* dm: usb: Convert usb_storage to driver modelSimon Glass2015-04-18-2/+49
| | | | | | | | Add support for scanning USB storage devices with driver model. This mostly involves adding a USB device ID for storage devices. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Marek Vasut <marex@denx.de>
* dm: usb: Move storage device scanning into its own functionSimon Glass2015-04-18-38/+59
| | | | | | | | | | The usb_stor_scan() function is quite long, so split out the code that scans each device into its own function. Also, rather than setting up the block device list once at the start, set it up as each device is scanned. This makes it possible to use this code from driver model.

| | | | | | | This reverts commit cd749658d5994978579628a6333e5c2a6c8ec632. The conflicts with this commit are hard for me to figure out. I will re-apply it later.

| | | | | | | | | | | | | | This function now calls usb_setup_device() to set up the device and usb_hub_probe() to check if it is a hub. The XHCI special case is now a parameter to usb_setup_device(). The latter will be used by the USB uclass when it is added, since it does not rely on any CONFIGs or legacy data structures.

* dm: usb: Move descriptor setup code into its own functionSimon Glass2015-04-18-65/+82
| | | | | | | | | | | | | | | | usb_new_device() is far too long and does far too much. As a first step, move the code that does initial setup and reads a descriptor into its own function called usb_setup_descriptor(). For XHCI the init order is different - we set up the device but don't actually read the descriptor until after we set an address. Support this option as a parameter to usb_setup_descriptor(). Avoid changing this torturous code more than necessary to make it easy to review. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Marek Vasut <marex@denx.de>
