2014-05-16HSI: Add channel resource support to HSI clientsSebastian Reichel2-7/+51
Make HSI channel ids platform data, which can be provided by platform data. Signed-off-by: Sebastian Reichel <[email protected]> Tested-By: Ivaylo Dimitrov <[email protected]>
2014-05-16HSI: method to unregister clients from an hsi portSebastian Reichel1-0/+10
This exports a method to unregister all clients from an hsi port. Signed-off-by: Sebastian Reichel <[email protected]> Reviewed-by: Pavel Machek <[email protected]> Tested-By: Ivaylo Dimitrov <[email protected]>
2014-05-04HSI: hsi-char: fix driver for multiport scenariosSebastian Reichel1-1/+1
Fix return code check of alloc_chrdev_region, which returns 0 on success. Signed-off-by: Sebastian Reichel <[email protected]> Reviewed-by: Pavel Machek <[email protected]>
2013-10-16hsi: convert bus code to use dev_groupsGreg Kroah-Hartman1-4/+6
The dev_attrs field of struct bus_type is going away soon, dev_groups should be used instead. This converts the hsi code to use the correct field. Cc: Andrew Morton <[email protected]> Cc: Kees Cook <[email protected]> Signed-off-by: Greg Kroah-Hartman <[email protected]>
2013-07-03drivers: avoid format string in dev_set_nameKees Cook1-1/+1
Calling dev_set_name with a single paramter causes it to be handled as a format string. Many callers are passing potentially dynamic string content, so use "%s" in those cases to avoid any potential accidents, including wrappers like device_create*() and bdi_register().

2013-03-01hsi: fix kernel-doc warningsRandy Dunlap1-1/+1
Fix kernel-doc warnings in hsi files: Warning(include/linux/hsi/hsi.h:136): Excess struct/union/enum/typedef member 'e_handler' description in 'hsi_client' Warning(include/linux/hsi/hsi.h:136): Excess struct/union/enum/typedef member 'pclaimed' description in 'hsi_client' Warning(include/linux/hsi/hsi.h:136): Excess struct/union/enum/typedef member 'nb' description in 'hsi_client' Warning(drivers/hsi/hsi.c:434): No description found for parameter 'handler' Warning(drivers/hsi/hsi.c:434): Excess function parameter 'cb' description in 'hsi_register_port_event' Don't document "private:" fields with kernel-doc notation. If you want to leave them fully documented, that's OK, but then don't mark them as "private:".

2013-01-03Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman1-4/+4
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-04-23HSI: hsi_char: Remove max_data_size from sysfsCarlos Chinea1-1/+1
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: Carlos Chinea <[email protected]> Acked-by: Greg Kroah-Hartman <[email protected]> Acked-by: Linus Walleij <[email protected]>
2012-04-23HSI: hsi: Rework hsi_event interfaceCarlos Chinea1-47/+54
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.

2012-04-23HSI: hsi: Remove controllers and ports from the busCarlos Chinea1-19/+1
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: Carlos Chinea <[email protected]> Acked-by: Greg Kroah-Hartman <[email protected]> Acked-by: Linus Walleij <[email protected]>
2012-04-23HSI: hsi: Fix error path cleanup on client registrationCarlos Chinea1-1/+1
HSI client structure should be freed on error path after calling device_registration by dropping a reference to it. Signed-off-by: Carlos Chinea <[email protected]> Acked-by: Greg Kroah-Hartman <[email protected]> Acked-by: Linus Walleij <[email protected]>
2012-04-23HSI: hsi: Rework hsi_controller releaseCarlos Chinea1-42/+66
Use the proper release mechanism for hsi_controller and hsi_ports structures. Free the structures through their associated device release callbacks. Signed-off-by: Carlos Chinea <[email protected]> Acked-by: Greg Kroah-Hartman <[email protected]> Acked-by: Linus Walleij <[email protected]>

2012-01-05HSI: hsi: Introducing HSI frameworkCarlos Chinea5-0/+613
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. Signed-off-by: Carlos Chinea <[email protected]> Acked-by: Linus Walleij <[email protected]>
