TX FSM reset command generates TX_RESET_DONE & TX_DMA_DONE interrupt bits.
Upon receiving TX_DMA_DONE we initiate new TX transfer for the pending
bytes present in tty uart circular buffer. That leaves TX sequencer active
after reset sequence. That can result into all kinds of SMMU crash where
client initiates new TX DMA transfer without knowing that we have already
a transfer queued. This is unexpected behaviour because we expect TX
sequencer and DMA engine to go IDLE after reset.
To fix above scenario, don't handle TX_DMA_DONE upon reciving
TX_RESET_DONE.
Also, add IPC logs to get_mctrl function to get the IOS status.

Some customers are using UART node in UFFI for console and using
the same node for HSUART in kernel but not as console. In this
scenario there is a possibility for null pointer access
with handle_rx while trying to stop secondary sequencer.
This change will move handle_rx initialization from port_startup to
probe function. This will help to avoid null pointer access issues.

preempt/irq disable events tracks and prints 4 callers (3 actual callers
and current trace event caller), who disables irqs and preemption for
longer duration. It may not be sufficient for all scenarios, so extend
these events to track 5 callers and exclude current trace event caller.

Add Trusted touch support to lahaina MTP
Touchscreen driver. This feature enables driver to
operate in trusted touch mode in trusted virtual machine(TVM).
The primary virtual machine(PVM) lends resources such
as IO memory and touch irq to TVM prior to trusted touch
is initiated and reclaims those resources back after trusted
touch usecase finishes.The resource requirements of TVM
such as clock, regulators etc are taken care by PVM.

Upstream commit aa8b37baac ("FROMLIST: sched/fair: Use wake_q
length as a hint for wake_wide") that is being carried in msm-5.4
kernel caused CRC checks failures when GKI boot image is used for
verification as the commit adds extra argument to select_task_rq().
Fix this issue by wrapping extra argument under CONFIG_SCHED_WALT.

When del client and bye command packets are sent out, if there
is an error in sending, continue with the loop to send to the
rest of the clients. The current implementation bails out when
the send fails. This is causing dropping of these packets to
the rest of the clients.

When adreno_reset fails, BUG_ON gets triggered to collect ram dump.
Do not clear dispatcher fault bits in such case to get correct fault
information from ram dump. Clear dispatcher fault when adreno_reset

Also, fix stackoverflow issue seen after propagating above changes.
Console TX is getting stuck in recursive call and leading to
stackoverflow issue.
Steps that leads to bad recursion call:
1) msm_geni_serial_handle_tx calls for stop_tx if all the data are sent and
acknowledged.
2) stop_tx issue cancel command if the main sequencer is still
active.
3) As part of cancel command execution msm_geni_serial_handle_tx is called
again that takes us to step 1 and goes in a loop.
To fix above scenario remove the stop_tx call from geni_serial_handle_tx
because if the data is transmited and acknowledged main sequencer should
automatically go to inactive state.
Ideally we should never enter into this situation the first place because
after receiving CMD_DONE we expect that sequencer will go IDLE/inactive.
So, probably this can be a race btw updation of CMD_DONE and GENI_STATUS
register because after adding some more IPC logs in the above code path we
are not hitting this issue. It might be adding required delay.

Upon driver unbind usb_free_all_descriptors() function frees all
speed descriptor pointers without setting them to NULL. In case
gadget speed changes (i.e from super speed plus to super speed)
after driver unbind only upto super speed descriptor pointers get
populated. Super speed plus desc still holds the stale (already
freed) pointer. As a result next composition switch results into
double free of super speed plus descriptor. Fix this issue by
setting all descriptor pointers to NULL after freeing them in
usb_free_all_descriptors(). Also clean up gsi_unbind() which is
setting up descriptor pointers to NULL already.

Currently USB top and bottom half are using same index to update
number of events posted/handled, and updating relevant time. As
top half is not guaranteed to be prevented when bottom half is
running those index based logging doesn't allow to relate information.
Also start logging bh_start_time and increase existing buffer size
from 10 to 25 to get more data of USB interrupt processing.
Also get count how many cancelled requqest being given back from
bottom half context, and log any update/start cmd failure.
