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_MAX77686 20 bool "Enable Driver Model for REGULATOR MAX77686" 21 depends on DM_REGULATOR && DM_PMIC_MAX77686 22 ---help--- 23 This config enables implementation of driver-model regulator uclass 24 features for REGULATOR MAX77686. The driver implements get/set api for: 25 value, enable and mode. 26 27config DM_REGULATOR_FIXED 28 bool "Enable Driver Model for REGULATOR Fixed value" 29 depends on DM_REGULATOR 30 ---help--- 31 This config enables implementation of driver-model regulator uclass 32 features for fixed value regulators. The driver implements get/set api 33 for enable and get only for voltage value. 34 35config DM_REGULATOR_SANDBOX 36 bool "Enable Driver Model for Sandbox PMIC regulator" 37 depends on DM_REGULATOR && DM_PMIC_SANDBOX 38 ---help--- 39 Enable the regulator driver for emulated Sandbox PMIC. 40 The emulated PMIC device depends on two drivers: 41 - sandbox PMIC I/O driver - implements dm pmic operations 42 - sandbox PMIC regulator driver - implements dm regulator operations 43 - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission 44 45 The regulator driver provides uclass operations for sandbox PMIC's 46 regulators. The driver implements get/set api for: voltage, current, 47 operation mode and enable state. 48 The driver supports LDO and BUCK regulators. 49 50 The Sandbox PMIC info: 51 * I/O interface: 52 - I2C chip address: 0x40 53 - first register address: 0x0 54 - register count: 0x10 55 * Adjustable outputs: 56 - 2x LDO 57 - 2x BUCK 58 - Each, with a different operating conditions (header). 59 * Reset values: 60 - set by i2c emul driver's probe() (defaults in header) 61 62 A detailed information can be found in header: '<power/sandbox_pmic.h>' 63 Binding info: 'doc/device-tree-bindings/pmic/max77686.txt' 64 65config REGULATOR_TPS65090 66 bool "Enable driver for TPS65090 PMIC regulators" 67 depends on PMIC_TPS65090 68 ---help--- 69 The TPS65090 provides several FETs (Field-effect Transistors, 70 effectively switches) which are supported by this driver as 71 regulators, one for each FET. The standard regulator interface is 72 supported, but it is only possible to turn the regulators on or off. 73 There is no voltage/current control. 74
