OK nvm. I was able to change it by doing the following:
In file:
/dm3730logic_gingerbread/kernel/arch/arm/mach-omap2/board-omap3logic-display.c
I modified the following function:
dm3730_torpedo_bl_set_intensity(int level)
In the function there are 2 spots where 0xFFFF0000 shows up in the existing code:
omap_dm_timer_set_load(intensity_timer, 1, 0xFFFF0000);
AND
omap_dm_timer_set_match(intensity_timer, 1,
(0xffff0000) | (level<<8));
Change the 0xFFFF0000 to something bigger, i.e. 0xFFFFF800 will give you roughly 6Khz.
And change level << 8 to level << 3 depending on how much you shifted. For instance, 0xFFFFF800 is a 5 left shift of the original 0xFFFF0000, I would shift the level only 3 right this time.
Hope this helps other who need to increase the LCD_PWM line.
