* leds: Drop owner assignment from i2c_driverKrzysztof Kozlowski2015-08-281-1/+0
| | | | | | | | i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Jacek Anaszewski <j.anaszewski@samsung.com>
* leds: lm355x: fix attribute-creation raceJohan Hovold2014-06-261-12/+9
| | | | | | | | | | | | Use the attribute groups of the led-class to create the indicator-LED attributes during probe in order to avoid racing with userspace. Note that the comment about the pattern attribute only being for LM3554 was incorrect and did not match the code (the original leds-lm3556 driver had the attribute before LM3554 support was added).

(Camera driver) (LED trigger for camera) (LED driver) Turn on the flash ...> ledtrig_flash_ctrl(true) ...> LM355x or LM3642 brightness ctrl <actual driving here> Flash/torch LEDs are controlled by other driver using LED camera trigger APIs, ledtrig_flash_ctrl()/ledtrig_torch_ctrl(). Then, actual device control is activated by each LED driver such like LM355x or LM3642. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>

* leds: Add new LED driver for lm355x chipsG.Shark Jeong2012-09-111-0/+572
This driver is a general version for LM355x,lm3554 and lm3556,led chips of TI. LM3554 : The LM3554 is a 2 MHz fixed-frequency synchronous boost converter with 1.2A dual high side led drivers. Datasheet: www.ti.com/lit/ds/symlink/lm3554.pdf LM3556 : The LM3556 is a 4 MHz fixed-frequency synchronous boost converter plus 1.5A constant current driver for a high-current white LED. Datasheet: www.national.com/ds/LM/LM3556.pdf (bryan.wu@canonical.com: use flush_work() to replace flush_work_sync() which is deprecated) Signed-off-by: G.Shark Jeong <gshark.jeong@gmail.com> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
