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. allOf: - $ref: ../input/input.yaml properties: compatible: enum: - actions,atc2603c - actions,atc2609a reg: maxItems: 1 interrupts: maxItems: 1 reset-time-sec: description: | Duration in seconds which the key should be kept pressed for device to reset automatically.
