1 Linear Technology LTC3589, LTC3589-1, and LTC3589-2 8-output regulators
4 - compatible: "lltc,ltc3589", "lltc,ltc3589-1" or "lltc,ltc3589-2"
5 - reg: I2C slave address
8 - regulators: Contains eight regulator child nodes sw1, sw2, sw3, bb-out,
13 nodes for sw1, sw2, sw3, bb-out, ldo1, and ldo2 additionally need to specify
14 the resistor values of their external feedback voltage dividers:
17 - lltc,fb-voltage-divider: An array of two integers containing the resistor
22 0.3625 * (1 + R1/R2) V and 0.75 * (1 + R1/R2) V. Regulators bb-out and ldo1
24 regulator is fixed to 1.8 V on LTC3589 and to 2.8 V on LTC3589-1,2. The ldo4
26 and 3.2 V on LTC3589-1,2 in four steps. The ldo1 standby regulator can not
27 be disabled and thus should have the regulator-always-on property set.
