| | | | | | | | | | | | Some controllers support OTG (on-the-go) where they can operate as either host or device. The gadget layer in U-Boot supports this.

* dm: usb: Bind generic USB devices when there is no driverSimon Glass2015-04-18-1/+17
| | | | | | | | | | | | | | | | | At present USB devices with no driver model driver cannot be seen in the device list, and we fail to set them up correctly. This means they cannot be used. While having real drivers that support driver model for all USB devices is the eventual goal, we are not there yet. As a stop-gap, add a generic USB driver which is bound when we do not have a real driver. This allows the device to be set up and shown on the bus. It also allows ad-hoc code (such as usb_ether) to find these devices and set them up. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Marek Vasut <marex@denx.de>
* dm: usb: Allow USB drivers to be declared and auto-probedSimon Glass2015-04-18-2/+204
| | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | Move the bulk of the code in usb_lowlevel_init() into a separate function which will also be used by driver model. Keep the CONFIG options out of this function by providing a tweak flag for Faraday. We need to avoid using CONFIG options in driver model code where possible, since it makes it impossible to use multiple controllers in that code where they have different options. The CONFIG_EHCI_HCD_INIT_AFTER_RESET option is also kept out of the common init function. With driver model the controller will be able to perform this extra init itself after registering with the EHCI layer.

* dm: usb: tegra: Store the controller type explicitlySimon Glass2015-04-18-6/+24
| | | | | | | | | | | | | | | | | At present the tegra driver uses a separate pointer to know which controller type is in use. This works because only one controller type is used at a time. With driver model we want to make the controller state hermetic in the sense that it is not necessary to look elsewhere to know the controller type. This will permit a controller to implement the EHCI weak functions without reference to global data structures. To achieve this, define an enum for the controller type and store it with the information on each EHCI controller.

| | | | | | | | | | | | | | | | | | | | | | | | | | VBUS detection could be needed not only by the musb code (to prevent host mode), but also by e.g. gadget drivers to start only when a cable is connected. In addition, this allows more flexibility in vbus detection, as it could easily be extended to other USBC indexes. Eventually, this would help making musb support independent from a hardcoded USB controller index (0).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The "fastboot reboot-bootloader" command is defined to re-enter into fastboot mode after rebooting into bootloader. This command is usually used after updating bootloader via fastboot. This commit implements only a generic side of the command - setting of the reset flag and then resetting. Setting of the reset flag is implemented using __weak fb_set_reboot_flag() function. The actual setting and checking of the reset flag should be implemented by a boot script and/or board/SoC specific code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | be LST It turned out that current dwc3 gadget code is preparing multiple TRBs for a transfer. Unfortunately, when multiple requests are in the same queue, only for the last one the LST (last) ctrl bit is set. Due to that dwc3 HW executes all TRBs up till the one marked as last. Unfortunately, UMS requires call of ->complete callback after any send TRB. This is the reason for "hangs" in executing UMS.
