[PATCH RFC] usb: chipidea: add support for usb_phy in generic usb2

Signed-off-by: Baruch Siach --- drivers/usb/chipidea/ci_hdrc_usb2.c | 5 + 1 file changed, 5 insertions(+) I'm sending this as RFC as I'm not sure this is the right thing to do. There seems to be a move away from USB specific PHY drivers towards the generic PHY framework (drivers/phy). The t

[PATCH 2/2] Chipidea: Set connect-at-fullspeed bit when entering host mode if CI_HDRC_FORCE_FULLSPEED is set in the platform data

PORTSC_PFSC is not set on entering host mode which means the USB OTG controller will attempt to enumerate USB devices at high speed even when the CI_HDRC_FORCE_FULLSPEED flag is set in the platform data. This patch ensures it is set right before host mode operations begin if needed. Signed-off-by

Re: xhci_hcd: ERROR Transfer event for disabled endpoint or incorrect stream ring

Interestingly, after connecting a different external USB storage dock (this time it is USB 2.0) to the internal USB connector of the PCIe expansion card (the internal connector is connected to a front USB connection panel) I don't see the same error. But this time the USB mode used is not uas, but

May also be of interest: I've used the external USB 3.0 dock with the 2 TB HDD now for > 10 hours and no instability or crashes of any kind. I'm copying video files and watching them from the USB device in question works as expected. I'm running kernel 3.18.1-gentoo on amd64. Please let me know i

[PATCH 1/2] USB: console: fix uninitialised ldisc semaphore

The USB console currently allocates a temporary fake tty which is used to pass terminal settings to the underlying serial driver. The tty struct is not fully initialised, something which can lead to a lockdep warning (or worse) if a serial driver tries to acquire a line-discipline reference:

Possible race condition in USB gadget probing?

Hi, I’ve run into a problem which I suspect is to with how usb_gadget_probe_driver is implemented in drivers/usb/gadget/udc/udc-core.c I have an embedded system that uses the Chipidea OTG controller. Unfortunately, when it boots up, the driver is loaded but there’s no USB gadget that gets atta
