CNSS driver controls the power on/off wlan device. because on CPE
platform the link/power status of RC<->USP may be still on when wlan
device is turning on/off, this may cause uncorrectable AER error on
DSP side, to avoid this issue DSP's downstream link should be
disabled before power on/off wlan device, and re-enabled after wlan
power on, and also wait for link training of DSP<->WLAN to complete.
To be compitable with non PCIE switch platform, add a new config
CONFIG_PCIE_SWITCH_SUPPORT to enable/disable this function

When WPSS crashes, remoteproc module sets notif->crashed to 1 in case
of BEFORE_SHUTDOWN, whereas, in case of AFTER_SHUTDOWN, remoteproc
module sets notif->crashed to 0.
To avoid MSA0 ramdump collection on graceful shutdown case, save
notif->crashed flag to determine WPSS crash and collect MSA0 ramdump
only when WPSS crashes.

During cnss unload or error quit, cnss_dms_deinit() is called to
perform dms client deinit. When dms sever quit, modem also send event
to cnss to schedule dms client restart with dms_del_server(). The two
processes are asynchronous so qmi_handle_release() may be entered
twice and cause qmi->sock to be used after free.
To avoid this race condition, call cnss_cancel_dms_work() before
cnss_dms_deinit() to guarantee the two processes not run concurrently.

Since PCIE Genoa has separate wlan fw patch for
mission mode(amss.bin) and ftm mode(genoaftm.bin),
but cnss2 platform driver always try to load amss.bin,
which is not feasible. So add this new interface for
cnss2 to get correct driver mode and update the fw
patch name.

On some platforms, those with all of icnss, cnss
and the corresponding wlan drivers being present, but
only one dt node for wlan device, we only need one
platform driver which is compatible with the dt node.
To achieve this, return '-ENODEV' on icnss driver loading
if there is no matching dt node, just as cnss2 does.
This change can also fix the issue as below:
Background: icnss2 returns '-EAGAIN' when wlan driver
register request comes too early, to trigger the retry
mechanism in wlan driver.
Considering a device with drivers and dt node as
mentioned upon, and a wlan driver is trying to
register itself in icnss2 driver. But it will
definitely fail because icnss2 has not been probed
(due to no compatible dt node) and retry for up to
50 times with a 100ms interval due to the return
value '-EAGAIN'. This delays android bootup.
With this fix applied, wlan driver loading will fail
before registering itself to platform driver because
it depends on icnss2 that failed to load.

Sometimes wlan driver loading comes very early, icnss2
driver is not ready at that point and returns '-ENODEV',
which results in wlan failure.
To fix it, icnss2 returns '-EAGAIN' in such case to

It's possible that the 'rproc name' doesn't contain
'wpss' when 'rproc_restart_level_notifier()' gets called,
there are two issues in such case:
1. The fixed length 'ICNSS_RPROC_LEN(100)' for strnstr()
is too long for some cases, which may leads to
'slab-out-of-bounds' issue in strnstr().
To fix it, pass strlen of the rproc name instead.
2. It returns without freeing memory for the event data
and results in memory leak.
To fix it, allocate memory for the event only when
the notification is for 'wpss'.

driver is not ready. During second chip probing, first chip may retry
to probe. So, second chip may set/get plat_env[0], first chip may

If sencond chip not attached, plat_env[0] will be cleaned. When
cnss_pci_probe() is called by first chip, cnss_get_plat_priv_by_rc_num()
will call plat_env[0]. However it is already NULL.
