14 multi-configurable synchronous buck converters and two LDOs.
16 Bucks support "regulator-allowed-modes" and "regulator-mode". The former defines the permitted
17 switching operation in normal mode; the latter defines the operation in suspend to RAM mode.
19 No matter the RTQ2208 is configured to normal or suspend to RAM mode, there are two switching
20 operation modes for all buck rails, automatic power saving mode (Auto mode) and forced continuous
21 conduction mode (FCCM).
