ARM: S5PV210: Set 1000ns as PWM backlight period on SMDKV210
The SMDK board uses LT3591 as backlight LED driver of LTE480WV LCD.
According to the LT3591 datasheet, the switching frequency should
be 1MHz. So, PWM period is calculated by following formula:
PWM period = 1/switching frequency
= 1/1MHz
= 1000ns
Thus, the PWM backlight period should be 1000ns.
