Remove max_data_size sysfs entry. Otherwise is possible to have a buffer overrun if its value is increased after the device is open. Signed-off-by: NCarlos Chinea <carlos.chinea@nokia.com> Acked-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: NLinus Walleij <linus.walleij@linaro.org>

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 controllers and ports do not belong to the HSI bus. Those devices are not supposed to have a driver attached to them. Signed-off-by: NCarlos Chinea <carlos.chinea@nokia.com> Acked-by: NGreg Kroah-Hartman <gregkh@linuxfoundation.org> Acked-by: NLinus Walleij <linus.walleij@linaro.org>

Use the proper release mechanism for hsi_controller and hsi_ports structures. Free the structures through their associated device release callbacks.

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.
