| * leds: Add new LED driver for lm355x chipsG.Shark Jeong2012-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * leds-lp5523: use the i2c device id rather than fixed nameKim, Milo2012-09-11
| | | | | | | | | | | | | | | | | | | | LP5523 driver supports both LP5523 and LP55231. The i2c device id is one of the two - lp5523 or lp55231. So it's better to use matching i2c device id while enumerating the device and naming LED channels. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>

| | | | | | | | | | | | | | | | To support LP55231 device, the device id is added. Additionally, the i2c driver name is changed from lp5523 to lp5523x. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
| * leds-lp5523: support new LP55231 deviceKim, Milo2012-09-11
| | | | | | | | | | | | | | | | | | | | | | New TI LP55231 device has same I2C register layout as LP5523. Therefore, all of LED operations can be shared with the LP5523 driver. To support new LP55231 device explicitly, the device description is added in the configuration file.

| * leds: triggers: send uevent when changing triggersColin Cross2012-09-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some triggers create sysfs files when they are enabled. Send a uevent "change" notification whenever the trigger is changed to allow userspace processes such as udev to modify permissions on the new files. A change notification will also be sent during registration of led class devices or led triggers if the default trigger of an led class device is found.
