LM3556 : The LM3556 is a 4 MHz fixed-frequency synchronous boost converter plus 1.5A constant current driver for a high-current white LED. Datasheet: www.national.com/ds/LM/LM3556.pdf Tested on OMAP4430 (bryan.wu@canonical.com: use module_i2c_driver() rather than lm3556_init/lm3556_exit for code simplicity; fixed some typo pointed out by Rob Landley) Signed-off-by: G.Shark Jeong <gshark.jeong@gmail.com> Reviewed-by: Axel Lin <axel.lin@gmail.com> Reviewed-by: Kim, Milo <Milo.Kim@ti.com> Acked-by: Rob Landley <rob@landley.net> Signed-off-by: Bryan Wu <bryan.wu@canonical.com>
