2012-05-22backlight/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.

The lp5521 has autonomous operation mode without external control. Using lp5521_platform_data, various led patterns can be configurable. For supporting this feature, new functions and device attribute are added. Structure of lp5521_led_pattern: 3 channels are supported - red, green and blue. Pattern(s) of each channel and numbers of pattern(s) are defined in the pla= tform data. Pattern data are hexa codes which include pattern commands such like set pwm, wait, ramp up/down, branch and so on. Pattern mode functions: * lp5521_clear_program_memory Before running new led pattern, program memory should be cleared. * lp5521_write_program_memory Pattern data updated in the program memory via the i2c. * lp5521_get_pattern Get pattern from predefined in the platform data. * lp5521_run_led_pattern Stop current pattern or run new pattern. Transition time is required between different operation mode. Device attribute - 'led_pattern': To load specific led pattern, new device attribute is added. When the lp5521 driver is unloaded, stop current led pattern mode. Documentation updated : description about how to define the led patterns and example.

2012-03-23drivers/leds/leds-tca6507.c: cleanup error handling in tca6507_probe()Dan Carpenter
Just a small tidy-up. 1) There is a NULL dereference if the tca allocation fails. 2) The call to cancel_work_sync() isn't needed because we haven't scheduled any work. 3) The call to i2c_set_clientdata() isn't needed because the core handles that automatically if probe() fails. 4) I added some curly braces for style reasons.

2012-02-08drivers/leds/leds-lm3530.c: fix setting pltfm->als_vmaxAxel Lin
In current code, pltfm->als_vmin is set to LM3530_ALS_WINDOW_mV and pltfm->als_vmax is 0. This does not make sense. I think what we want here is setting pltfm->als_vmax to LM3530_ALS_WINDOW_mV. Both als_vmin and als_vmax local variables will be set to pltfm->als_vmin and pltfm->als_vmax by a few lines latter. Thus also remove a redundant assignment for als_vmin and als_vmax in this patch.

2012-01-13module_param: make bool parameters really bool (drivers & misc)Rusty Russell
module_param(bool) used to counter-intuitively take an int. In fddd5201 (mid-2009) we allowed bool or int/unsigned int using a messy trick. It's time to remove the int/unsigned int option. For this version it'll simply give a warning, but it'll break next kernel version. Acked-by: Mauro Carvalho Chehab <mchehab@redhat.com> Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
