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.

One of the functions of Tahvo/Betty ASIC MFD chip is a voltage regulator for
Vcore output, adjustable from 1.005V to 1.475V. On Nokia N8x0 Internet Tablet
devices, this controls power to the Epson S1D13745 framebuffer IC.

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 :)
Regards,
Tony
