* HSI: Introduce driver for SSI ProtocolSebastian Reichel2014-05-161-0/+42
| | | | | | | | | This adds a driver for the SSI McSAAB protocol as used in the Nokia N900. Signed-off-by: Carlos Chinea <carlos.chinea@nokia.com> Signed-off-by: Sebastian Reichel <sre@kernel.org> Tested-By: Ivaylo Dimitrov <ivo.g.dimitrov.75@gmail.com>
* HSI: Add common DT binding for HSI client devicesSebastian Reichel2014-05-161-0/+11
| | | | | | | | Implement and document generic DT bindings for HSI clients. Signed-off-by: Sebastian Reichel <sre@kernel.org> Reviewed-by: Pavel Machek <pavel@ucw.cz> Tested-By: Ivaylo Dimitrov <ivo.g.dimitrov.75@gmail.com>
* HSI: export method to (un)register clientsSebastian Reichel2014-05-161-0/+3
| | | | | | | | | | | | | Expose method for registering and unregistering HSI clients, so that client drivers can register other client drivers. This is useful for HSI drivers, which want to use the functionality of other HSI drivers. For example the N900 modem driver can load HSI drivers for mcsaab protocol and speech protocol.

* HSI: hsi: Rework hsi_event interfaceCarlos Chinea2012-04-231-11/+14
| | | | | | | | | | | | Remove custom hack and make use of the notifier chain interfaces for delivering events from the ports to their associated clients. Clients that want to receive port events need to register their callbacks using hsi_register_port_event(). The callbacks can be called in interrupt context. Use hsi_unregestier_port_event() to undo the registration.

* HSI: hsi: Introducing HSI frameworkCarlos Chinea2012-01-051-0/+410
Adds HSI framework in to the linux kernel. High Speed Synchronous Serial Interface (HSI) is a serial interface mainly used for connecting application engines (APE) with cellular modem engines (CMT) in cellular handsets. HSI provides multiplexing for up to 16 logical channels, low-latency and full duplex communication.
