Here is a slightly updated version of Chen-Yu's backlight

If i compile your dtsi with (obviously) pwm support enable , backlight
switch off after kernel start,
if i disable pwm in menuconfig,it stay on, all seem correct (pwm on PB2 in
original script.bin),
but there is somewhere a bug in pwm or dtsi description of backlight.
No there is not, if you enable the pwm driver you must also enable
the backlight-pwm driver / add CONFIG_BACKLIGHT_PWM=y to your .config
(and make sure it stays that way after a "make oldconfig").
