This enables the Infineon specific emergency call state notifications so
that they show up in the traces when this happens. No logic to handle
them properly is implemented.
This patch adds support for setting up a GPRS context and then switching
it into M-RAW_IP mode. The handling of the M-RAW_IP data stream is not
yet implemented.
The Infineon modem returns more detailed information of the SIM Toolkit
proactive sessions to the modem driver. A proactive session starts with
the status response '91 xx' (proactive command pending) and ends with a
status response response of '90 00' (normal ending of command) after
Terminal Response.
So only when receiving '90 00' result, the indication that the session
has ended should be given to the core.
The current Infineon firmware overloads the AT+CFUN command with
enabling SIM Toolkit and fetching of proactive commands. It seems
to be safe to send this command in offline mode (AT+CFUN=4) and
also in online mode (AT+CFUN=1). These are the two cases where
SIM Toolkit atom would be initialized.
The XPROGRESS notifcations are now handled inside an Infineon specific
audio settings driver. So no need to do that in the the voice call
driver as well.
This is using AT+XPROGRESS=1 to enable the audio related notifications
of the modem. None of these information is currently used. This command
is only present to have these details show up in the debug logs.
The core can handle stateless drivers that do not keep clip state, in
the case of IFX we can skip the poll after ATD for finding out our CLIP
and just keep it as invalid / obtained from COLP. The core should do
the right thing.
