14 It's important to call the device_bind() with the proper node offset,
15 when binding the regulator devices. The pmic_bind_childs() can be used

22 ---help---
23 Regulators are seldom needed in SPL. Even if they are accessed, some
24 code space can be saved by accessing the PMIC registers directly.
25 Enable this option if you need regulators in SPL and can cope with
26 the extra code size.

116 The regulator driver provides uclass operations for sandbox PMIC's
117 regulators. The driver implements get/set api for: voltage, current,
118 operation mode and enable state.
119 The driver supports LDO and BUCK regulators.
