* usb: add device connection/disconnection detectionVincent Palatin2015-05-14-0/+2

* dm: usb: Add support for companion controllersHans de Goede2015-05-14-0/+3
| | | | | | | | | | | | | | 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 Goede2015-05-14-1/+47
| | | | | | | | | | | | | | | 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>
* dm: usb: Copy over usb_device values from usb_scan_device() to final usb_deviceHans de Goede2015-05-05-7/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | Make usb_get_bus easier to use for callers, by directly returning the bus rather then returning it via a pass-by-ref argument. This also removes the error checking from the current callers, as we already have an assert() for bus not being NULL in usb_get_bus().

* dm: usb: Allow USB drivers to be declared and auto-probedSimon Glass2015-04-18-0/+107
| | | | | | | | | | | | | | | | | | | | | | | | | USB devices in U-Boot are currently probed only after all devices have been enumerated. Each type of device is probed by custom code, e.g.: - USB storage - Keyboard - Ethernet With driver model this approach doesn't work very well. We could build a picture of the bus and then go back and add the devices later, but this means that the data structures are incomplete for quite a while. It also does not follow the model of being able to bind a device when we discover it. We would prefer to have devices automatically be bound as the device is enumerated. This allows us to attach drivers to particular USB classes or product/vendor IDs. This is the method used by Linux. Add the required #defines from Linux, a way of declaring a USB driver and the logic to locate the correct driver given the USB device's descriptors.

* musb-new: Fix reset sequence when in host modeHans de Goede2015-01-18-0/+5
| | | | | | | | | | | | | | | | | | | | | | This commit fixes a number of issues with the reset sequence of musb-new in host mode: 1) Our usb device probe relies on a second device reset being done after the first descriptors read. Factor the musb reset code into a usb_reset_root_port function (and add this as an empty define for other controllers), and call this when a device has no parent. 2) Just like with normal usb controllers there needs to be a delay after reset, for normal usb controllers, this is handled in hub_port_reset, add a delay to usb_reset_root_port. 3) Sync the musb reset sequence with the upstream kernel, clear all bits of power except bits 4-7, and increase the time reset is asserted to 50 ms. With these fixes an usb keyboard I have now always enumerates properly, where as earlier it would only enumerare properly once every 5 tries. Signed-off-by: Hans de Goede <hdegoede@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | Former usb_cable_connected() patch broke compilation of boards which do not support this feature. I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added its default implementation to gadget downloader driver code. There's only one driver of this kind and it's unlikely there'll be another, so there's no point in keeping it in /common. Previously this function was declared in usb.h. I've moved it, since it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended for USB host implementation. Existing code, confronted with default -EOPNOTSUPP return value, continues as if the cable was connected. CONFIG_USB_CABLE_CHECK was removed.

* usb: use linux/usb/ch9.h instead of usbdescriptors.hIlya Yanok2012-11-20-12/+3
| | | | | | | | | | | | | | | | | | | | | | Linux usb/ch9.h seems to have all the same information (and more) as usbdescriptors.h so use the former instead of the later one. As a consequense of this change USB_SPEED_* values don't correspond directly to EHCI speed encoding anymore, I've added necessary recoding in EHCI driver. Also there is no point to put speed into pipe anymore so it's removed and a bunch of host drivers fixed to look at usb_device->speed instead. Old usbdescriptors.h included is not removed as it seems to be used by old USB device code. This makes usb.h and usbdevice.h incompatible. Fortunately the only place that tries to include both are the old MUSB code and it needs usb.h only for USB_DMA_MINALIGN used in aligned attribute on musb_regs structure but this attribute seems to be unneeded (old MUSB code doesn't support any DMA at all).
