Introduces the cmt-speech driver, which implements a character device interface for transferring speech data frames over HSI/SSI. The driver is used to exchange voice/speech data between the Nokia N900/N950/N9's modem and its cpu. Signed-off-by: Kai Vehmanen <kai.vehmanen@nokia.com> Signed-off-by: Carlos Chinea <carlos.chinea@nokia.com> Signed-off-by: Joni Lapilainen <joni.lapilainen@gmail.com> Since the original driver has been written for 2.6.28 some build fixes and general cleanups have been added by me: * fix build for 4.0 kernel * replace GFP_ATOMIC with GFP_KERNEL in cs_alloc_cmds() * add sanity check for CS_SET_WAKELINE ioctl * cleanup driver initialisation * rename driver to cmt-speech to be consistent with ssi-protocol driver * move cs-protocol.h to include/uapi/linux/hsi, since it describes a userspace API * replace hardcoded channels numbers with values provided via the HSI framework (e.g. coming from DT) Acked-by: Aaro Koskinen <aaro.koskinen@iki.fi> Tested-by: Pavel Machek <pavel@ucw.cz> Signed-off-by: Sebastian Reichel <sre@kernel.org>

If you say Y here, you will enable the CMT speech protocol used
|
|
by Nokia modems. If you say M the protocol will be available as
|
|
module named cmt_speech.

This driver provides a simple character device interface for
|
|
serial communication with the cellular modem over HSI/SSI bus.
