| * drivers: usb: fsl: Workaround for Erratum A004477Nikhil Badola2015-05-04-0/+10
| | | | | | | | | | | | | | | | | | | | Add a delay of 1 microsecond before issuing soft reset to the controller to let ongoing ULPI transaction complete. This prevents corruption of ULPI Function Control Register which eventually prevents phy clock from entering to low power mode Signed-off-by: Nikhil Badola <nikhil.badola@freescale.com> Reviewed-by: York Sun <yorksun@freescale.com>
* | sunxi: usb: Do not call phy_probe from hcd codeHans de Goede2015-05-04-12/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 2/3 usb-phys on the sunxi SoCs are really a single separate functional block, and are modelled as such in devicetree. So once we've moved all the sunxi usb code to the driver-model then phy_probe will be called once for the entire block from the driver-model enumeration code. Move to this now as this also avoids problems with phy_probe being called multiple times once we introduce ohci support. This also allows us to get rid of the sunxi_usb_phy_enabled_count variable as phy_probe now is guaranteed to be called only once. Since we're effectively rewriting the probe / remove functions, move them to the end of the file while we are at it, as that is the most logical place for them.

Also change the verbs & nouns in the suffix to match the verbs & nouns used in the Linux kernels generic phy framework. This patch purely renames things, it contains no functional changes.

| | | | | | | | | | | | | | | | | | | | | | | | The sunxi "usbc" code is mostly about phy setup, but currently also sets up the host controller clocks, which is something which really belongs in the host controller drivers, so move it there. This is a preparation patch for moving the sunxi ehci code to the driver model and for adding ohci support.

* 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.

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.
