* | sunxi: ohci: Add ohci usb host controller supportHans de Goede2015-05-142-0/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds support for the OHCI companion controller, which makes usb-1 devices directly plugged into to usb root port work. Note for now this switches usb-keyboard support for sunxi back from int-queue support to the old interrupt polling method. Adding int-queue support to the ohci code and switching back to int-queue support is in the works.

* | usb: ohci: Skip unnecessary mdelay(1) calls in various placesHans de Goede2015-05-141-9/+20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For some reason the ohci code is full with: #ifdef DEBUG pkt_print(...) #else mdelay(1); #endif AFAICT there is no reason for the mdelay(1) calls. This commit disables them when building the ohci code for new driver-model using boards. It leaves the mdelay(1) calls in place when building for older boards, so as to avoid causing any regressions there. Signed-off-by: Hans de Goede <hdegoede@redhat.com>
* | usb: ohci: Remove unnecessary delays from hc_start and power power-on pathsHans de Goede2015-05-141-4/+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.

* | usb: ohci: Do not resubmit and leak urbs for interrupt packetsHans de Goede2015-05-141-39/+2
| | | | | | | | | | | | | | | | | | | | | | The u-boot usb code uses polling for all endpoints, including interrupt endpoints, so urbs should never be automatically resubmitted. This also fixes a leak of the urb, as submit_int_msg() did not check if an already re-submitted urb exists before creating a new one.

* | dm: usb: Do not scan companion buses if no devices where handed overHans de Goede2015-05-141-8/+34
| | | | | | | | | | | | | | | | | | | | | | | | USB scanning is slow, and there is no need to scan the companion buses if no usb devices where handed over to the companinon controllers by any of the main controllers. This saves e.g. 2 seconds when booting a A10 OLinuxIno Lime with no USB-1 devices plugged into the root usb ports.

* | dm: usb: Add support for companion controllersHans de Goede2015-05-141-5/+28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | USB companion controllers must be scanned after the main controller has been scanned, so that any devices which the main controller which to hand over to the companion have actually been handed over before we scan the companion. As there are no guarantees that this will magically happen in the right order, split the scanning of the buses in 2 phases, first main controllers, and then companion controllers.

* | dm: usb: Add support for interrupt queues to the dm usb codeHans de Goede2015-05-142-0/+62
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Interrupt endpoints typically are polled for a long time by the usb controller before they return anything, so calls to submit_int_msg() can take a long time to complete this. To avoid this the u-boot code has the an interrupt queue mechanism / API, add support for this to the driver-model usb code and implement it for the dm ehci code. See the added doc comments for more details. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Simon Glass <sjg@chromium.org>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ehci driver model code for finding the first upstream usb-2 hub before this commit has a number of issues: 1) "if (!ttdev->speed != USB_SPEED_HIGH)" does not work because the '!' takes presedence over the '!=' this should simply be "if (ttdev->speed == USB_SPEED_HIGH)" 2) It makes ttdev point to the first upstream usb-2 hub, but ttdev should point to the last usb-1 device before the first usb-2 hub (when going upstream from the device), as ttdev is used to find the port of the first usb-2 hub to which the the last usb-1 device is connected. 3) parent_devnum however should be set to the devnum of the first usb-2 hub, so we need to keep pointers around to both usb_device structs. To complicate things further during enumeration usb_device.dev will point to the parent udevice, where as during normal use it will point to the actual udevice, we must handle both cases correctly. This commit fixes all this making usb-1 devices attached to usb-2 hubs, including usb-1 devices attached to usb-1 hubs attached to usb-2 hubs, work.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we copy over a number of usb_device values stored in the on stack struct usb_device probed in usb_scan_device() to the final driver-model managed struct usb_device in usb_child_pre_probe() through usb_device_platdata, and then call usb_select_config() to fill in the rest. There are 3 problems with this approach: 1) It does not fill in enough fields before calling usb_select_config(), specifically it does not fill in ep0's maxpacketsize causing a div by zero exception in the ehci driver. 2) It unnecessarily redoes a number of usb requests making usb probing slower 3) Calling usb_select_config() a second time fails on some usb-1 devices plugged into usb-2 hubs, causing u-boot to not recognize these devices. This commit fixes these issues by removing (*) the usb_select_config() call from usb_child_pre_probe(), and instead of copying over things field by field through usb_device_platdata, store a pointer to the in stack usb_device (which is still valid when usb_child_pre_probe() gets called) and copy over the entire struct. *) Except for devices which are explictly instantiated through device-tree rather then discovered through usb_scan_device() such as emulated usb devices in the sandbox.
