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

Now work, but what flag i have to enable to leave 5v usb otg ON?
uboot switch ON Usb Otg voltage but kernel switch off during boot (no usb
devices work).
In order for otg to work you must load a gadget driver, e.g. do:
insmod libcomposite.ko
insmod u_serial.ko
insmod usb_f_acm.ko
insmod g_serial.ko
