1config DM_PMIC 2 bool "Enable Driver Model for PMIC drivers (UCLASS_PMIC)" 3 depends on DM 4 ---help--- 5 This config enables the driver-model PMIC support. 6 UCLASS_PMIC - designed to provide an I/O interface for PMIC devices. 7 For the multi-function PMIC devices, this can be used as parent I/O 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: 10 - 'drivers/power/pmic/pmic-uclass.c' 11 - 'include/power/pmic.h' 12 13config PMIC_CHILDREN 14 bool "Allow child devices for PMICs" 15 depends on DM_PMIC 16 default y 17 ---help--- 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 21 U-Boot proper. 22 23config SPL_PMIC_CHILDREN 24 bool "Allow child devices for PMICs in SPL" 25 depends on DM_PMIC 26 default y 27 ---help--- 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 30 feature you can turn it off. In this case you may need a 'back door' 31 to call your regulator code (e.g. see rk808.c for direct functions 32 for use in SPL). 33 34config PMIC_ACT8846 35 bool "Enable support for the active-semi 8846 PMIC" 36 depends on DM_PMIC && DM_I2C 37 ---help--- 38 This PMIC includes 4 DC/DC step-down buck regulators and 8 low-dropout 39 regulators (LDOs).
