2011-11-10backlight/leds: add low threshold to pwm backlight/ledPhilippe Langlais
The intensity of the backlight/led can be varied from a range of max_brightness to zero. Though most, if not all the pwm based backlight/led devices start flickering at lower brightness value. And also for each device there exists a brightness value below which the backlight appears to be turned off though the value is not equal to zero. If the range of brightness for a device is from zero to max_brightness. A graph is plotted for brightness Vs intensity fo the pwm based backlight/led device has to be a linear graph. intensity | / | / | / |/ --------- 0 max_brightness But pratically on measuring the above we note that the intensity of backlight/led goes to zero(OFF) when the value in not zero almost nearing to zero(some x%). so the graph looks like intensity | / | / | / | | ------------ 0 x max_brightness In order to overcome this drawback knowing this x% i.e nothing but the low threshold beyond which the backlight/led is off and will have no effect, the brightness value is being offset by the low threshold value(retaining the linearity of the graph). Now the graph becomes intensity | / | / | / | / ------------- 0 max_brightness With this for each and every digit increment in the brightness from zero there is a change in the intensity of backlight/led. Devices having this behaviour can set the low threshold brightness(lth_brightness) and pass the same as platform data else can have it as zero.

Fix regression introduced by commit 5ada28bf7675 ("led-class: always implement blinking") which broke sysfs delay handling by not storing the updated value. Consequently it was only possible to set one of the delays through the sysfs interface as the other delay was automatically restored to it's default value. Reading the parameters always gave the defaults.

2011-07-08drivers/leds/leds-pca9532.c: change driver name to be uniqueWolfram Sang
This driver handles the variants pca9530-pca9533, so it chose the name "pca953x". However, there is a gpio driver which decided on the same name. As a result, those two can't be loaded at the same time. Add a subsystem prefix to make the driver name unique. Device matching will not suffer, because both are I2C drivers which match using a i2c_device_id-table which is not altered.

2011-05-25leds: support automatic start of blinking with ledtrig-timerEsben Haabendal
By setting initial values blink_delay_on and blink_delay_off in a led_classdev struct, this change starts the blinking when the led is initialized. With this patch, you can initialize blink_delay_on and blink_delay_off in led_classdev with default_trigger set to "timer", and the led will start up blinking. The current ledtrig-timer implementation ignores any initial blink_delay_on/blink_delay_off settings, and requires setting blink_delay_on/blink_delay_off (typically from userspace) before the led blinks.

2011-03-23mfd: Adopt mfd_data in 88pm860x ledHaojian Zhuang
Copy 88pm860x platform data into different mfd_data structure for led driver. So move the identification of device node from led driver to mfd driver. Signed-off-by: Haojian Zhuang <haojian.zhuang@marvell.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
2011-03-23mfd: mfd_cell is now implicitly available to mc13xxx driversAndres Salomon
The cell's platform_data is now accessed with a helper function; change clients to use that, and remove the now-unused data_size. Note that mfd-core no longer makes a copy of platform_data, but the mc13xxx-core driver creates the pdata structures on the stack. In order to get around that, the various ARM mach types that set the pdata have been changed to hold the variable in static (global) memory. Also note that __initdata references in aforementioned pdata structs have been dropped. Signed-off-by: Andres Salomon <dilinger@queued.net> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

2011-03-22leds: convert bd2802 driver to dev_pm_opsMark Brown
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. Do this move for the bs2802 driver.

2011-01-13leds: add output inversion option to backlight triggerJanusz Krzysztofik
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.

2011-01-13leds-lp5521: modify the way of setting led device nameArun Murthy
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.
