Otherwise it looks good. Driver is loaded and device is detected

Do you know where I can measure result from changing brightness
sysfs entry. I am using 8074 dragonboard?

Does the backlight turn on? From what I can tell it controls the
backlight, but it may be that nothings getting displayed so it won't be
noticeable.

Yes, I can not see visual changes. That is why I have asked where
I could hook the probe and measure current change or wherever.
BL_WLEDx signals go out from J2, but somehow I was unable to 
locate it on the board, will try to look harder :-)
