Ensure the PSHardResetTimer is observed in the source case
when receiving a hard reset. Currently it is handled only
when sending a hard reset. This is achieved by moving
PE_SRC_TRANSITION_TO_DEFAULT from usbpd_set_state to usbpd_sm.

commit f2449fb61a25 ("usb: pd: Clear PD_IN_HARD_RESET in
PE_SNK_TRANSITION_TO_DEFAULT") introduced a subtle bug by
moving the clearing of the pd->hard_reset flag in sink mode
to the PE_SNK_TRANSITION_TO_DEFAULT state. This caused a
regression in which the state machine acts as if it had
received a hard reset signal and infinitely loops back there.
The cycle could only be broken if a physical disconnect happens.
Fix this by renaming the flag to hard_reset_recvd and only using
it when receiving, and not sending a hard reset.

Today IPA-USB uses disconnect sequence when USB initiates
suspend without remote wake-up, and uses suspend sequence
when USB initiates suspend with remote wake-up.
In accordance with USB-GSI driver, changing this behavior
to use suspend sequence in both of the cases. This is to
overcome some USB H/W malfunction when using disconnect
sequence in case of suspend scenario.

USB3 core expects pipe clock input for USB connection establishment
and functionality working. In case of maximum speed of USB3 core set
to HS/FS mode, it is required to disable pipe clock requirement and
instead use UTMI clock from HS PHY as clock input. Hence disable
this pipe clock requirement for the case, where maximum speed is set
to FS as well.

In case of usb bus suspend at the time of disconnect, rmnet function
suspend disables the endpoint. Same endpoint gets disabled again as
result of handling gadget driver disconnect. This generates warning
message and dumps the call stack. This may cause message flooding
as a result of multiple usb plug in/plug out. Hence replace
dev_WARN_ONCE with dev_dbg and log this event in debug buffer.

Make sure to properly clear the PD_IN_HARD_RESET property upon
reaching the SNK_Transition_to_default state to ensure that the
charger driver is notified that hard reset has completed. Move
the clearing of pd->hard_reset flag here as well for clarity.
Also clear the pd->in_pr_swap flag when initiating or receiving
hard reset signal as that should promptly abort any PR swap
operation in progress.

Support the new POWER_SUPPLY_PROP_PE_START property which
indicates when the policy engine state machine can begin.
This helps to simplify the psy_changed() routine as we can
now rely on this property to indicate that PROP_TYPEC_MODE
and PROP_TYPE are already settled. The state machine work
can now simply begin when seeing a change in TYPEC_MODE.
This replaces the previous use of PROP_PD_ALLOWED which prior
to commit 18da08334eb3 ("usb: pd: Handle PD_ALLOWED within
state machine") was intended to be a marker to start up
the policy engine but now simply indicates whether or not to
start PD comms. We can now move reading of this property to
usbpd_set_state() as it is now only needed locally in the
SNK_STARTUP handling.

Upon cable disconnect usb composition switches from midi
to default composition as a result midi function driver
frees the midi function. When cable is plugged back in
android_setup calls function setup call back for all the
function instances having non-null function pointer. This
results into access to already freed function pointer
stored in function instance. Fix this issue by setting
function instance's function pointer to NULL so that
android_setup will skip calling midi function setup upon
next cable connect.

indicating the current limit to the charger driver when
an explicit contract is established. Also set the
POWER_SUPPLY_PROP_PD_USB_SUSPEND_SUPPORTED property whenever
encountering the "USB Suspend Supported" bit in the first
PDO of a Source Capabilities message. This is an indication
to the charger that when the USB bus enters suspend state that
it should follow suspend rules according to USB 2.0/3.1 spec.

Charger may be able to detect a legacy cable connection in which
PD is not supported however the state machine still needs to
run in order to send the EXTCON_USB notification to start the
USB controller in peripheral mode (assuming type is SDP or CDP).
Move checking of PD_ALLOWED to the state machine which can be used
to determine if moving beyond PE_SNK_STARTUP is allowed or not.
The psy_changed() callback should only queue the work when either
typec_mode or pd_allowed states have changed. Also move handling
of the in_pr_swap flag to this function by absorbing the
disconnect callback and clearing the flag when CC state indicates
it is reconnected.

Set the POWER_SUPPLY_PROP_PD_IN_HARD_RESET when hard reset
has been issued and clear it when completed. This replaces
the previous use of PD_ACTIVE which is now used to indicate
assertively whether the port partner is PD capable or not.
As such, since charger driver now definitively knows, it is
also not necessary to explicitly change PROP_TYPE to USB_PD.

Support incoming VCONN Swap requests by accepting and turning
off/on VCONN.
Due to HW board limitations, if VCONN is being sourced from the
VBUS input we cannot support enabling VCONN while as a sink and
greater than 5V has been negotiated on VBUS. In that case, reject
the request. Add a device tree property that indicates whether
the board is configured for separate VCONN supply.

With PM autosleep enabled, the system may aggressively enter
and re-enter suspend in between calls to queue_work() and
when the state machine function gets executed, which may
at best result in numerous suspend/resume cycles and at
worse starve the PD state machine from even executing.
Fix this by calling pm_stay_awake() whenever the work is
queued and relinquish with pm_relax() when no further work
is to be done.

VDMs, especially structured ones, are almost always handled
as requests and responses. Hence it does not make sense to
allow more than one outgoing VDM at a time, so get rid of the
vdm_tx_queue list and simplify it to a single-issued packet.
Because port partners can only have one VDM request/response in
flight, also handle the case when a new structured request is
received before the previous response has been sent. In that
case we simply discard the queued message as it's now invalid.

