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

Test HCD ISOC pipe URBs
|
|
|
|
Purpose:
|
|
- Test that an isochronous pipe can be created
|
|
- URBs can be created and enqueued to the isoc pipe pipe
|
|
- isoc pipe returns HCD_PIPE_EVENT_URB_DONE for completed URBs
|
|
- Test utilizes ISOC OUT transfers and do not require ACKs. So the isoc pipe will target a non existing endpoint
|
|
|
|
Procedure:
|
|
- Setup HCD and wait for connection
|
|
- Allocate default pipe and enumerate the device
|
|
- Allocate an isochronous pipe and multiple URBs. Each URB should contain multiple packets to test HCD's ability to
|
|
schedule an URB across multiple intervals.
|
|
- Enqueue those URBs
|
|
- Expect HCD_PIPE_EVENT_URB_DONE for each URB. Verify that data is correct using logic analyzer
|
|
- Deallocate URBs
|
|
- Teardown

Test a port sudden disconnect with an active ISOC pipe
|
|
|
|
Purpose: Test that when sudden disconnection happens on an HCD port, the ISOC pipe will
|
|
- Remain active after the HCD_PORT_EVENT_SUDDEN_DISCONN port event
|
|
- ISOC pipe can be halted
|
|
- ISOC pipe can be flushed (and transfers status are updated accordingly)
|
|
|
|
Procedure:
|
|
- Setup HCD and wait for connection
|
|
- Allocate default pipe and enumerate the device
|
|
- Allocate an isochronous pipe and multiple URBs. Each URB should contain multiple packets to test HCD's ability to
|
|
schedule an URB across multiple intervals.
|
|
- Enqueue those URBs
|
|
- Trigger a disconnect after a short delay
|
|
- Check that HCD_PORT_EVENT_SUDDEN_DISCONN event is generated. Handle that port event.
|
|
- Check that both pipes remain in the HCD_PIPE_STATE_ACTIVE after the port error.
|
|
- Check that both pipes pipe can be halted.
|
|
- Check that the default pipe can be flushed. A HCD_PIPE_EVENT_URB_DONE event should be generated for the ISOC pipe
|
|
because it had enqueued URBs.
|
|
- Check that all URBs can be dequeued and their status is updated
|
|
- Free both pipes
|
|
- Teardown
