HSI: cmt_speech: Add cmt-speech driver

2015-03-31T20:14:04Z

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 Signed-off-by: Carlos Chinea Signed-off-by: Joni Lapilainen 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 Tested-by: Pavel Machek Signed-off-by: Sebastian Reichel

HSI: Introduce Nokia N900 modem driver

2014-05-15T22:55:42Z

The Nokia N900's modem is connected via Synchronous Serial Interface (SSI), which is a legacy version of MIPI's High-speed Synchronous Serial Interface (HSI). The handles the GPIOs for enabling and resetting the modem and instanciates ssi-protocol for data exchange. It does not yet support exchanging voice data with the modem.
