8 device for each IC's interface. Then, each children uses its parent
9 for read/write. For detailed description, please refer to the files:

14 bool "Allow child devices for PMICs"
18 This allows PMICs to support child devices (such as regulators) in
19 SPL. This adds quite a bit of code so if you are not using this
20 feature you can turn it off. Most likely you should turn it on for
23 config SPL_PMIC_CHILDREN
24 bool "Allow child devices for PMICs in SPL"
28 This allows PMICs to support child devices (such as regulators) in
29 SPL. This adds quite a bit of code so if you are not using this
