For a640/a680, we need to actually disable CX GDSC instead of
just return a enable state, the GMU oob set will timeout while
doing gmu idle check, therefor to really turn off CX GDSC
requires to set regulator mode first, and there are several
places to disable cx gdsc, move the set mode to
a6xx_cx_regulator_disable_wait.

Currently, the driver is relying on remove_requests or
ep_dequeue to giveback the requests to function driver,
but when the stop active transfer is called it will
return with error status and will bail out from remove
request without clearing the requests. At this point
we rely on ep_dequeue to clear those requests, but since
usb is disconnected, it will be in LPM which would
drive dequeue to bailout without clearing the requests.
Fix this by removing the LPM check from dequeue to
stop_active_transfer. Now if dequeue process proceeds
will check in stop_active_transfer, if dwc3 is in lpm
bail out from the process. Dequeue will further proceed
& clean up the request from cancelled list.

Sometimes IB1_BASE from register does not match with IB1 of the
ring buffer, this may happen while doing save restore of IB
during preemption. In such case, to dump IB1 in snapshot, check
for overlap between IB1_BASE and IB1 from the ring buffer and
dump IB1 in snapshot as per ring buffer's IB1 base and size.

Some USB host PCs switch the downstream port mode from
CDP to SDP if the device does not pull DP up within certain
duration (~2s).
This limits the current drawn by the device to 500mA(or 900mA)
as opposed to the possible 1.5A resulting in slow charging of
the battery.
Fix this by driving a DP pulse when there is a connect
notification from PMIC and detected the charger type as CDP.

For endpoint event registration do not depend on
num_ep, active_num_ep and pending_ep_reg variables.
Instead, create a list of registered endpoints and
notify an endpoint by iterating over the list of
registered endpoints with their corresponding
registered event. This also removes dependency on
PCIe device table and simplifies
msm_pcie_config_device_table function. Keep the
handling of upstream port I/O, memory and BME.

Decouple endpoint event registration from link suspend.
Instead of relying on pending_ep_reg and num_active_ep
create an enumerated endpoint list at the time of endpoint
enumeration and move it to suspended endpoint list up
on link suspend. If enumerated endpoint list becomes
empty allow link suspend. Move endpoint back to enumerated
list upon resume. This also removes a race where all
endpoints have not completed their enumeration and one of
the endpoints request to suspend the link.

It possible that EP gets PCI probe and tries to access EP config
space before driver could finish setting up PCIe device table.
Due to this race before driver could populate the config base
address in table, operation config call back from framework
tries to de-reference config base address which is NULL. Fix
this issue by dynamically configuring iATU with config space
address range mapping to the BDF for which config space is
requested for. This prevents access to pcie device table which
is used for static mapping for multiple device config space to
its BDF.

AER handler is directly using raw read and write APIs to access
endpoint config space. Instead, use PCI framework provided APIs
as well as the register macros to stream line all config space
reads and writes to go through PCI read and write operation.
Also, use PCI framework APIs to find the pci device using BDF
this removes the dependency on local pci device table.

AER handling requires finding the source pci device on
the bus which causes the AER. Source pci device is found
using bus, device and function number. Finding pci device
requires sleeping context because bus is walked by holding
semaphore. Hence move AER handling to threaded irq context.

In haptics pattern/fifo/brake debugfs file write operation functions,
strsep() is used iteratively to split the user-passed string into tokens
for setting parameters. However, strsep() modifies the pointer passed
and hence the same pointer cannot be used in kfree(). Fix this by
copying the pointer originally allocated by kzalloc() and use it in
kfree() as well.

Commit 3ef97296e7 ("usb: dwc3: gadget: Handle race between
remove_request & ep_dequeue") was introduced to fix the race
between remove_requests & dequeue process,but it exposes a new
issue where we see crash on ep_set_halt where the started list
gets corrupted since composite cleanup already did a free_req.
Fix this by reverting the older patch and handling the race
of remove_requests & dequeue in cleanup_cancelled_request
by iterating over the list using while loop which will insure
to access the first node from list_head.
