Here is a= slightly updated version of Chen-Yu's backlight
patches, also adding support for the backlight found on A13=20
based q8 tablets.

If i compile your dtsi with (obviously) pwm=C2=A0= 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 scr= ipt.bin),
but there is somewhere a bug in pwm or dtsi description of bac= klight.
