title: Integrated connectivity Platform Driver
|
|
|
|
description:
|
|
Integrated connectivity platform driver adds support for the Integrated WLAN
|
|
that runs on Q6 based platforms. WLAN FW on these architecture runs on Q6. This
|
|
platform driver communicates with WLAN FW over QMI, WLAN on/off messages
|
|
to FW are communicated thru this interface. This driver also listens to
|
|
WLAN PD restart notifications.
