This patch adds the driver for the LM3646, dual LED Flash driver.
The LM3646 has two 1.5A sync. boost converter with dual white current source.
It is controlled via an I2C compatible interface.
Each flash brightness, torch brightness and enable/disable can be controlled.

The demodulator can get in a state in ATSC mode where just
