debugfs ioblob function is called by the FW logs scripts
to copy the FW logs via PCIe.
As the FW logs collection is done in parallel to the operational
11AD actions, the HALP voting can take place during 11AD reset flow
and other sensitive scenarios.
To prevent that, remove HALP voting from the ioblob function.

To enable WLAN ath10k snoc needs to send the host and target
copy engine info and driver operation mode to WLAN firmware.
The WLAN firmware configure the hardware component according
to the configure request send by ath10k snoc host driver.
Add QMI service to support this WLAN enable and disable
feature for the ath10k snoc WLAN driver.

Add support to configure the bus and wlan copy engine
component. Register event notifier to communicate with
the WLAN firmware over qmi communication interface.
Define data structure and method to process the QMI service
arrive, exit, msa ready and firmware event.
This feature adds support to maintain the SSR state machine
and ath10k core restart handler for the ath10k snoc driver.

Commit 6cd18e711d "block: destroy bdi before blockdev is
unregistered." moved bdi unregistration (at that time through
bdi_destroy()) from blk_release_queue() to blk_cleanup_queue() because
it needs to happen before blk_unregister_region() call in del_gendisk()
for MD. SCSI though will free up the device number from sd_remove()
called through a maze of callbacks from device_del() in
__scsi_remove_device() before blk_cleanup_queue() and thus similar races
as described in 6cd18e711d can happen for SCSI as well as reported by
Omar [1].
Moving bdi_unregister() to del_gendisk() works for MD and fixes the
problem for SCSI since del_gendisk() gets called from sd_remove() before
freeing the device number.
This also makes device_add_disk() (calling bdi_register_owner()) more
symmetric with del_gendisk().

Currently, when launching mdlog session, buffers are being
marked free due to which file list command response is
getting corrupted leading to file list command timeout
error. This patch fixes the issue by keeping the buffers
busy which avoids queuing of next read.

If host driver fails to probed for the first time, and SSR/PDR
get triggered, as part of PD down uevent is sent to host driver
which inturn set recovery in progress which never gets reset
and the next time on FW Ready host driver is not able
to probe successfully
To fix this add a check if driver is probed or not
before sending the uevent.

exchanged through QMI interface. This change also adds

After setting HALP ICR bit, we keep it set until HALP unvote.
Masking HALP ICR should protect the driver from hitting the HALP ICR
over and over again. However, in case there is another MISC ICR
we will read the HALP ICR and issue a completion. This can lead to
a case where HALP voting is completed immediately, as the completion
is already set.
Reinit the HALP completion before the actual vote will clear previous
completions and protect from such cases.

Some dynamic debug printouts in driver are using print_hex_dump_bytes.
However, with dynamic debug disabled, print_hex_dump_bytes outputs to
log unconditionally.
Use print_hex_dump_debug instead to prevent log pollution when dynamic
debug disabled.

There is a possibility of the NCP failing to turn on due
to an invalid (short circuit) SC event before the LCDB module
is enabled.
Force a SC re-enable to recover from this condition. Enable this
for PM660L V1.1.
Also, disable the SC handling logic for PM660L to avoid
permanently disabling the module due to the above mentioned
issue.
