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