This set of patches adds support for the ST-Ericsson CG2900 Connectivity Combo
Controller (GPS & Bluetooth & FM : GBF).
It contains a core framework where users can register for specific channels.
The core API also allows registration of handlers for specific chips as well as
the transports supported.
The channels are also exposed to User space through character devices.
There is a BlueZ driver module included which connects BlueZ to the CG2900
Bluetooth channels.
There is also an audio driver where audio stacks can set the CG2900 internal
audio paths, e.g. routing FM to I2S and Bluetooth to PCM.
There are already changes planned for this driver that we will submit when
ready:
Currently board specific functionality is directly included through a header
file and source file (cg2900_devices.c and .h). This will be changed by using
platform driver mechanism instead.
The CG2900 core framework still has chip specific dependencies. We have plans
to remove them in order to be able to connect any connectivity chip to
the framework.

This patch adds support for the ST-Ericsson CG2900 connectivity
controller. This patch contains the framework for registering
users, chip handlers, and transports as well as the needed files
towards the mach-ux500 board.
This patch adds support for the ST-Ericsson CG2900 connectivity
controller. This patch registers into the CG2900 framework. It
handles chip startup and shutdown together with firmware download.
It also handles Bluetooth and FM flow control due to special H4
channel management.
This patch adds support for the ST-Ericsson CG2690 connectivity
controller. This patch registers into the CG2900 framework. It
handles chip startup and shutdown together with firmware download.
This patch adds support for using UART as transport for the
ST-Ericsson CG2690 connectivity controller. This patch registers
into the CG2900 framework. It handles chip enable and disable as
well baud rate settings. It also assembles received packets into
full Bluetooth, GPS, and FM packets.
This patch adds support for controlling the audio paths within the
ST-Ericsson CG2900 connectivity controller. This patch registers as
a user into the CG2900 framework for the bt_audio and fm_audio
channels. It contains an API for controlling the audio paths that
can also be reached from User space using a char device.
This patch adds support for using the ST-Ericsson CG2900 connectivity
controller as a driver for the BlueZ Bluetooth stack. This patch
registers as a driver into the BlueZ framework and, when opened by
BlueZ, it registers as user for bt_cmd, bt_acl, and bt_evt
channels.
