Hi Tibor

Its not a problem to bug me, but please also CC: the arm kernel
mailing list. This board port was contributed by Tero Jaasko
<tero.jaasko@gmail.com>, so its good to also ask him.

A basic question to start with. Are you using the default kernel
configuration for kirkwood? Which kernel version are you using?

Do you know what address it is using on the i2c bus? It looks like it
would be one of: 0x2c, 0x2d, 0x2e. Does you board also have the
adt7476?

You will need to edit arch/arm/boot/dts/kirkwood-nsa310.dts and add
something like:

                        lm85: lm85 at 2c {
                                compatible = "lm85";
                                reg = <0x2c>;
                        };

inside the i2c at 11000 node.

Do you see anything like:

Serial: 8250/16550 driver, 2 ports, IRQ sharing disabled
f1012000.serial: ttyS0 at MMIO 0xf1012000 (irq = 33) is a 16550A
console [ttyS0] enabled
f1012100.serial: ttyS1 at MMIO 0xf1012100 (irq = 34) is a 16550A

How do you mean not working? Is /sys/class/leds/ empty? Or when you
change the brightness value, nothing happens?

Hi Tibor

Which NSA310 do you actually have? Apparently there are actually two
variants:

http://zyxel.nas-central.org/wiki/Category:NSA-310

It could be yours is actually the rebranded TDC Homedisk. If so, we
should add a new .dts file for it.

Hello guys,

standard kernels, have been trying 3.9.8,3.9.9 and 3.10

The address is the same as the adt ones' but it is
recognized as a lm85. Sorry was a bit misleading. I could
make my sensors work via simply changing the type
from adt7476 to lm85

None at all. I only see the first "Serial:" line, then
nothing else, seems like the UART0 is stucked, badly mapped/initialized
at that time.

Sorry lame me, wasn't clear again :)
All the LEDs remain "uninitialized", all
remains green after bootup, haven't tried setting
them yet :(

This suggests you are missing SERIAL_OF_PLATFORM.

Try

make kirkwood_defconfig
make

and see if that kernel works any better.

Looking through the patch you pointed out, i think you will find some
work, some don't, and some have the wrong meaning.

We are going to need to add a new DTS file for this board. I can work
on this soon.

I have the one on the topmost picture, not the one labelled as "TDC".

Hi Tibor

I created a DTS file based on the tree you gave me.

Please could you try

https://github.com/lunn/linux.git branch v3.10-nsa310-tdc

and the DTS file arch/arm/boot/dts/kirkwood-nsa310-tdc.dts

Please use 

make kirkwood_defconfig
make

and it should have the lm85 built in.

The two different NSA310 are mostly similar, just a few different gpio
LEDs and buttons, so i might actually refactor the two dts files with
what is shared. But lets get your box working first.

Great. Probably was OF_SERIAL_PLATFORM

Ah, O.k. EXT4 is not part of kirkwood_defconfig. Hence it cannot mount
the root fs.

Please could you use make menuconfig and include it into the kernel
image. I will also update the patch later.

LEDs are not working because the GPIO driver is not loading.
I will see if i can spot an obvious typo etc.

WTF. Andrew. It works COMPLETELY.
The memory mapped GPIO was working from the .config (don't ask me how).

* sensors
* LEDs
* bootup works

Awesome work thanks a lot!!!!

You should have something similar.

I have no LEDs on this box, but you should should see entries in

/sys/class/leds

What you probably see in the kernel logs is lots of warnings from gpio
about deferred, but then they get repeated later and are successful.

Hi Tibor

For DT based board, hardware blinking is not supported, as far as i
remember.

Hello Andrew,

is there an example for "mixed machine setup" (if there is anything like 
that) ?
I'm thinking about:

* DT based initialization starts
* then if supported board based "after-DT-init-board-code" executes

similar what we have in board-*.c files just that it would be executed 
after kirkwood has initialized the board
based upon the .DTB
[I'm thinking about getting rid of the LED setup from the .DTB and move 
it back to .C land - at least for a trial]

Thanks,
Tibor

As a testing hack, just add the following to board-dt.c:

	if (of_machine_is_compatible("keymile,whizbang-board")) {
		/* GPIO hackery here */
	}

Ok, but isn't board-dt.c is the very first thing (kinda) which is 
executed prior the .DTB is parsed
and executed?
E.g. if I add the GPIO hack there, I assume that kirkwood and orion is 
already initialized.
Or is the board-dt.c executed after the .DTB is loaded/parsed?
Thanks,

The last line parses the dtb.  Perhaps late_initcall()?

NSA310 + DT

[Finn Hoffmann]

Hello,

I have tried to get a current Kernel running on my NSA310. Everything 
works well on Kernels before DT with the mentioned patches from 
https://github.com/peeter123/NSA310-320-debian .
I have linux-3.10.2 running and after I changed the dts file to lm85 
sensors and fanconrtol work but GPIO does not.
I tried https://github.com/lunn/linux/tree/v3.11-rc1-nsa310-tdc and 
linux-3.11.0-rc3.
Both have the problem that r8169 is not working:
r8169: eth0: unknown chipset (mac_version = 0).
and console is spammed with
r8169 0000:01:00.0 eth0: rtl_phyar_cond == 0 (loop: 20, delay: 25).
until I take eth0 down.
GPIO is working.

