Input: gpio_keys - use of_property_read_u32()

2011-09-21T05:46:32Z

Use the of_property_read_u32() helper function to retrieve u32 values from the device tree. Also do not pass the len parameter to of_get_property if it isn't checked afterwards. Signed-off-by: Tobias Klauser Signed-off-by: Dmitry Torokhov

Input: gpio_keys - return proper error code if memory allocation fails

2011-07-30T19:19:02Z

Return -ENOMEM if kzalloc fails in gpio_keys_get_devtree_pdata(). Signed-off-by: Tobias Klauser Signed-off-by: Dmitry Torokhov

Input: gpio_keys - switch to using SIMPLE_DEV_PM_OPS

2011-07-10T23:08:32Z

This reduces amount #ifdeds in the code. Signed-off-by: Dmitry Torokhov

Input: gpio_keys - add support for device-tree platform data

2011-07-10T23:08:28Z

This patch enables fetching configuration data, which is normally provided via platform_data, from the device-tree instead. If the device is configured from device-tree data, the platform_data struct is not used, and button data needs to be allocated dynamically. Big part of this patch deals with confining pdata usage to the probe function, to make this possible. Signed-off-by: David Jander Signed-off-by: Dmitry Torokhov

Input: gpio_keys - fix a memory leak

Input: gpio_keys - move to late_initcall

2011-06-27T19:44:05Z

Initialize gpio_keys driver at late_initcall level, to give it a chance to work with GPIO expanders that might not be ready yet if we initialize the driver at module_init time. This is strictly a band-aid until there is a better way to specify inter-device dependencies. Signed-off-by: David Jander Acked-by: Grant Likely Signed-off-by: Dmitry Torokhov

Input: gpio_keys - switch to using threaded IRQs

2011-06-21T21:33:34Z

Use a threaded interrupt handler in order to permit the handler to use a GPIO driver that causes things like I2C transactions being done inside the handler context. Signed-off-by: David Jander Acked-by: Grant Likely Signed-off-by: Dmitry Torokhov

Input: gpio-keys - add support for setting device name

2011-04-12T06:53:19Z

This patch allows to set a device name which helps distinguishing several gpio-keys devices. Signed-off-by: Alexander Stein Signed-off-by: Dmitry Torokhov

Input: gpio_keys - add support for EV_ABS

2011-04-12T06:53:09Z

With this patch you can setup a group of GPIOs representing a specific position on an EV_ABS axis. Signed-off-by: Alexander Stein Signed-off-by: Dmitry Torokhov

Input: gpio_keys - switch to using request_any_context_irq

2011-01-21T07:12:01Z

The driver does not require hardirq context and can work with threaded interrupts as well, so let's switch to request_any_context_irq which will select the context that is available for us. Signed-off-by: Philippe Langlais Signed-off-by: Dmitry Torokhov
