   1config DM_REGULATOR
   2        bool "Enable Driver Model for REGULATOR drivers (UCLASS_REGULATOR)"
   3        depends on DM
   4        ---help---
   5        This config enables the driver model regulator support.
   6        UCLASS_REGULATOR - designed to provide a common API for basic regulator's
   7        functions, like get/set Voltage or Current value, enable state, etc...
   8        Note:
   9        When enabling this, please read the description, found in the files:
  10        - 'include/power/pmic.h'
  11        - 'include/power/regulator.h'
  12        - 'drivers/power/pmic/pmic-uclass.c'
  13        - 'drivers/power/pmic/regulator-uclass.c'
  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
  16        for this purpose if PMIC I/O driver is implemented or dm_scan_fdt_node()
  17        otherwise. Detailed information can be found in the header file.

  19config SPL_DM_REGULATOR
  20        bool "Enable regulators for SPL"
  21        depends on DM_REGULATOR
  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.
  27
  28config REGULATOR_ACT8846
  29        bool "Enable driver for ACT8846 regulator"
  30        depends on DM_REGULATOR && PMIC_ACT8846
  31        ---help---
  32        Enable support for the regulator functions of the ACT8846 PMIC. The
  33        driver implements get/set api for the various BUCKS and LDOS supported
  34        by the PMIC device. This driver is controlled by a device tree node
  35        which includes voltage limits.
  36
  37config DM_REGULATOR_PFUZE100
  38        bool "Enable Driver Model for REGULATOR PFUZE100"
  39        depends on DM_REGULATOR && DM_PMIC_PFUZE100
  40        ---help---
  41        This config enables implementation of driver-model regulator uclass
  42        features for REGULATOR PFUZE100. The driver implements get/set api for:
  43        value, enable and mode.
  44
  45config DM_REGULATOR_MAX77686
  46        bool "Enable Driver Model for REGULATOR MAX77686"
  47        depends on DM_REGULATOR && DM_PMIC_MAX77686
  48        ---help---
  49        This config enables implementation of driver-model regulator uclass
  50        features for REGULATOR MAX77686. The driver implements get/set api for:
  51        value, enable and mode.
  52
  53config DM_REGULATOR_FIXED
  54        bool "Enable Driver Model for REGULATOR Fixed value"
  55        depends on DM_REGULATOR
  56        ---help---
  57        This config enables implementation of driver-model regulator uclass
  58        features for fixed value regulators. The driver implements get/set api
  59        for enable and get only for voltage value.
  60
  61config REGULATOR_RK808
  62        bool "Enable driver for RK808 regulators"
  63        depends on DM_REGULATOR && PMIC_RK808
  64        ---help---
  65        Enable support for the regulator functions of the RK808 PMIC. The
  66        driver implements get/set api for the various BUCKS and LDOs supported
  67        by the PMIC device. This driver is controlled by a device tree node
  68        which includes voltage limits.
  69
  70config REGULATOR_S5M8767
  71        bool "Enable support for S5M8767 regulator"
  72        depends on DM_REGULATOR && PMIC_S5M8767
  73        ---help---
  74        This enables the regulator features of the S5M8767, allowing voltages
  75        to be set, etc. The driver is not fully complete but supports most
  76        common requirements, including all LDOs and BUCKs. This allows many
  77        supplies to be set automatically using the device tree values.
  78
  79config DM_REGULATOR_SANDBOX
  80        bool "Enable Driver Model for Sandbox PMIC regulator"
  81        depends on DM_REGULATOR && DM_PMIC_SANDBOX
  82        ---help---
  83        Enable the regulator driver for emulated Sandbox PMIC.
  84        The emulated PMIC device depends on two drivers:
  85        - sandbox PMIC I/O driver - implements dm pmic operations
  86        - sandbox PMIC regulator driver - implements dm regulator operations
  87        - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
  88
  89        The regulator driver provides uclass operations for sandbox PMIC's
  90        regulators. The driver implements get/set api for: voltage, current,
  91        operation mode and enable state.
  92        The driver supports LDO and BUCK regulators.
  93
  94        The Sandbox PMIC info:
  95        * I/O interface:
  96          - I2C chip address:       0x40
  97          - first register address: 0x0
  98          - register count:         0x10
  99        * Adjustable outputs:
 100          - 2x LDO
 101          - 2x BUCK
 102          - Each, with a different operating conditions (header).
 103        * Reset values:
 104          - set by i2c emul driver's probe() (defaults in header)
 105
 106        A detailed information can be found in header: '<power/sandbox_pmic.h>'

 109config REGULATOR_TPS65090
 110        bool "Enable driver for TPS65090 PMIC regulators"
 111        depends on PMIC_TPS65090
 112        ---help---
 113        The TPS65090 provides several FETs (Field-effect Transistors,
 114        effectively switches) which are supported by this driver as
 115        regulators, one for each FET. The standard regulator interface is
 116        supported, but it is only possible to turn the regulators on or off.
 117        There is no voltage/current control.
