2014-02-27drivers/leds: delete non-required instances of include <linux/init.h>Paul Gortmaker1-1/+0
None of these files are actually using any __init type directives and hence don't need to include <linux/init.h>. Most are just a left over from __devinit and __cpuinit removal, or simply due to code getting copied from one driver to the next.

2013-06-21leds: lp5562: support the device tree featureKim, Milo1-5/+14
The LP55xx DT structure is applicable to the LP5562 device. The driver and documentation are updated. Compatible property of the DT : LP5521 and LP5223 were manufactured by National Semiconductor. LP5562 is a new device from Texas Instruments.

2013-04-01leds: lp55xx: configure the clock detectionKim, Milo1-4/+10
Now LP55xx provides automatic clock detection API, lp55xx_is_extclk_used(). The clock configuration can be done by the driver itself. (a) Concept The default value is set by each driver with clock selection. The internal clock selection bit is updated in case that the external clock is not detected or clock rate is not 32KHz. (b) Change on LP55xx platform data The clock configuration is done automatically, so no need to define 'update_config' in the platform side. Correlated information are removed in the documentations and header. (c) Definitions moved from header to driver files CONFIG register values are moved each driver, LP5521 and LP5562. Not necessary definitions are removed also. Signed-off-by: Milo(Woogyom) Kim <milo.kim@ti.com> Signed-off-by: Bryan Wu <cooloney@gmail.com>
2013-04-01leds: add new LP5562 LED driverKim, Milo1-0/+593
LP5562 can drive up to 4 channels, RGB and White. LEDs can be controlled directly via the led class control interface. LP55xx common driver LP5562 is one of LP55xx family device, so LP55xx common code are used. On the other hand, chip specific configuration is defined in the structure 'lp55xx_device_config' LED pattern data LP5562 has also internal program memory which is used for running various LED patterns. LP5562 driver supports the firmware interface and the predefined pattern data as well. LP5562 device attributes: 'led_pattern' and 'engine_mux' A 'led_pattern' is an index code which runs the predefined pattern data. And 'engine_mux' is updated with the firmware interface is activated. Detailed description has been updated in the documentation files, 'leds-lp55xx.txt' and 'leds-lp5562.txt'. Changes on the header file LP5562 configurable definitions are added. Pattern RGB data is fixed as constant value. (No side effect on other devices, LP5521 or LP5523.) (cooloney@gmail.com: remove redundant mutex_unlock().
