ATC260x series PMICs integrates Audio Codec, Power Management, RTC, IR
and GPIO controller blocks. Currently only the PM related functionalities
(i.e. regulators and system power-off/reboot) for the ATC2603C and ATC2609A
chip variants are supported.
ATC2603C includes 3 programmable DC-DC converters, 9 programmable LDO
regulators and 1 fixed LDO regulator.
ATC2609A includes 5 programmable DC-DC converters and 10 programmable LDO
regulators.
