Felipe, Roger,
Using Tony's current master branch, and enabling EHCI support, I see
the clock framework spitting loudly about the EHCI driver (full boot log
below.) The same thing happens on v3.8-rc7.
Any idea what's going on? Am I missing a set of fixes that's already
been posted?
On a related note, is anyone planning to fix the runtime PM problems in
this driver? It's still disabled by default in omap2plus_defconfig
because the driver keeps CORE from hitting retention, even when no
devices are attached.
Kevin

Looks like a couple of different things.
> [ 0.515747] usbhs_omap usbhs_omap: ehci_logic_fck failed:-2
Seems like the clk_get lookup failed here in usbhs_omap_probe. So from
this point on omap->ehci_logic_fck == -ENOENT. This bogus value gets
passed into all of the clk apis, which leads us to the below error.

This WARN gets tripped when a clock is enabled but not prepared. From
__clk_enable in drivers/clk/clk.c:
if (WARN_ON(clk->prepare_count == 0))
return -ESHUTDOWN;
So we're basically dereferencing a bogus struct clk pointer in
__clk_enable and the memory address of clk->prepare_count just happens
to be zero filled.
On a related note, even if the clk_get lookup did not fail this WARN
would still be hit since this driver never once calls clk_prepare.
Regards,
Mike

Thanks for pointing out. This series should fix the issues
https://lkml.org/lkml/2013/1/23/155
They should be on their way to linux-next.

I would be working on it. It is all about getting the silicon erratas
worked around and making sure USB suspend/resume works.

Great. But what about v3.8? I see the same problems in v3.8-rc7.

isn't it too late for v3.8 ? I guess the only way out would be to send
the patch for stable.
