0014 ATC260x series PMICs integrates Audio Codec, Power Management, RTC, IR
0015 and GPIO controller blocks. Currently only the PM related functionalities
0016 (i.e. regulators and system power-off/reboot) for the ATC2603C and ATC2609A
0017 chip variants are supported.
0018 ATC2603C includes 3 programmable DC-DC converters, 9 programmable LDO
0019 regulators and 1 fixed LDO regulator.
0020 ATC2609A includes 5 programmable DC-DC converters and 10 programmable LDO
0021 regulators.
