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. 18 19config DM_REGULATOR_PFUZE100 20 bool "Enable Driver Model for REGULATOR PFUZE100" 21 depends on DM_REGULATOR && DM_PMIC_PFUZE100 22 ---help--- 23 This config enables implementation of driver-model regulator uclass 24 features for REGULATOR PFUZE100. The driver implements get/set api for: 25 value, enable and mode. 26 27config DM_REGULATOR_MAX77686 28 bool "Enable Driver Model for REGULATOR MAX77686" 29 depends on DM_REGULATOR && DM_PMIC_MAX77686 30 ---help--- 31 This config enables implementation of driver-model regulator uclass 32 features for REGULATOR MAX77686. The driver implements get/set api for: 33 value, enable and mode. 34 35config DM_REGULATOR_FIXED 36 bool "Enable Driver Model for REGULATOR Fixed value" 37 depends on DM_REGULATOR 38 ---help--- 39 This config enables implementation of driver-model regulator uclass 40 features for fixed value regulators. The driver implements get/set api 41 for enable and get only for voltage value. 42 43config REGULATOR_S5M8767 44 bool "Enable support for S5M8767 regulator" 45 depends on DM_REGULATOR && PMIC_S5M8767 46 ---help--- 47 This enables the regulator features of the S5M8767, allowing voltages 48 to be set, etc. The driver is not fully complete but supports most 49 common requirements, including all LDOs and BUCKs. This allows many 50 supplies to be set automatically using the device tree values. 51 52config DM_REGULATOR_SANDBOX 53 bool "Enable Driver Model for Sandbox PMIC regulator" 54 depends on DM_REGULATOR && DM_PMIC_SANDBOX 55 ---help--- 56 Enable the regulator driver for emulated Sandbox PMIC. 57 The emulated PMIC device depends on two drivers: 58 - sandbox PMIC I/O driver - implements dm pmic operations 59 - sandbox PMIC regulator driver - implements dm regulator operations 60 - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission 61 62 The regulator driver provides uclass operations for sandbox PMIC's 63 regulators. The driver implements get/set api for: voltage, current, 64 operation mode and enable state. 65 The driver supports LDO and BUCK regulators. 66 67 The Sandbox PMIC info: 68 * I/O interface: 69 - I2C chip address: 0x40 70 - first register address: 0x0 71 - register count: 0x10 72 * Adjustable outputs: 73 - 2x LDO 74 - 2x BUCK 75 - Each, with a different operating conditions (header). 76 * Reset values: 77 - set by i2c emul driver's probe() (defaults in header) 78 79 A detailed information can be found in header: '<power/sandbox_pmic.h>' 80 Binding info: 'doc/device-tree-bindings/pmic/max77686.txt' 81 82config REGULATOR_TPS65090 83 bool "Enable driver for TPS65090 PMIC regulators" 84 depends on PMIC_TPS65090 85 ---help--- 86 The TPS65090 provides several FETs (Field-effect Transistors, 87 effectively switches) which are supported by this driver as 88 regulators, one for each FET. The standard regulator interface is 89 supported, but it is only possible to turn the regulators on or off. 90 There is no voltage/current control. 91
