There can be scenario where CNSS driver receives
IDLE shutdown request from WLAN Host driver when
SSR/Recovery is in progress. In such case return
-EBUSY to Host driver and avoid doing IDLE Shutdown.

"__bad_udelay", since input is out of range. This change uses mdelay

this remove Host Proxy votes before sending TARGET_CAP

In icnss_pdr_notifier_cb() API, event_data gets free while

This commit updates checking for event_data->crashed before

For whatever reason, the qca6390 is not in M3 state
during PM resume phase, but still functional if do
force resume. So calling mhi_pm_resume_force()
instead of the mhi_pm_resume() to unblock PM
resume for kernel 5.15.
Reference link:

As for lower kernel version, like 5.4, it will do local
mhi pm state check in the mhi_pm_resume() instead of
target pm state check, so has no issue with qca6390.

As per Hibernate Entry (i.e. SUBSYS_BEFORE_SHUTDOWN with flag
crashed is not set) and based on low power supports it set the
state to ICNSS_LOW_POWER.
While processing the SUBSYS_AFTER_SHUTDOWN, its reset the
ICNSS_LOW_POWER state based on previous state already set
state and low power supported.
But before system freeze callback triggered,
SUBSYS_AFTER_SHUTDOWN event received to wlan and due to
which ICNSS_LOW_POWER state is clear and freeze callback failed,
thus its leads to prevent Hibernate freeze on WLAN.
This fix is to provides WLAN entered into Hibernate freeze state
by not clearing ICNSS_LOW_POWER state in SUBSYS_AFTER_SHUTDOWN.

Hibernate is a system wide power mode during which Modem
would be brought down along with DDR and the RAM contents
would be saved on the disk (suspend-to-Disk).
Modem would be do graceful shutdown in Hibernate mode,
so BEFORE_SUBSYS_DOWN notification will be received.
Based on dtsi node "is_low_power", if BEFORE_SUBSYS_DOWN
with notif->crashed bit not set is received, platform
driver will trigger an idle shutdown and set low power mode.
On AFTER_SUBSYS_DOWN notification, low power mode will be
cleared if it was set and ramdump collection will happen
only in case of crash.

Deep Sleep is a system wide low power mode during which
Modem would be brought down and DDR would be in self
refresh mode (suspend-to-RAM) thus platform driver on
receiving deep sleep indication goes to a state similar
to SSR apart from the fact that FW is not crashed but
deliberately brought down.
In msm-5.15, there are no seperate notifications used
for deep sleep, notifications used for hibernate like
BEFORE_SHUTDOWN, AFTER_SHUTDOWN, BEFORE_POWERUP and
AFTER_POWERUP are used for deep sleep also.
In this commit add only low power mode state to
icnss driver state.

framework didn't receive any notification regarding

recovery. To recover wpss from this scenerio icnss
driver tries to do self recovery of wpss subystem.

Currently, the cnss2 platform driver just can support
one wlan device attached, so do the following changes
to cover dual wlan card attach case. Firstly, delay
the second device go to pcie link suspend and power
off state to make sure it really finished the pcie
enumeration. Then pcie enumeration succeeds with
multi-devices. Secondly, supporting to write the qrtr
node instance id to PCIE register for wlan fw reading,
which can fix qmi message exchange failure if active
two Hastings devices. Thirdly, change the usage of
plat_env to support dual Hastings.

WLAN IOMMU mappings have cached attribute set whereas
ADSP IOMMU mappings do not have cached attribute set.
This is resulting in an inconsistent memory view between
ADSP SS and WLAN SS. ADSP writes to a DDR location and
WLAN HW reads from the same location but since access is
cached from WLAN side, there is a possibility of reading
incorrect values.
Fix is to use IOMMU_CACHE flag for audio smmu mappings.
