It is observed during some stress tests under very bad thermal conditions that wlan re-probe can fail after cnss2 probes the device for the 1st time and then powers it off. When this happens, the SW_CTRL signal doesn't go high after cnss2 toggles WLAN_EN. To avoid such issue, add support for conditional device power off so power supply will be retained for certain chipsets after cnss2 probes it for the 1st time.

CNSS2 platform driver uses QMI framework to communicate with WLAN
|
|
firmware. It sends and receives boot handshake messages to WLAN

firmware, which includes hardware and software capabilities and

configurations. It also sends WLAN on/off control message to

firmware over QMI channel.

If enabled, CNSS platform driver would do asynchronous probe.

Using asynchronous probe will allow CNSS platform driver to

reduce kernel boot time.

Runtime Power Management is supported for PCIe based WLAN Drivers.
|

The features enable cld wlan driver to suspend pcie bus when APPS

The Feature uses runtime power management framework from kernel to

track bus access clients and to synchronize the driver activity

This config flag controls the feature per target based. The feature

Conditional pcie bus suspend and device powering off for wlan after

driver probe for the first time.

With this feature enabled, pcie bus suspend and device powering off
|
|
will not take place for certain wlan chipsets after driver probing
|
|
for the first time to avoid potential subsequent failures during
|
|
device re-probe(after wlan function driver loaded) under very bad

thermal conditions.
