Hi,

i need to NAK this series. the asiarf board is nothing more than the
official MTK EVB with AsiaRF written on it. this board is already
supported by linux (arch/arm/boot/dts/mt7623-evb.dts) please extend the
EVB dts file nstead of adding a duplicate and letting the original bitrot.

Well, I disagree.

First of all I'm not letting "the original" bitrot, because I have
nothing to do with that .dts! If anyone is to blame for letting it
bitrot since February 2016, pick your own nose:

http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/arch/arm/boot/dts/mt7623-evb.dts

Second, I have no Mediatek documentation or even picture to identify any
similarities between my board and that Mediatek EVB, so no, I can't hack
on the -evb.dts file. I wrote my .dts from scratch, not even having
access to /proc/device-tree on its 3.10 kernel for comparison.

Third, by your argumentation we shouldn't be adding, e.g., Odroid .dts
files either because they were based on a Samsung SMDK, or .dts files
for Amlogic TV boxes because they're almost identical to reference
designs, etc.
Users need to know which .dts file to choose, so having a sane .dts
filename is warranted. Depending on how similar they are, one could
either #include the -evb.dts or factor out a shared .dtsi, but that
takes us back to the previous point of hardly anyone having access to
EVB information to identify such a subset. Therefore duplicating trivial
nodes is the method of choice for all practical purposes - mt7623.dtsi
is getting reused just fine.

Comparing our two .dts files, mine has two more UART nodes enabled, the
U-Boot bootloader's baudrate set to actually get serial output, a
different board compatible string for identification, and I chose the
new dual-licensing header that is being requested for new DT files.

For lack of schematics I figured out UART1 by testing - continuity tests
for GND, console=ttySx,115200n8 and trial-and-error for RX/TX. Obviously
I can't do that for a board I don't have access to.
UART2 and UART0 pins were clear, but only UART2 was obvious from ttyMT2.

Do you actually have access to a Geek Force board yourself, or what are
you basing your claims on? Mine looks different from the Indiegogo
picture and thus has different identification from that on
https://wikidevi.com/wiki/AsiaRF_WS2977 (WS3301, MT7623N RFB_V10).

If you confirm the EVB's baudrate I can happily send that part your way.
I've seen 921600 on the Helio X20 96board for instance.

Also, none of what you've said justifies NAK'ing patch 4/4, which
applies to any mt7* and arm64 .dts, including yours.

While we're at it, I noticed that mainline has a "mediatek,mt7623-eth"
network driver but no corresponding .dtsi node. Talk about bitrot...

Regards,
Andreas

reading the rest of the email you seem to be quite agro about this.

what should i pick my nose about ? i made mt7623 work, then waited for
4.10-rc1 to be out for clk-mt2701 so that i can continue adding the
missing support

ok, that info is most likely under NDA

in that case add a dtsi file for the EVB and include it in your geek
board.dts and only update the compat string.

1) at the time we adde this the uart support was not ready
2) the bootloader i am using is a custom built one hence the random baudrate
3) you can just updae the license if you want to, no problem

you do have the EVB directly in front of you

i dont need the geek board as i have the EVB and they are identical

agreed, i never even mentioned 4/4

the idea is that we work together to make thins optimal. this is not a
you or is right. this is about the FOSS peer review process. please dont
be so agro.

to me it seems suboptimal to support 2 dts files for the same board.

Hi Andreas,

had a look last night why the ethernet dtsi was not added and it
obviously was not added as we were waiting for the clk-mt2701 to be
merged. the ethernet dtsi will have phandles pointing at the clk nodes
which did not exist at the time. same is true for the PWM code.

i sat down last night and worked out what pending patches i still have
for mt7623 and out of the ~80 required to get v4.4 working i only need
around 10 for v4.10-rc1.

i started to rebase these patches last night and will have time to test
them tomorrow or early next week. as the pwrap node alone is around 200
lines of devicetree we need to figure out a way to add this to the dts
files without duplicating it. i'll try to post a series early next week
that we can then discuss and rebase your geekboard patches on.

	John

Please re-read your reply above and my comments and reconsider your
attitude when replying in the future. It's not about whether these
patches go in or not, it's about your wording. And that continues with
aggressively throwing around the term "agro" in two mails already. I
don't see anything aggressive or angry in my original cover letter that
would've prompted your reply and can only interpret that as your own
frustration with your mt7623 progress. Instead you should've taken the
time to explain a bit better what you really meant, then we could've
spared or shortened this lengthy discussion and have a v2 already.

Don't blame _me_ for "bitrot" of a file _you_ added almost a year ago
that did not see any updates since.

Nothing wrong with you not working on something, just don't blame me for
it then, especially when I don't (knowingly) have that hardware and have
never come in touch with it before. I am new to linux-mediatek and had
checked LAKML in vein for any mt7623 patches before sending mine.

The question that I am not in a position to answer is: Are those two
boards identical or just very similar? Paul in CC can hopefully clarify
this when he is back. Matthias as maintainer has also remained silent.

Well, did the _original_ bootloader use 115200? In that case we could
update -evb.dts with it, and you could still override it via console=
for your custom build.

Or maybe having source access you could even contribute to mainline
U-Boot, so we can all work on the same codebase? I read a BPi-R2 is
coming up with mt7623, so booting without appended .dtb and uImage will
come in handy for more people than just EVB owners and Geek Force
backers. I'd happily contribute to making bootefi command work.

OK, will gladly look into the feasibility.

So... 4) add my UART nodes to your -evb.dts? Any nitpicks on the actual
patch 3/4?

You replied to the cover letter 0/4 "i need to NAK this series" - and
series includes all four patches. Therefore my frustration with your
hip-shot reply. If you haven't read the patch, don't NAK it!

In fact still no one replied to it at all, even now that you're aware of
its existence.

See above, please reconsider your tone. Peer review is no excuse for
rude and destructive behavior towards contributors you don't know.

Had you looked at the lists and codebase you would know that I am not
new to FOSS.

And please stop writing "agro", it sounds like some pothead making a
peace sign; not helpful among professional software developers.

Taking the time to start your sentences with a capital letter would also
be a respectful gesture.

> to me it seems suboptimal to support 2 dts files for the same board.

If it is the identical board, then we are in violent agreement. I just
find all your replies to me offensive so far, I don't know you and thus
have no reason to trust your unsubstantiated claims about my board.

Regards,

Andreas

Sounds like a plan. Many thanks!
