Thanks, pushed your patch.

I think the earlier patch chunk has gotten auto-hosed by git merge in
Juha's recent merge:

http://source.mvista.com/git/gitweb.cgi?p=linux-omap-2.6.git;a=commit;h=330c1eb9a689973326cdece277d0b4b409833bb9

Mika & Dirk, can you guys check if some of the other audio files got
hosed or some old audio files got added back?

Regards,

Tony

Mmmh, seems that something is going on here I don't
understand completely ;(

While building modules with most recent git I get two
warnings (or better errors, modules are not build):

WARNING: "tlv320aic23_write_value"
[sound/arm/omap/snd-omap-alsa-aic23.ko] undefined!
WARNING: "usb_disconnect" [drivers/usb/host/ohci-hcd.ko]
undefined!

Not sure if USB is OMAP related, but aic is. Looking at

http://source.mvista.com/git/gitweb.cgi?p=linux-omap-2.6.git;a=blobdiff;h=fac8d6b7518032f54869cc309328e812e16892be;hp=7fdd1d3608b2c41141901acff4b79df27b0f53df;hb=51c0cddf5027bd4e5c1903845047d7d7e266c79b;f=drivers/i2c/chips/tlv320aic23.c

shows that from function names and variables 'tlv320' was
removed. However, commitdiff only shows the small (correct)
patch.

Patch in seperate mail.

Any ideas about USB? Seems that it comes from
drivers/usb/host/ohci-omap.c

Regards

Dirk

I think the sound/arm/omap-aic23.h has appeared as a resulf of that and
can be removed. The new version is nowadays in
sound/arm/omap/omap-alsa-aic23.h

Of course, it hasn't been exported for a while now.

I see a curious and pointless routine, ohci_omap_host_enable(), which
isn't called from anywhere I can see, which wants usb_disconnect().

Try deleting that routine.

tahvo-usb.c uses ohci_omap_host_enable():

./drivers/cbus/tahvo-usb.c:88:extern int 
ohci_omap_host_enable(struct usb_bus *host, int enable);
./drivers/cbus/tahvo-usb.c:248: 
ohci_omap_host_enable(tu->otg.host, 1);
./drivers/cbus/tahvo-usb.c:266: 
ohci_omap_host_enable(tu->otg.host, 0);
./drivers/cbus/tahvo-usb.c:300: 
ohci_omap_host_enable(tu->otg.host, 0);
./drivers/cbus/tahvo-usb.c:338: 
ohci_omap_host_enable(tu->otg.host, 0);
./drivers/cbus/tahvo-usb.c:431: ohci_omap_host_enable(host, 0);

And so it does.  That would be a bug in how the Tahvo transceiver is
trying to activate the USB host.  It should be able to just use
the normal power management suspend and resume calls... certainly
there's no benefit to creating transceiver-specific backdoors into
usbcore for runtime PM.

Anybody like to fix and test tahvo-usb.c regarding this? 
Then we could remove ohci_omap_host_enable() from 
drivers/usb/host/ohci-omap.c .

I will work on this, because we need this feature.

Re: Undefined usb_disconnect

[Dirk Behme]

Hi,

with recent git I still get

WARNING: "usb_disconnect" [drivers/usb/host/ohci-hcd.ko] 
undefined!

What's about the patch

http://linux.omap.com/pipermail/linux-omap-open-source/2006-May/007071.html

to be able to remove this?

Best regards

Dirk

Try the attached patch instead ... it fixes some other glitches
in the OMAP bus glue, as well as those.

- Dave





[-- Attachment #2: ohci-omap.patch --]
[-- Type: text/x-diff, Size: 8626 bytes --]

Various fixes for the OHCI OMAP glue:

 - Properly use the usbcore HCD lifecycle entry points

 - Remove calls to non-exported usbcore routines.

 - Stop inappropriate export of some bus glue calls

Plus remove some extra whitespace.

Okay, hanks for the patch! I think we should apply it until

http://linux.omap.com/pipermail/linux-omap-open-source/2006-May/007071.html

is reworked and ready for inclusion.

Thanks

superset of the patch from Hiroshi ...

I'll push this today slightly updated. Sorry, I should have pushed
this earlier.

Dave, I assume you will eventually send this upstream through your
USB channels so I did not tag this as a ARM: OMAP: patch.
