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