Any ideas?

Finn

Adding Andrew Lunn to the Cc: as he is more familiar with those DT
changes.  In future, please Cc myself, Andrew, and Gregory Clement so we
don't miss the email.

Hi Finn

Thanks for testing my tree. I based it on the patches found in 
https://github.com/peeter123/NSA310-320-debian.

The patch-3.6.9-nsa310.diff does not contain any changes to the
ethernet driver. So you best bet is to ask on the netdev mailing
list.

Once you have it solved, it would be nice if you can send a tested-by:
signoff to my patches.

Hi Thomas

That does not look good, does it?

Ok, now we have a memory window created, which looks better, but its
addresses are wrong.

Thanks for this log. I need a bit of time to analyze this with the
PCI-to-PCI bridge specification, and I'll cook up a new patch,
hopefully tomorrow.

Thanks again a lot for taking the time to report this bug and test the
patches,

Thanks!

Ok, here is another patch that completely disables prefetchable
support, which hopefully should make the PCI stuff fallback on normal
memory. Could you try this one, and again report lspci -v + the
contents of the debugfs file that lists the mbus windows?

I've worked more on the prefetchable support, but doing it right with
the PCI-to-PCI bridge emulation is a bit complex.

Thanks!

Now this looks good, we have both the PCIe memory and PCIe I/O windows
created.

I'll clean up the patch and send it, hopefully for the final 3.11.

Thanks again for all your testing!

Best regards,

Thomas, thank you for your Work.

I have a question about LED's:
Is it possible to have the powerled blinking while kernel is loading? 
Right now all LED's are turned off when the kernel starts.

I came across one curious thing: With Andrews kernel I had:
$ sensors
adt7476-i2c-0-2e

fan2: 0 RPM (min = 0 RPM)

(crit = +100.0??C, hyst = +96.0??C)

normally I have:

Yes, you can set a default trigger for GPIO LEDs. Just edit the
kirkwood-nsa310.dts file and add:

	linux,default-trigger	= "heartbeat";

into the GPIO LED that you want to see blinking once the kernel is
running. Note that it won't be blinking while the kernel is loading
(because loading the kernel is done by the bootloader), but it will
start blinking as soon as the kernel has initialized the GPIO LEDs.

I am not sure to understand which one you believe is correct and which
one is wrong, and how the wrong one is wrong. But I don't have much
sensor experience, maybe Andrew has more knowledge than me on this
stuff.

Note that the first above is an adt7476 and the other lm85.

There are multiple, slightly different NSA310 designs. Some have an
lm85, others have a adt7476. Which do you have? If you are using:

https://github.com/lunn/linux.git branch v3.11-rc1-nsa310-tdc you will
find two different DT descriptions for NSA310. See which works best
for you, kirkwood-nsa310.dtb or kirkwood-nsa310a.dtb.

There is a ADT7476RQZ chip on the board of my NSA310. I was only 
confused that both work.
But right now I can not reproduce that. I have changed the dts file back to
             adt7476: adt7476a at 2e {
                 compatible = "adt7476";
                 reg = <0x2e>;
             };
but sensors still says it is a lm85.

The LED's on after kernel is loaded, while starting up does not work.
            pmx_led_sys_green: pmx-led-sys-green {
                 marvell,pins = "mpp28";
                 marvell,function = "gpio";
                 linux,default-trigger = "heartbeat";
                 brightness = <255>;
             };
I first tried default-trigger, then I added brightness additionally but 
LED's wont turn on.

There is no sata hdd trigger and nand-disk does not trigger on sata hdd 
activity.

Can you manually turn the LED on, using /sys/class/led/.../brightness?
It could be we have the wrong GPIO line for the led. It would be good
if you could test them all, not just this one led.

They are out of tree patches. There was some discussion about SATA led
activity maybe 6 to 9 months ago. Maybe you can see why the suggested
patches got rejected. If i remember correctly, it was because they are
in the hot path.

All LED's work via brightness and trigger default-on.

On a quick look I have not found it but it is not that important for me.

Thomas,

I just came across one thing. Is it ok that I have different Marvell 
device with patched 3.11.0-rc3?
With 3.10.2 it has pci id 11ab:6281, with 3.11.0-rc3 and your patch it 
has 11ab:7846.

Yes, this is expected. 3.11-rc uses a completely new PCI driver for
Marvell platforms, that has a proper Device Tree binding. This driver
uses a very different strategy than the old driver in terms of MBus
window configuration, and to achieve this it relies on an emulated
PCI-to-PCI bridge. The numbers you're seeing are the one of the
emulated PCI-to-PCI bridge.

And the patch I've done fixes this PCI-to-PCI bridge emulation. BTW,
I've officially submitted the patch, which has been taken by the PCI
maintainer and will be part of one of the next 3.11-rc, and therefore
of the final 3.11. I mentioned you as Reported-by and thought git
send-email would automatically Cc you on the patch, but it did not.

Thanks again for your report!

Best regards,

Thomas
