Re: [PATCH] pwm-backlight: add "max-brightness" property

Specifying each individual brightness value via the "brightness-levels"
property can be a pain if we want to use a large continuous range of
brightness values.  Add the property "max-brightness", which can be
given in place of "brightness-levels", that specifies that all values
between 0 and the given value can be used.

What about the non-linear nature of PWM duty cycle <-> (perceived)
brightness level? That's why the values are typically enumerated. I
guess if you use this new property, you'd use a value of say 16;
exposing levels 0..255 to a user is probably more than they want?
