This driver allows clients to send messages to Alway On processor
using QMP transport. Users can echo a frequency into an exposed sysfs
node to send to AOP. The driver expects the Cap frequency of DDR based
on SKU.

Consider a case where DWC3_DEPCMD_ENDTRANSFER command times out,
then controller will not receive DWC3_DEPEVT_EPCMDCMPLT event and
request queued will not be given back to the function driver from
remove_requests. Now, if a function driver(e.g mass storage)
tries to dequeue the request, gadget driver will move the request
from started_list to cancelled_list but will not giveback the
request to function driver causing it to wait forever for the
transfer to be completed. This can lead the tasks to be in hung
state causing a crash.
Fix this by giving back the request from ep_dequeue by cleaning up
the cancelled requests.

Currently the driver requires pwr_evt_irq to be compulsorily
passed from DT unless the core is dual port. Now consider a core
that does not allow SSPHY autosuspend during operational mode,
instead allowing it only as a part of dwc3_msm_ssphy_autosuspend.
As soon as autosuspend is enabled, there is a chance that
pwr_evt_irq is fired with IN_P3 bit set. Although the driver will
be marking mdwc->in_p3 in the pwr_evt_handler, it will fail to
see IN_P3 bit to be set(because it has been cleared in handler)
during the 5ms wait time in the ssphy_autosuspend function and
prepare_suspend will again set mdwc->in_p3 to 0. This leads to
failure of runtime/system suspend.
Fix this by not passing pwr_evt_irq from DT for the cores which
disable SSPHY autosuspend.

F_FS function driver allocated ffs_eps and updates ffs_ep->ep
to corresponding usb_ep during func->bind and never clears it.
On bind it also saves ffs_ep context in epfile->ep.
During func->disable, it clears only ffs_ep context in epfile->ep
and on func->unbind it frees ffs_eps memory.
ffs_epfile_io routine currently relies on ffs_ep->ep (which is
never cleared and ffs_ep could be freed on unbind) to detect any
disconnect during active IO. This can result in various issues e.g.
use after free use of ffs_ep if unbind finished before epfile_io
could resume or "stop adbd" trying to dequeue a freed USB request
when epfile_io could execute only after F_FS got disabled as
'if (ep->ep)' check would be TRUE.
Fix this by checking stored ffs_ep context against latest epfile->ep
to figure out if endpoint got disabled or changed before acquiring
spin_lock.

Since for the Genoa or the SP that doesn't need
regdb.bin for Hasting, it should happen search
regdb.bin failure issue that cause 60s timeout.
So add one compile macro CNSS_REQ_FW_DIRECT to
replace request_firmware_direct with request_
firmware for regdb.bin and only search the folder
that set by fw_path, which can avoid 60s timeout
while search file failure in the user space.

Currently power_role is accessed by set_prop and get_prop
functions of typec_power_role without any locking mechanism,
there can be a scenario where both function calls were invoked
simultaneously and power_role variable is not correctly
updated, and it leads to enumeration issues when connected to PC.
Fix it by adding locking mechanism to power_role.

already done with CNSS_MHI_POWER_OFF state set, but
cnss_suspend_pci_link() doesn't complete yet, so PCI_LINK_DOWN
won't be set, at the same time system suspend comes, it will be
failed with CNSS_MHI_SUSPEND state set checking at
cnss_pci_suspend_bus()/cnss_pci_set_mhi_state().
When mhi state is already CNSS_MHI_POWER_OFF, no need to do pci
suspend link related operation while such actions also will be done
through cnss_qca6290_shutdown()/cnss_suspend_pci_link(). Fix is to
check CNSS_MHI_POWER_OFF state in cnss_pci_suspend_bus().

Maintain a copy of the event ring read pointer in DMA coherent
memory before scheduling asynchronous DMA to update the host.
This is needed to ensure the correct read pointer value is updated
to host (for which the event DMA was done). Also schedule MSI via
IPA/EDMA to avoid potential early delivery to host (before the event
itself) when it is triggered via the PCIE controller.
