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

This commit fixes the following bugs in the HCD
- HCD control pipes fill incorrect transfer size
_buffer_fill_ctrl() would fill the transfer descriptors length with
wLength instead of transfer->num_bytes. Therefore, the remaining length
would be incorrect when a control transfer requests more bytes than are
available.
- Fix USB_TRANSFER_FLAG_ZERO_PACK behavior
The previous behavior of USB_TRANSFER_FLAG_ZERO_PACK was incorrect, and did not
support interrupt pipes. A zero length packet can now be added to Bulk/Interrupt
OUT transfers where the length is a multiple of the endpoint's MPS.
- Fixed HCD port suspend and resume test case
Halting a control pipe mid control transfer can lead some test devices to get stuck
peripheral enable/disable usually should be managed by driver itself,
so make it as espressif private APIs, not recommended for user to use it
in application code.
However, if user want to re-write the driver or ports to other platform,
this is still possible by including the header in this way:
"esp_private/peripheral_ctrl.h"
This commit fixes how the USB Host HCD handles sudden disconnections.
Bugs:
- HW channels remain active when the port suddenly disconnects, and
previously the channel would be disabled by setting the disabled bit,
then waiting for a disabled interrupt. However, ISOC channels do not
generate the disabled interrupt when the port is invalid, thus leading
to tasks getting indefinitely blocked in hcd_pipe_command().
Fix:
On a sudden disconnection, forcibly treat all channels as halted even
if their HCCHAR.ChEna bit is still set. We do a soft reset after a port
error anyways, so the channels will eventually be reset.

This commit adds the preliminary version of the USB Host Library. This commit contains:
- USBH (USB Host Driver)
- Hub Driver that only supports a single device and device enumeration
- USB Host Library (asychronous API)
- Test cases for USB Host Library asychronous API
The following changes were made to the existing HCD:
- Removed HCD_PIPE_STATE_INVALID. Pipes are no longer invalidated
- Changed pipe commands to halt, flush, and clear. Pipes need to be manually
halted, flush, and cleared.
- Halting and flushing a pipe will execute the pipe callback if it causes a
HCD_PIPE_EVENT_URB_DONE event
This commit fixes the following bugs with the HCD and USB Host HAL
- Make the setting to periodic frame list and scheduling to occur after
a reset command
- All port errors states should put the port into the HCD_PORT_STATE_RECOVERY
state.
- Fixed incorrect return type of hcd_port_command() function
This commit changes the IRP (I/O Request Packet) structure to
the URB (USB Request Block) in order to represent USB transfers
in the host stack. The new URB strcuture:
- Add extra safety with const fields
- Allows each layer of the stack to add their own overhead variables
The HCD layer API and tests have been updated to use this new URB structure
This commit adds support for interrupt and isochronous pipes to the HCD:
- HCD now internally uses double buffering
- Added test cases for interrupt and isochronous transfers
- Reorganized test cases for each transfer type
- Updated API comments and maintainer's notes
Some minor bugs were also fixed
This commit updates the HCD so that transfer requests are no longer used.
The USB IRP object is updated so that the it can be directly passed to the HCD
to start a transfer. HCD API, tests, and documentation updated accordingly.
This commit separates out the common USB types used throughout most of the stack into its
own header file inside the USB component. The types used in the USB HAL are now exclusive
to the HAL.
