what you (Emil) had suggested.

Subject: [PATCH] dt-bindings: riscv: correct starfive visionfive 2 compatibles

Using "va" and "vb" doesn't match what's written on the board, or the
communications from StarFive.
Switching to using the silkscreened version number will ease confusion &
the risk of another spin of the board containing a "conflicting" version
identifier.

No, I'm sorry for being late here. The below definitely looks better to me.

I'll convert these both to Acked-by & send this as a real patch then.

So I think this is wrong, and the stdout-path should be uart3 instead.
Per the QSG [0], GPIO5/6 are the suggested UART Tx/Rx to use.
This appears to map to uart3 rather than uart0.
FWIW, uart3 is also the stdout-path for the v1, see:
arch/riscv/boot/dts/starfive/jh7100-common.dtsi

At least, that change is what I needed to do in order to use the
JH7110_VisionFive2_upstream branch, AFAICT matches what you've got in
this series.

Thanks,
Conor.

I went and re-tried things again today, but with the clk & pinctrl series
from the ML instead of that branch.
I'd gone and used that branch instead of the patches, as there were some
build issues with the pinctrl driver from the patches.
I fixed the build issues in the pinctrl driver and now uart0 works.

Looking at it again, it makes sense for uart0 to be serial0, given
there's pinconf stuff being done in this DT for pins 5 & 6 for uart0.

Perhaps by using that branch, I was using some older drivers etc given
it seems to mostly contain commits dating from November?
I'm still a bit confused about the whole thing, given I tried out a
whole load of branches to get something booting with ethernet support
that day!

Since this seems to work with the fixed pinctrl driver, I don't think
you need to change anything here.

Apologies for the noise!
Conor.

Is this a good idea when you have SKUs with 2, 4 & 8 GiB of DDR?

Anyways, I can't review this as I've got neither board nor
documentation, so with the above stuff sorted out:
Acked-by: Conor Dooley <conor.dooley@microchip.com>
I'll not apply it until the clock binding header is in my tree.

Thanks,
Conor.

I'm fine with this change. If no objection, I will modify it.

The VisionFive 2 board only has 4GB version and 8GB version now. Before
linux startup, we will change this property in dtb through u-boot to
make sure the board can boot up with the correct memory size.

Ah I see. Thanks.
