| | | | | | | | | | | | | | | There is a move to deprecate bus-specific PM operations and move to using dev_pm_ops instead in order to reduce the amount of boilerplate code in buses and facilitiate updates to the PM core.

* leds: add output inversion option to backlight triggerJanusz Krzysztofik2011-01-13
| | | | | | | | | | | | | | | | | | | | | | Extend the LED backlight tirgger driver with an option that allows for inverting the trigger output polarity. With the invertion option provided, I (ab)use the backlight trigger for driving a LED that indicates LCD display blank condtition on my Amstrad Delta videophone. Since the machine has no dedicated power LED, it was not possible to distinguish if the display was blanked, or the machine was turned off, without touching it. The invert sysfs control is patterned after a similiar function of the GPIO trigger driver.

* leds-lp5521: modify the way of setting led device nameArun Murthy2011-01-13
| | | | | | | | | | | | | | | | | | | | | | | Currently the led device name is fetched from the device_type in I2C_BOARD_INFO which comes from the platform data. This name is in turn used to create an entry in sysfs. If there exists two or more lp5521 on a particular platform, the device_type in I2C_BOARD_INFO has to be the same, else lp5521 driver probe wont be called and if used so, results in run time warning "cannot create sysfs with same name" and hence a failure. The name that is used to create sysfs entry is to be passed by the struct led_platform_data. Hence adding an element of type const char * and change in lp5521 driver to use this name in creating the led device if present else use the name obtained by I2C_BOARD_INFO.

* led-class: always implement blinkingJohannes Berg2010-11-12
| | | | | | | | | | | | | | | | | | | | Currently, blinking LEDs can be awkward because it is not guaranteed that all LEDs implement blinking. The trigger that wants it to blink then needs to implement its own timer solution. Rather than require that, add led_blink_set() API that triggers can use. This function will attempt to use hw blinking, but if that fails implements a timer for it. To stop blinking again, brightness_set() also needs to be wrapped into API that will stop the software blink. As a result of this, the timer trigger becomes a very trivial one, and hopefully we can finally see triggers using blinking as well because it's always easy to use.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_device is just an alias for platform_device, so remove it entirely. Also replace to_of_device() with to_platform_device() and update comment blocks.

* leds: add LED driver for Network Space v2 LEDsSimon Guinot2010-07-16
| | | | | | | | | | | | | This patch add a LED class driver for the dual-GPIO LEDs found on the Network Space v2 board (and parents). This include Internet Space v2, Network Space (Max) v2 and d2 Network v2 boards. This dual-GPIO LED is wired to a CPLD and can blink in relation with the SATA activity. The driver expose this capability through a "sata" sysfs attribute. Signed-off-by: Simon Guinot <sguinot@lacie.com> Signed-off-by: Nicolas Pitre <nico@fluxnic.net>
* i2c: Remove all i2c_set_clientdata(client, NULL) in driversWolfram Sang2010-06-03
| | | | | | | | | | | | | | | | | | | | | I2C drivers can use the clientdata-pointer to point to private data. As I2C devices are not really unregistered, but merely detached from their driver, it used to be the drivers obligation to clear this pointer during remove() or a failed probe(). As a couple of drivers forgot to do this, it was agreed that it was cleaner if the i2c-core does this clearance when appropriate, as there is no guarantee for the lifetime of the clientdata-pointer after remove() anyhow. This feature was added to the core with commit e4a7b9b04de15f6b63da5ccdd373ffa3057a3681 to fix the faulty drivers. As there is no need anymore to clear the clientdata-pointer, remove all current occurrences in the drivers to simplify the code and prevent confusion.

* leds: leds-ss4200: fix led_classdev_unregister twice in error handlingAxel Lin2010-05-26
| | | | | | | | | | | | | In current implementation, if device_create_file failed in register_nasgpio_led, led_classdev_unregister will be executed twice. ( in register_nasgpio_led it calls led_classdev_unregister before return and in nas_gpio_init out_err ) This patch fixes it by only unregistering those that were successfully registered in out_err.

* leds: leds-gpio: Change blink_set callback to be able to turn off blinkingBenjamin Herrenschmidt2010-05-26
| | | | | | | | | | | | | | | | | | | The leds-gpio blink_set() callback follows the same prototype as the main leds subsystem blink_set() one. The problem is that to stop blink, normally, a leds driver does it in the brightness_set() callback when asked to set a new fixed value. However, with leds-gpio, the platform has no hook to do so, as this later callback results in a standard GPIO manipulation. This changes the leds-gpio specific callback to take a new argument that indicates whether the LED should be blinking or not and in what state it should be set if not. We also update the dns323 platform which seems to be the only user of this so far.
