2011-05-16nvrm: move stale wait checking into the kerneltegra-11.2.6Chris Johnson
The kernel now receives wait tracking data (similar to gathers and relocs) and compares the current syncpt with the threshold value. If it's old, it gets a kernel mapping and rewrites the method data to use a kernel reserved syncpt that is always 0 (so trivially pops when seen by the HW). Bug 519650 Bug 785525 Bug 803452 Note: reset the author in this commit to fix a email addr problem and since from the latest/last cherry pick there was a reworking of the code to be compatible with different user space versions it also seemed reasonable.

2011-03-22video: pwm_backlight: Add check_fb hookRobert Morell
In systems with multiple framebuffer devices, one of the devices might be blanked while another is unblanked. In order for the backlight blanking logic to know whether to turn off the backlight for a particular framebuffer's blanking notification, it needs to be able to check if a given framebuffer device corresponds to the backlight. This plumbs the check_fb hook from core backlight through the pwm_backlight helper to allow platform code to plug in a check_fb hook.

2011-03-22backlight: add low threshold to pwm backlightArun Murthy
The intensity of the backlight can be varied from a range of max_brightness to zero. Though most, if not all the pwm based backlight 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 for the pwm based backlight device has to be a linear graph. intensity | / | / | / |/ --------- 0 max_brightness But pratically on measuring the above we note that the intensity of backlight 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 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. 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.
