config DM_PMIC bool "Enable Driver Model for PMIC drivers (UCLASS_PMIC)" depends on DM ---help--- This config enables the driver-model PMIC support. UCLASS_PMIC - designed to provide an I/O interface for PMIC devices. For the multi-function PMIC devices, this can be used as parent I/O device for each IC's interface. Then, each children uses its parent for read/write. For detailed description, please refer to the files: - 'drivers/power/pmic/pmic-uclass.c' - 'include/power/pmic.h' config PMIC_CHILDREN bool "Allow child devices for PMICs" depends on DM_PMIC default y ---help--- This allows PMICs to support child devices (such as regulators) in SPL. This adds quite a bit of code so if you are not using this feature you can turn it off. Most likely you should turn it on for U-Boot proper. config SPL_PMIC_CHILDREN bool "Allow child devices for PMICs in SPL" depends on DM_PMIC default y ---help--- This allows PMICs to support child devices (such as regulators) in SPL. This adds quite a bit of code so if you are not using this feature you can turn it off. In this case you may need a 'back door' to call your regulator code (e.g. see rk808.c for direct functions for use in SPL). config PMIC_ACT8846 bool "Enable support for the active-semi 8846 PMIC" depends on DM_PMIC && DM_I2C ---help--- This PMIC includes 4 DC/DC step-down buck regulators and 8 low-dropout regulators (LDOs). It also provides some GPIO, reset and battery functions. It uses an I2C interface and is designed for use with tablets and smartphones. config DM_PMIC_PFUZE100 bool "Enable Driver Model for PMIC PFUZE100" depends on DM_PMIC ---help--- This config enables implementation of driver-model pmic uclass features for PMIC PFUZE100. The driver implements read/write operations. config DM_PMIC_MAX77686 bool "Enable Driver Model for PMIC MAX77686" depends on DM_PMIC ---help--- This config enables implementation of driver-model pmic uclass features for PMIC MAX77686. The driver implements read/write operations. config PMIC_PM8916 bool "Enable Driver Model for Qualcomm PM8916 PMIC" depends on DM_PMIC ---help--- The PM8916 is a PMIC connected to one (or several) processors with SPMI bus. It has 2 slaves with several peripherals: - 18x LDO - 4x GPIO - Power and Reset buttons - Watchdog - RTC - Vibrator drivers - Others Driver binding info: doc/device-tree-bindings/pmic/pm8916.txt config PMIC_RK808 bool "Enable support for Rockchip PMIC RK808" depends on DM_PMIC ---help--- The Rockchip RK808 PMIC provides four buck DC-DC convertors, 8 LDOs, an RTC and two low Rds (resistance (drain to source)) switches. It is accessed via an I2C interface. The device is used with Rockchip SoCs. This driver implements register read/write operations. config PMIC_S2MPS11 bool "Enable Driver Model for PMIC Samsung S2MPS11" depends on DM_PMIC ---help--- The Samsung S2MPS11 PMIC provides: - 38 adjustable LDO regulators - 9 High-Efficiency Buck Converters - 1 BuckBoost Converter - RTC with two alarms - Backup battery charger - I2C Configuration Interface This driver provides access to I/O interface only. Binding info: doc/device-tree-bindings/pmic/s2mps11.txt config DM_PMIC_SANDBOX bool "Enable Driver Model for emulated Sandbox PMIC " depends on DM_PMIC ---help--- Enable the driver for Sandbox PMIC emulation. The emulated PMIC device depends on two drivers: - sandbox PMIC I/O driver - implements dm pmic operations - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission A detailed information can be found in header: '' The Sandbox PMIC info: * I/O interface: - I2C chip address: 0x40 - first register address: 0x0 - register count: 0x10 * Adjustable outputs: - 2x LDO - 2x BUCK - Each, with a different operating conditions (header). * Reset values: - set by i2c emul driver's probe() (defaults in header) Driver binding info: doc/device-tree-bindings/pmic/sandbox.txt config PMIC_S5M8767 bool "Enable Driver Model for the Samsung S5M8767 PMIC" depends on DM_PMIC ---help--- The S5M8767 PMIC provides a large array of LDOs and BUCKs for use as a SoC power controller. It also provides 32KHz clock outputs. This driver provides basic register access and sets up the attached regulators if regulator support is enabled. config PMIC_TPS65090 bool "Enable driver for Texas Instruments TPS65090 PMIC" depends on DM_PMIC ---help--- The TPS65090 is a PMIC containing several LDOs, DC to DC convertors, FETs and a battery charger. This driver provides register access only, and you can enable the regulator/charger drivers separately if required.
