5aba179c34 usb: mtu3: fix the failure of qmu stop 
This happens when do stress test of uvc stream on/off which will
enable/disable endpoints. uvc has four tx requests, and may disable
endpoint between queue tx requests as following:
    enable ep --> start qmu
    queue tx request0
    queue tx request1
    queue tx request2 --> resume qmu
    disable ep --> stop qmu may fail [1]
    queue tx request3 --> will resume qmu, may cause qmu can't work
                          when enable ep next time [2]

[1]: when the tx fifo has some data to transmit, and
    try to stop qmu (stop ep) meanwhile resume qmu (queue tx request),
    it may cause stop qmu timeout, then can be fixed by flushing fifo
    when stop qmu.
[2]: it resumes qmu again, shall stop qmu again.

3e679bde52 usb: fotg210-udc: Implement VBUS session 
Implement VBUS session handling for FOTG210. This is
mainly used by the UDC driver which needs to call down to
the FOTG210 core and enable/disable VBUS, as this needs to be
handled outside of the HCD and UDC drivers, by platform
specific glue code.

The Gemini has a special bit in a system register to turn
VBUS on and off so we implement this in the FOTG210 core.

02b332a063 usb: typec: maxim_contaminant: Implement check_contaminant callback 
Maxim TCPC has additional ADCs and low current(1ua) current source
to measure the impedance of CC and SBU pins. When tcpm invokes
the check_contaminant callback, Maxim TCPC measures the impedance
of the CC & SBU pins and when the impedance measured is less than
1MOhm, it is assumed that USB-C port is contaminated. CC comparators
are also checked to differentiate between presence of sink and
contaminant. Once USB-C is deemed to be contaminated, MAXIM TCPC
has additional hardware to disable normal DRP toggling cycle and
enable 1ua on CC pins once every 2.4secs/4.8secs. Maxim TCPC
interrupts AP once the impedance on the CC pin is above the
1MOhm threshold. The Maxim tcpc driver then signals TCPM_PORT_CLEAN
to restart toggling.

Renaming tcpci_maxim.c to tcpci_maxim_core.c and moving reg read/write
helper functions to the tcpci_maxim.h header file.

599f008c25 usb: typec: tcpm: Add callbacks to mitigate wakeups due to contaminant 
On some of the TCPC implementations, when the Type-C port is exposed
to contaminants, such as water, TCPC stops toggling while reporting OPEN
either by the time TCPM reads CC pin status or during CC debounce
window. This causes TCPM to be stuck in TOGGLING state. If TCPM is made
to restart toggling, the behavior recurs causing redundant CPU wakeups
till the USB-C port is free of contaminant.

To mitigate redundant TCPM wakeups, TCPCs which do have the needed hardware
can implement the check_contaminant callback which is invoked by TCPM
to evaluate for presence of contaminant. Lower level TCPC driver can
restart toggling through TCPM_PORT_CLEAN event when the driver detects
that USB-C port is free of contaminant. check_contaminant callback also
passes the disconnect_while_debounce flag which when true denotes that
the CC pins transitioned to OPEN state during the CC debounce window.

30374434ed USB: fix memory leak with using debugfs_lookup() 
When calling debugfs_lookup() the result must have dput() called on it,
otherwise the memory will leak over time.  To make things simpler, just
call debugfs_lookup_and_remove() instead which handles all of the logic at
once.
