+ bool "Enable driver for LP87565 PMIC regulators"
+ depends on PMIC_LP87565
+ ---help---
+ This enables implementation of driver-model regulator uclass
+ features for REGULATOR LP87565 and the family of LP87565 PMICs.
+ LP87565 series of PMICs have 4 single phase BUCKs that can also
+ be configured in multi phase modes. The driver implements
+ get/set api for value and enable.
