From 8b7cfbec052d3a0b8e8c7de24a6b5f00d340e193 Mon Sep 17 00:00:00 2001 From: G.Shark Jeong Date: Wed, 12 Sep 2012 20:05:50 +0800 Subject: leds: Add new LED driver for lm3642 chips This driver is a general version for LM642 led chip of TI. LM3642 : The LM3642 is a 4MHz fixed-frequency synchronous boost converter plus 1.5A constant current driver for a high-current white LED. The LM3642 is controlled via an I2C-compatible interface.
