At the time, I had no such hardware to test this on, so I was hoping for more testers to give them a try in different environments, which apparently didn't happen. It fixed a dead USB port condition on host-mode enabled hardware, though. Well we probably should not merge patches without proper acks and tested-by:s in general as things just seem to keep breaking constantly otherwise. And things not working will keep people from using linux next which will lead into even less testing.. I'm fairly sure the patch causing your trouble has been in linux-next for a while before they hit the merge window, so people with gadget enabled musb could have noticed the breakage early enough. The feedback rate for patches to this driver posted to linux-usb is also usually low, unfortunately. I blame myself for not explicitly pointing out the fix. Instead I clubbed it with this series. http://marc.info/?l=linux-usbm=140109627505065w=4 Sorry for that. Right but the problem is that people are not touching linux next because it's constantly broken :) Anyway, breaking things is certainly not good, and I'm sorry for that. I'm just uncertain what detail in the procedure should be tweaked in order to prevent that from happening in the future. Well I guess somebody should run basic tests on this driver in linux next, that would probably solve the issues. I am doing it. Great, good to hear thanks :) Tony -- To unsubscribe from this list: send the line unsubscribe linux-usb in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
move ZTE CDMA device pid from zte_ev.c back to option.c and modify a parameter in zte_ev.ko
dear linuxfoundation:
I'm very sorry has some problems in before's submit. now i divided the
problems in two patches.
patch1:move ZTE CDMA device pid from zte_ev.c back to option.c.
reason: the pid of 0xfffe device can't re-connect succusfull when driven by
zte_ev, but work fine when driven by option.
move the pid 0xfffe from zte_ev.c back to option.c.

[PATCH 00/15] usb: dwc2: Add support for dual-role
From: Dinh Nguyen dingu...@altera.com Hi, This patch series combines the dwc2 host and gadget driver into a single dual-role driver. I have tested this on the SOCFPGA platform. I compile tested for bcm2835_defconfig and a PCI platform. I split up the patches to make the review a bit easier, but each individual patch can't really stand on it's own. Any comments/testing is greatly appreciated.

[PATCH 07/15] usb: dwc2: gadget: Do not fail probe if there isn't a clock node
From: Dinh Nguyen dingu...@altera.com
Since the dwc2 hcd driver is currently not looking for a clock node during
init, we should not completely fail if there isn't a clock provided.
Add a check for a valid clock before calling clock functions.

Since the dwc2 hcd driver is currently not looking for a clock node during

Add a check for a valid clock before calling clock functions.

I know I missed the first round of discussion where this was
suggested, but I don't think it's a good idea to pull the whole
hc_driver structure out into every platform implementation. It will
lead to duplication, then to future additions only being applied to
some of the implementations and everything getting out of sync. This
is already a problem with the PCI/plat split (e.g. the LPM functions
were only added to xhci-pci even though they should apply to both).
Also, if I'm not mistaken this code would fail to compile as a module
(you are referencing lots of symbols that are internal to the xhci-hcd
module).
I think at the very least you should add a function
xhci_default_driver(struct hc_driver *driver) to xhci-plat.c (or
even better to xhci.c and use it for PCI as well) that initializes all
function pointers to the default (internal) symbols, and can then be
overridden afterwards.

usb: musb: Ensure that cppi41 timer gets armed on premature DMA TX irq
Some TI chips raise the DMA complete interrupt before the actual
transfer has been completed. The code tries to busy wait for a few
microseconds and if that fails it arms an hrtimer to recheck. So far
so good, but that has the following issue:
CPU 0 CPU1
start_next_transfer(RQ1);
DMA interrupt
if (premature_irq(RQ1))
if (!hrtimer_active(timer))
hrtimer_start(timer);
hrtimer expires
timer-state = CALLBACK_RUNNING;
timer-fn()
cppi41_recheck_tx_req()
complete_request(RQ1);
if (requests_pending())
start_next_transfer(RQ2);
DMA interrupt
if (premature_irq(RQ2))
if (!hrtimer_active(timer))
hrtimer_start(timer);
timer-state = INACTIVE;
The premature interrupt of request2 on CPU1 does not arm the timer and
therefor the request completion never happens because it checks for
!hrtimer_active(). hrtimer_active() evaluates:
timer-state != HRTIMER_STATE_INACTIVE
which of course evaluates to true in the above case as timer-state is
CALLBACK_RUNNING.
That's clearly documented:
* A timer is active, when it is enqueued into the rbtree or the
* callback function is running or it's in the state of being migrated
* to another cpu.
But that's not what the code wants to check. The code wants to check
whether the timer is queued, i.e. whether its armed and waiting for
expiry.
We have a helper function for this: hrtimer_is_queued(). This
evaluates:
timer-state HRTIMER_STATE_QUEUED
So in the above case this evaluates to false and therefor forces the
DMA interrupt on CPU1 to call hrtimer_start().
Use hrtimer_is_queued() instead of hrtimer_active() and evrything is
good.

RE: [RESEND PATCH 00/15] usb: dwc2: Add support for dual-role
From: dingu...@altera.com [mailto:dingu...@altera.com] Sent: Friday, June 20, 2014 8:35 AM From: Dinh Nguyen dingu...@altera.com Apologies for the noise, but I got Paul Zimmerman's address wrong on the first send. Hi, This patch series combines the dwc2 host and gadget driver into a single dual-role driver. I have tested this on the SOCFPGA platform. I compile tested for bcm2835_defconfig and a PCI platform. I split up the patches to make the review a bit easier, but each individual patch can't really stand on it's own. Any comments/testing is greatly appreciated. Hi Dinh, I really appreciate your work on this, and from a quick glance, it looks like this will be acceptable once a few issues are taken care of. However, I am not going to do an in-depth review, or do any testing, until you submit a patch series that can be applied. Why? If I do a review and test of this series, then I will have to ask you to redo it into a form that can be applied. Then I would have to do a full review and test of _that_ series as well, to make sure that nothing got broken in the translation. So you are creating more work for me, yourself, and anyone else who might want to review/test this. Also, please do not post a patch series titled [PATCH] if you know that it should not be applied as-is. At least put an RFC in there so people will know it shouldn't be applied. Really, you should learn to use git properly, instead of doing a bunch of work without it, and then throwing everything in at the last minute so you can create a patch series. Git should be your friend, not your enemy ;) -- Paul -- To unsubscribe from this list: send the line unsubscribe linux-usb in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

gcc is perfectly capable of figuring that out. No need to use *inline*
outside the *.h files.

move ZTE CDMA device pid from zte_ev.c back to option.c
dear linuxfoundation:
I'm very sorry, i think i had been according to the
Documentation/SubmittingPatches to submit.
The pid of 0xfffe device re-connect network failed when driven by zte_ev,
but work fine when driven by option if we move the pid 0xfffe to option.
in order to re-connect sucessfull, we should move the pid 0xfffe from zte_ev.c
back to option.c.

uas regression in 3.15 with ASMedia 2105 SATA bridge / ASMT1051
After upgrading to kernel 3.15 my USB 3.0 HDD dock no longer works. In fact, as soon as I connect and power up a drive with the uas module loaded, I get a hard lockup and have to restart the system. Without the uas module loaded, the dock is detected but the drive is not, rendering it unusable. I had no problems at all with this hardware on kernel 3.14.
