The LM3630 chip was revised by TI and chip name was also changed to
LM3630A. And register map, default values and initial sequences are
changed. The files, lm3630_bl.{c,h} are replaced by lm3630a_bl.{c,h} You
can find more information about LM3630A(datasheet, evm etc) at
http://www.ti.com/product/lm3630a
