+description: |
+ RTQ2208 is a highly integrated power converter that offers functional safety dual
+ multi-configurable synchronous buck converters and two LDOs.
+
+ Bucks support "regulator-allowed-modes" and "regulator-mode". The former defines the permitted
+ switching operation in normal mode; the latter defines the operation in suspend to RAM mode.
+
+ No matter the RTQ2208 is configured to normal or suspend to RAM mode, there are two switching
+ operation modes for all buck rails, automatic power saving mode (Auto mode) and forced continuous
+ conduction mode (FCCM).
+
+ The definition of modes is in the datasheet which is available in below link
+ and their meaning is::
+ 0 - Auto mode for power saving, which reducing the switching frequency at light load condition
+ to maintain high frequency.
+ 1 - FCCM to meet the strict voltage regulation accuracy, which keeping constant switching frequency.
+
+ Datasheet will be available soon at
+ https://www.richtek.com/assets/Products

-- reg : Specifies the I2C slave address.
-- xxx-supply: Input voltage supply regulator for ldo3 to ldo7.
- These entries are required if regulators are enabled for a device.
- An absence of these properties can cause the regulator registration to fail.
- If some of input supply is powered through battery or always-on supply then
- also it is required to have these parameters with proper node handle of always
- on power supply.
- vin3-supply: Input supply for ldo3
- vin4-supply: Input supply for ldo4
- vin5-supply: Input supply for ldo5
- vin6-supply: Input supply for ldo6

-- interrupt-parent : Specifies the reference to the interrupt controller.
-- interrupts : IRQ line information.
-- dlg,cs-gpios : Specify a valid GPIO for chip select
-
