| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Port of Linux patch https://patchwork.kernel.org/patch/10766235/ The HW can swap the USB differential-pair (D+/D-) for each port separately. So the USB signals can be re-aligned with a misplaced USB connector on the PCB.

To fix all of the above introduce xhci_init_event_cmd_trb(), that will initialize all of the fileds to desired values only once as well as taking care of endianness.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Driver's .submit_control() callback can and will be called with buffer set to NULL (and length set to 0), so we need to make sure that we don't try to DMA sync the buffer in that case.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Gadget update to 3.15 imported Linux patch e117e742d310 ("usb: gadget: add "maxpacket_limit" field to struct usb_ep"): This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. However said update didn't bring in all driver changes. Do it now.

| | | | | | | | | | | | | | | | | | | | | | | | | | ci_udc_unregister() used to unregister "the controller". Since we may register multiple chipidea devices we called ci_udc_unregister() for each of them. This led to messages like: ERROR: imx-usb 53f80000.usb: gadget not registered.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | An ehci can be registered with ehci_register which is passed a struct device_d *. In that case the priv pointer may already be used by the caller, so we must not use it in the ehci code. At least for the Atmel ehci driver this fixes a bug, here dev->priv is set two times to different values. Since we need dev->priv in the ehci code to get the controller in ehci_detect() we can no longer implement that without the help of the caller, hence we eport ehci_detect() and epect it to be called by the code which registers a ehci host.
