Enable the AXP192/AXP2101 LED driver.
|

AXP192 and AXP2101 are multi-functional integrated Power Management IC (PMIC).
|
||||
This driver is for its LED controller feature.
|
||||
This LED controller can control the lighting using a register,
|
||||
and can also light up in response to the charging status.
