ipa post init is accessed from user space
context from ops structure.
While user space program triggered post init
there could be a chance, where the
user space context may get killed at any time,
due to which the memory allocation in post init
gets failed and in turn which clean up the
IPA driver.
Because the memory allocation of the
sigkill pending process will fail.
Make changes in ops structure write func-pointer to
queue a work instead of directly invoking post init.
So that ipa post init will execute in workqueue context.

When driver calls ops_bus_request with high bandwidth requirement,
affinity of wil6210 interrupt is set to first big core. However this
setting is not cleared when driver lowers bandwidth requirement.
This causes WARN_ON_ONCE(desc->affinity_hint) upon wil6210 rmmod.
Fix this by clearing affinity hint upon low bandwidth request.

In order to preserve the connection in suspend/resume flow,
wil6210 host allows going to PCIe D3hot state in suspend,
instead of performing a full wil6210 device reset. This
requires the platform ability to initiate wakeup in case of
RX data. To check that, a new platform API is added.
In addition, add cfg80211 suspend/resume callbacks
implementation.

if there is an open aggregation frame. This handling is applied
to USB and MHI channels. This commit applies this handling to

Stopping a PROD channel might result in a timeout because the
channel is not empty, or IPA is busy. Whether or not to retry
a stop operation is determined by channel owner.
This change removes the common retry logic of retrying to stop
a PROD channel and adds a retry only for the scenario it is
actually needed.

There's no need to check whether the device has been connected
when disconnect it, for we'll always do disconnect after the device
has been connected. Even if we do disconnect incorrectly, it'll not
affect. Now we have both ASYNC_AUDIO/VIDEO flag and SYNC_AUDIO/
VIDEO flag. Sometimes SYNC flag would be set when device is connected,
while ASYNC flag is set when disconnect, the two flags are not match.
If we check here, that would return false. So we could remove the flags.
