+description: |
+ 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 and 9 LDO regulators.
+ ATC2609A includes 5 programmable DC-DC converters and 10 LDO regulators.
