drivers/leds/leds-lp5521.c: change the return value

2011-10-19T11:34:02+00:00

In sscanf,execution of a %n directive does not always increment the assignment count returned, so ret value need not be 2 always.

drivers/leds/leds-lp5521.c: check if reset is successful

2011-10-19T05:33:28+00:00

make sure that the reset is successful by issuing a dummy read to R channel current register and check its default value. On some platforms, without this dummy read, any further access to {R/G/B}_EXEC will not have any impact.

backlight/leds: add low threshold to pwm backlight/led

2011-09-19T13:14:38+00:00

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.
