Pass wowlan configuration data as parameter in the rdev
suspend. The userspace wlan utility (iw, wpa_supplicant etc.)
configured the wow pattern and event through nl80211 cmd.
During the wlan system suspend the wlan device configured the
wakeup source and event as per the configuration data passed
by the wlan utility to wkae up the device from the sleep state
on wow pattern or event match.

During the WLAN WOWLAN mode the default listen interval needs
to be configured for each vdev to receive and process the WLAN
WOW pattern match found by the WLAN firmware.
Improper listen interval configuration for the vdev leads to WOW
pattern match missing by the WLAN module and a result WLAN module
failed to wakeup the target as per the WOW pattern configured
during WOWLAN suspend method.

sequence for both rddm and fw download are initialized to be 0.
They are incremented by 1 in bhi_probe() and upon real transfer
takes place.
Issue is in SSR case, sequence is incrementing in a way like 1,
3, 5 and etc as observed. The increment in bhi_probe() seems
unnecessay as there's no real transfer.
Fix is to initialize sequence to 1 and increment by 1 when real
transfer takes place in bhi_bhie_transfer().

As per the hardware programming sequence, HDCP authentication
process must start after turning ON the timing engine and the
authentication process should be stopped before turning OFF
the timing engine.
Implement this sequence during the HDMI turn OFF sequence.
Also, make sure to wait for one frame before disabling the DDC
while turning OFF the HDCP. This is required to make sure we
receive the HDCP encryption disabled interrupt before disabling
the HW.

When SSR happending during WLAN interface up, a deadlock will happen
in many places where it waits for FW response. When wlan module starts,
it will hold a rtnl_lock and wait for FW response. If SSR happened at
this point, it will send ssr notification to all the registed modules
one by one. It will send notification to IPA first, which will also
tried to get a hold of rtnl_lock. Since ssr notification is synchronized,
IPA won't be able to return because of failing to acquire the lock and
wlan driver won't release the rtnl_lock until it timeout and crash.
Only graceful to avoid this deadlock is to get early modem
crash notification from platform via a path which does not acquire
RTNL lock and this way once driver has received early crash
notification it can reject interface up.
Modem notification comes to icnss before IPA, hence send
early crash notification in modem SSR handler so that wlan driver
can release RTNL lock as soon as possible.

Currently when pd is disabled, we do not allow hvdcp. To fix that
once hvdcp timeout happens and if pd is disabled, force a pd_active
= 0. This will cause us to run legacy workaround and rerun apsd if
the charger was detected as hvdcp.
Importantly, once legacy bit workaround is run, wait 400mS for
typeC to debounce. Currently we wait for 100mS only and that
causes a removal detection since the CC lines are not settled within
100mS.
Also it may take up to 650mS for the vbus to drop once CC lines are
floated during the workaround. The current wait is just 500mS,
bump it up to a 1 second.
