| config DM_REGULATOR |
| bool "Enable Driver Model for REGULATOR drivers (UCLASS_REGULATOR)" |
| depends on DM |
| ---help--- |
| This config enables the driver model regulator support. |
| UCLASS_REGULATOR - designed to provide a common API for basic regulator's |
| functions, like get/set Voltage or Current value, enable state, etc... |
| Note: |
| When enabling this, please read the description, found in the files: |
| - 'include/power/pmic.h' |
| - 'include/power/regulator.h' |
| - 'drivers/power/pmic/pmic-uclass.c' |
| - 'drivers/power/pmic/regulator-uclass.c' |
| It's important to call the device_bind() with the proper node offset, |
| when binding the regulator devices. The pmic_bind_childs() can be used |
| for this purpose if PMIC I/O driver is implemented or dm_scan_fdt_node() |
| otherwise. Detailed information can be found in the header file. |

| config DM_REGULATOR_MAX77686 |
| bool "Enable Driver Model for REGULATOR MAX77686" |
| depends on DM_REGULATOR && DM_PMIC_MAX77686 |
| ---help--- |
| This config enables implementation of driver-model regulator uclass |
| features for REGULATOR MAX77686. The driver implements get/set api for: |
| value, enable and mode. |
| |
| config DM_REGULATOR_FIXED |
| bool "Enable Driver Model for REGULATOR Fixed value" |
| depends on DM_REGULATOR |
| ---help--- |
| This config enables implementation of driver-model regulator uclass |
| features for fixed value regulators. The driver implements get/set api |
| for enable and get only for voltage value. |
| |
| config REGULATOR_S5M8767 |
| bool "Enable support for S5M8767 regulator" |
| depends on DM_REGULATOR && PMIC_S5M8767 |
| ---help--- |
| This enables the regulator features of the S5M8767, allowing voltages |
| to be set, etc. The driver is not fully complete but supports most |
| common requirements, including all LDOs and BUCKs. This allows many |
| supplies to be set automatically using the device tree values. |
| |
| config DM_REGULATOR_SANDBOX |
| bool "Enable Driver Model for Sandbox PMIC regulator" |
| depends on DM_REGULATOR && DM_PMIC_SANDBOX |
| ---help--- |
| Enable the regulator driver for emulated Sandbox PMIC. |
| The emulated PMIC device depends on two drivers: |
| - sandbox PMIC I/O driver - implements dm pmic operations |
| - sandbox PMIC regulator driver - implements dm regulator operations |
| - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission |
| |
| The regulator driver provides uclass operations for sandbox PMIC's |
| regulators. The driver implements get/set api for: voltage, current, |
| operation mode and enable state. |
| The driver supports LDO and BUCK regulators. |
| |
| The Sandbox PMIC info: |
| * I/O interface: |
| - I2C chip address: 0x40 |
| - first register address: 0x0 |
| - register count: 0x10 |
| * Adjustable outputs: |
| - 2x LDO |
| - 2x BUCK |
| - Each, with a different operating conditions (header). |
| * Reset values: |
| - set by i2c emul driver's probe() (defaults in header) |
| |
| A detailed information can be found in header: '<power/sandbox_pmic.h>' |
| Binding info: 'doc/device-tree-bindings/pmic/max77686.txt' |

| config REGULATOR_TPS65090 |
| bool "Enable driver for TPS65090 PMIC regulators" |
| depends on PMIC_TPS65090 |
| ---help--- |
| The TPS65090 provides several FETs (Field-effect Transistors, |
| effectively switches) which are supported by this driver as |
| regulators, one for each FET. The standard regulator interface is |
| supported, but it is only possible to turn the regulators on or off. |
| There is no voltage/current control. |
