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_dev() 17 otherwise. Detailed information can be found in the header file. 18 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>' 107 Binding info: 'doc/device-tree-bindings/pmic/max77686.txt' 108 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. 118
