| 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() |

| 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>' |

| 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. |
