6  AXP192 PMIC
7
8  The PMIC has three DCDC converters and two LDOs (LDO1 cannot be disabled).
9  All need to be defined as children nodes.
10  For example:
11
12  i2c {
13    pmic@34 {
14      reg = <0x34>;
15      ...
16      regulators {
17        compatible = "x-powers,axp192-regulator";
18
19        DCDC1 {
20          /* all properties for DCDC1 */
21        };
22        DCDC2 {
23          /* all properties for DCDC2 */
24        };
25        DCDC3 {
26          /* all properties for DCDC3 */
27        };
28        LDOIO0 {
29          /* all properties for LDOIO0 */
30        };
31        LDO2 {
32          /* all properties for LDO2 */
33        };
34        LDO3 {
35          /* all properties for LDO3 */
36        };
37      };
38    };
39  };
