WLAN RFA is present on another co-processor subsystem.
Any error fatal in co-processor subsystem will result in
WLAN reset.
In order to make sure that rf clock/rails are up before
accessing WLAN hardware, ICNSS platform driver needs to
register with co-processor SSR notification and wait for
POWER_UP event before starting QMI handshake.

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.

For WIN use case maximum number of memory segments requested
by FW is increased to 52 in QMI layer. Since CNSS2 driver uses
same QMI header files and message structures the same maximum
number of segment is applicable for CNSS2. It means for memory
allocation, FW can request 52 memory segments to CNSS2 via QMI
indication but local CNSS2 variable which get segment info from
indication supports maximum 32 segments.
To fix it, change CNSS2 array variable size to same as number of
maximum segment supported in QMI layer.

The reservation mode of interrupts in kernel assigns a dummy vector
when the interrupt is allocated and assigns a real vector when the
request_irq is called. The reservation mode helps to ease vector
pressure when devices with a large amount of queues/interrupts
are initialized, but only a minimal subset of those queues/interrupts
is actually used.
So on reservation mode, the msi_data may change after request_irq
is called, so reads msi_data again after mhi request_irq is called,
and then the correct msi_data is programmed into hardware components.
Without this change, spurious interrupt occurs in case of one MSI
vector.

Some platforms can't meet the number of MSI interrupt vectors that
wlan driver requires.

If CONFIG_ONE_MSI_VECTOR is not defined, wlan driver fails to load
if reuired MSI vector allocation fails. It is current behavior.
If CONFIG_ONE_MSI_VECTOR is defined, firstly it will allocate multiple
MSI vectors based on MSI config. If MSI vector allocation fails, it
fallbacks to one MSI vector automatically.

And, ROME firmware download is in qcacld driver. Not in cnss driver.
So, remove function cnss_pm_notify, and the export symbol cnss_lock_pm_sem
and cnss_release_pm_sem. Move the protection to qcacld driver. In qcacld
driver, use wakeup source to protect ROME firmware download.

CNSS prealloc maintains various prealloc pools of 8Kb, 16Kb, 32Kb
and so on, and allocates buffer from the pool for wlan driver. When
wlan driver requests to free the memory buffer then CNSS prealloc
derives slab_cache from virtual memory via page struct to identify
prealloc pool id to put memory buffer back into the pool.
In kernel 5.17, slab_cache is removed from the page struct. Add new
functions to store cache at the beginning of allocated buffer and
when wlan driver requests to free the memory then use that cache to
identify CNSS prealloc pool to put back memory.
