* usb: gadget: fastboot: Dequeue the previous IN request for the current requestPaul Kocialkowski2015-07-22-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Recent versions of the fastboot tool will query the partition type before doing an operation on a partition (such as erase, flash, etc). It will then submit the operation as soon as the response for the partition type is received. Usually, the MUSB controller will see that the partition type request return status was read by the host at the very same time as the actual operation request is submitted by the host. However, the operation will be read first (int_rx is handled first in musb_interrupt) and after it is completed, the fastboot USB gadget driver will send another return status. Hence, this happens before the musb gadget framework has had a chance to handle the previous acknowledgement that the host read the return status and dequeue the request. The host will then usually empty the FIFO by the time musb_interrupt gets around handling the return status acknowledgement (for the previous request, this is still on the same musb_interrupt call), so no other interrupt is generated and the most recent return status acknowledgement remains unaccounted for. It will then be used as a response for the next command, and the proper response for it will be delayed to the next command, and so on. Dequeuing the previous IN request in the fastboot code ensures that no previous return status remains. It is acceptable to do it since there is no callback to it anyways.

* usb: gadget: fastboot: Request status and length check in rx handlerPaul Kocialkowski2015-07-22-5/+6
| | | | | | | | | This avoids handling requests that have an error status or no data. In particular, this avoids showing unnecessary error messages when the USB gadget gets disconnected (e.g. with fastboot continue) and the fastboot USB gadget driver sends an error back to the host (that has disconnected already).

* usb: gadget: Weak board_usb_init/cleanup definitions in USB download gadget codePaul Kocialkowski2015-07-22-0/+13
| | | | | | | | | | | | Weak versions of board_usb_init and board_usb_cleanup are defined in common USB host code, but it is also used for USB device gadgets, so we also need a weak definition of it when there is no USB host enabled. Both weak definitions do not conflict. Signed-off-by: Paul Kocialkowski <contact@paulk.fr> Tested-by: Lukasz Majewski <l.majewski@samsung.com> Test HW: Odroid_XU3 (Exynos5422), trats (Exynos4210)

| | | | | | | | | | | | USB download gadget functions such as thor and dfu have a separate config option for the USB gadget part of the code, independent from the command part. This switches the fastboot USB gadget to the same scheme, for better consistency.

* usb: ehci: Properly deal with data toggle for interrupt endpointsHans de Goede2015-06-19-7/+19
| | | | | | | | | | | | | Without this we loose every other interrupt packet. We never noticed this because with keyboards the packets which we were loosing would normally be key release packets. But now that we do keyrepeat in software instead of relying on the hid idle functionality, missing a release will result in key repeat triggering. This commit fixes this.

* usb: ohci: Do not reuse ed for interrupt endpoints of different devicesHans de Goede2015-05-14-1/+38
| | | | | | | | | | | | | | | | | | | When submitting interrupt packets to an endpoint we only link in the ed once to avoid some races surrounding unlinking of periodic endpoints, but we share one ohci_device struct / one set of ed-s for all devices, which means that if we have an interrupt endpoint at endpoint 1 with one device, and a non interrupt endpoint 1 with another device we end up with the same ed linked into both the periodic and async lists, which is not good (tm). This commit switches over to using separate ohci_device structs, and thus separate ed-s for devices with interrupt endpoints, fixing this. This fixes e.g. matching a usb storage device and keyboard on the same usb-1 hub not working. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Reviewed-by: Marek Vasut <marex@denx.de>

* usb: ohci: Remove unnecessary delays from hc_start and power power-on pathsHans de Goede2015-05-14-4/+0
| | | | | | | | | | | | The usb spec says that we must wait a minimum amount of time after port power on (exact time is in the hub descriptor), this is something which we must not only do for root ports but also for external hub ports, which is why the common usb_hub code already waits a full second after powering up ports. Having a separate wait for just the root hub in the ohci-hcd code only leads to doing the waiting twice for the root ports, so drop the wait from the ohci-hcd code.
