My name is stamped into maintainership for a big slew of DT bindings. Now that it is changing, switch it over to my kernel.org mail address, which will hopefully be stable for the rest of my life.

The Kinetic Technologies KTD253 and KTD259 are white LED backlights
|
|
controlled by a single GPIO line. If you just turn on the backlight
|
|
it goes to maximum backlight then you can set the level of backlight
|
|
using pulses on the enable wire. This is sometimes referred to as
|
|
"expresswire".