As UFP since the policy engine only responds to the Discover
Identity command, all other commands are unrecognized and
therefore should be NAKed. Fix the handling as follows:
- Ensure the standard Discover Identity was sent using
SID of 0xFF00, otherwise it is invalid
- Don't NAK incoming Attention messages
- When sending a NAK, respond with the same SVID of the
initiating command, whether it was correct or not
- Enter Mode is not supported in general, but the NAK
should also be sent back with the same mode index
- Re-issue Discover SVIDs when more than 12 SVIDs are returned
- Clean up macro name prefixes from 'VDM' to 'SVDM' to
emphasize they are accessing structured VDM specific bits

Fix several issues which help address PD compliance testing:
- Soft reset should be issued instead of hard reset in cases
where an unexpected message is received.
- In source mode, send a Reject if the Request PDO object also
exceeds the advertised current capability. Fix the incorrect
bitmask in the PD_RDO_FIXED_CURR macro.
- Handle possibility of quick back-to-back RX messages by
flushing the sm worker to ensure the last message was fully
processed before overwriting the buffer.
- Discard PING messages as they are not applicable to Type-C.
- Respond to GET_SINK_CAP while in source mode, and vice
versa, respond to GET_SOURCE_CAP when in sink mode.
- Move pd->hard_reset=false to PE_SRC/SNK_TRANSITION_TO_DEFAULT
for consistency.
- Change default sink capabilities to advertise only 5V @ 900mA
since the policy engine will not automatically request higher
voltages. If userspace wants to request greater than 5V it should
also update the sink capabilities.
- Reset the protocol counters at the beginning of PE_SNK_STARTUP.

Some UDC driver doesn't allow or throw errors when USB request buffer
queued is unaligned i.e. buffer size is not equal to wMaxPacketSize or
multiple of wMaxPacketSize. Fix this issue by using 1024 bytes as MIDI
buffer size instead of 256 bytes.

Fix several issues found with PR Swap robustness.
- Change Rd->Rp as part of PE_PRS_SNK_SRC_TRANSITION_TO_OFF
instead of PE_PRS_SNK_SRC_SOURCE_ON since the latter state
is entered once the connection is re-established post-swap.
Make sure to also notify the charger to stop drawing power.
- Properly handle/ignore CC disconnect in psy_changed() which
happens during the swap operation. Similarly, don't queue the
state worker when detecting CC re-connect after becoming sink
as the transition is already handled via PD message exchange.
- Restore DRP toggling as soon as the operation is completed
in order to cycle properly after the next disconnection.
- Add tSwapSourceStart delay after becoming new source and
before sending the source capabilities messages.
- Add extra time (< tNewSrc) after enabling VBUS to allow it
to fully ramp up after becoming the new source.
- Unconditionally disable Vconn regulator during disconnect,
since it's now possible to have it on even in sink mode.

During hard reset in sink mode, move the wait for VBUS to
reconnect to the PE_SNK_TRANSITION_TO_DEFAULT state. Use
the hrtimer to wait up to the maximum expected time for
VBUS to come back, which is triggered by the CC notification
from psy_changed(). This simplifies PE_SNK_STARTUP to only be
invoked when VBUS is already present and eliminates the
PE_SNK_DISCOVERY state.
When a non-PD source is connected, as the engine attempts to
wait for source capabilities this will result in hard reset
getting attempted 3 times with the hrtimer reaching full
timeout each time (for a total of ~6s) before settling.

USB GSI endpoint related TRB ring is allocated with EP_OPS. Each USB
endpoint related TRB ring is zeroed with usb_ep_disable() operation. Hence
if USB composition switch or USB cable disconnect is performed when there
is active data transfer with USB GSI endpoint, it results into IPA GSI
accessing 0x0 address causing bus errors. Hence fix this issue by not
memsetting TRB ring with zero for USB GSI endpoint.

when xhci platform driver is removed with a usb device
connected there is a possibility of race between xhci
platform driver remove context and device disconnect hub
event work context. This results into
use after free: xhci_mem_clean() called from xhci_plat_remove()
freeing the xhci virtual device when a structure member is
being accessed by xhci_alloc_virt_device() after virtual device
allocation as part of connect hub event.
deadlock: Upon device disconnect if stop endpoint command remains
pending xhci_mem_cleanup() frees xhci virtual device which also
frees up endpoint stop_cmd_timer. udev->dev lock is held until
cancelled urb is not given back to class driver. In a different
context xhci platform remove calls usb_disconnect() on children of
root hub which tries to acquire the same udev->dev lock this results
into a dead lock condition.
Fix issues by making sure hub events are flushed before xhci is
stopped.

Currently mtp function driver is skipping function
setup call back by not populating function pointer
in function instance. Also, is_ptp flag is set
incorrectly as true for mtp instance which would
pass wrong os descriptor for mtp and ptp instance.
Allow mtp driver to send os descriptor by populating
function pointer in function instance and correctly
set the is_ptp flag to pass valid os descriptors.

'Commit c9cabb7ee02bcb0c ("usb: xhci: clean up command queue when
halting"); fixes deadlock condition when some commands are pending
at the time of usb_remove_hcd() or when controller is halted.
That change cleans up command queue if halting of controller is
successful. But, this deadlock may still be seen in case if due
to some reason halting of controller fails. To handle that scenario
as well cleanup command queue irrespective of controller halt
succeeds or fails.
