* mode : Brightness control mode. PWM or register based.
* device_control : Value of DEVICE CONTROL register.
* initial_brightness : Initial value of backlight brightness.
-* pwm_data : Platform specific pwm generation functions.
+* period_ns : Platform specific PWM period value. unit is nano.
Only valid when brightness is pwm input mode.
- Functions should be implemented by PWM driver.
- - pwm_set_intensity() : set duty of PWM
- - pwm_get_intensity() : get current duty of PWM
* load_new_rom_data :
0 : use default configuration data
1 : update values of eeprom or eprom registers on loading driver
