Motorola CPCAP is a PMIC (power management integrated circuit) found in multiple smartphones. This driver adds support for the chip's LED controllers. This introduces support for all controllers used by the Droid 4. According to Motorola's driver (no datasheets available) there a couple of more LED controllers. I did not add support for them, since I cannot verify that they work with my modifications.
