One of the functions of Tahvo/Betty ASIC MFD chip is a PWM output able
to drive LED with 127 levels of brightness.
On Nokia N8x0 Internet Tablet devices, this controls the LCD backlight.

Just noticed that the binding patches should be sent to Rob Herring
and devicetree list for merging. Please take a look at the MAINTAINERS
file for details and resend :)
