This commit updates the USB Host stack to use the USB PHY driver. The
USB PHY and the OTG Controller should now both be setup/deleted using
usb_new_phy() and usb_del_phy() respectively.
- The hcd_install() now expects the USB PHY and OTG Contorller to be
already setup before it is called
- usb_host_install() now has an option to skip calling usb_del_phy() if
the user wants to setup their own USB PHY (e.g., in the case of using
and external PHY).
- CDC-ACM and MSC examples/test updated to use internal PHY

Implementation of an asynchronous MSC client used for USB Host disconnection test.
|
|
|
|
- The MSC client will:
|
|
- Register itself as a client
|
|
- Receive USB_HOST_CLIENT_EVENT_NEW_DEV event message, and open the device
|
|
- Allocate IN and OUT transfer objects for MSC SCSI transfers
|
|
- Trigger a single MSC SCSI transfer
|
|
- Split the data stage into multiple transfers (so that the endpoint multiple queued up transfers)
|
|
- Cause a disconnection mid-way through the data stage
|
|
- All of the transfers should be automatically deqeueud
|
|
- Then a USB_HOST_CLIENT_EVENT_DEV_GONE event should occur afterwards
|
|
- Free transfer objects
|
|
- Close device
|
|
- Deregister MSC client
