1config DM_PMIC 2 bool "Enable Driver Model for PMIC drivers (UCLASS_PMIC)" 3 depends on DM 4 ---help--- 5 This config enables the driver-model PMIC support. 6 UCLASS_PMIC - designed to provide an I/O interface for PMIC devices. 7 For the multi-function PMIC devices, this can be used as parent I/O 8 device for each IC's interface. Then, each children uses its parent 9 for read/write. For detailed description, please refer to the files: 10 - 'drivers/power/pmic/pmic-uclass.c' 11 - 'include/power/pmic.h' 12 13config PMIC_CHILDREN 14 bool "Allow child devices for PMICs" 15 depends on DM_PMIC 16 default y 17 ---help--- 18 This allows PMICs to support child devices (such as regulators) in 19 SPL. This adds quite a bit of code so if you are not using this 20 feature you can turn it off. Most likely you should turn it on for 21 U-Boot proper. 22 23config SPL_PMIC_CHILDREN 24 bool "Allow child devices for PMICs in SPL" 25 depends on DM_PMIC 26 default y 27 ---help--- 28 This allows PMICs to support child devices (such as regulators) in 29 SPL. This adds quite a bit of code so if you are not using this 30 feature you can turn it off. In this case you may need a 'back door' 31 to call your regulator code (e.g. see rk808.c for direct functions 32 for use in SPL). 33 34config PMIC_ACT8846 35 bool "Enable support for the active-semi 8846 PMIC" 36 depends on DM_PMIC && DM_I2C 37 ---help--- 38 This PMIC includes 4 DC/DC step-down buck regulators and 8 low-dropout 39 regulators (LDOs). It also provides some GPIO, reset and battery 40 functions. It uses an I2C interface and is designed for use with 41 tablets and smartphones. 42 43config DM_PMIC_PFUZE100 44 bool "Enable Driver Model for PMIC PFUZE100" 45 depends on DM_PMIC 46 ---help--- 47 This config enables implementation of driver-model pmic uclass features 48 for PMIC PFUZE100. The driver implements read/write operations. 49 50config DM_PMIC_MAX77686 51 bool "Enable Driver Model for PMIC MAX77686" 52 depends on DM_PMIC 53 ---help--- 54 This config enables implementation of driver-model pmic uclass features 55 for PMIC MAX77686. The driver implements read/write operations. 56 57config PMIC_RK808 58 bool "Enable support for Rockchip PMIC RK808" 59 depends on DM_PMIC 60 ---help--- 61 The Rockchip RK808 PMIC provides four buck DC-DC convertors, 8 LDOs, 62 an RTC and two low Rds (resistance (drain to source)) switches. It is 63 accessed via an I2C interface. The device is used with Rockchip SoCs. 64 This driver implements register read/write operations. 65 66config PMIC_S2MPS11 67 bool "Enable Driver Model for PMIC Samsung S2MPS11" 68 depends on DM_PMIC 69 ---help--- 70 The Samsung S2MPS11 PMIC provides: 71 - 38 adjustable LDO regulators 72 - 9 High-Efficiency Buck Converters 73 - 1 BuckBoost Converter 74 - RTC with two alarms 75 - Backup battery charger 76 - I2C Configuration Interface 77 This driver provides access to I/O interface only. 78 Binding info: doc/device-tree-bindings/pmic/s2mps11.txt 79 80config DM_PMIC_SANDBOX 81 bool "Enable Driver Model for emulated Sandbox PMIC " 82 depends on DM_PMIC 83 ---help--- 84 Enable the driver for Sandbox PMIC emulation. The emulated PMIC device 85 depends on two drivers: 86 - sandbox PMIC I/O driver - implements dm pmic operations 87 - sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission 88 89 A detailed information can be found in header: '<power/sandbox_pmic.h>' 90 91 The Sandbox PMIC info: 92 * I/O interface: 93 - I2C chip address: 0x40 94 - first register address: 0x0 95 - register count: 0x10 96 * Adjustable outputs: 97 - 2x LDO 98 - 2x BUCK 99 - Each, with a different operating conditions (header). 100 * Reset values: 101 - set by i2c emul driver's probe() (defaults in header) 102 103 Driver binding info: doc/device-tree-bindings/pmic/sandbox.txt 104 105config PMIC_S5M8767 106 bool "Enable Driver Model for the Samsung S5M8767 PMIC" 107 depends on DM_PMIC 108 ---help--- 109 The S5M8767 PMIC provides a large array of LDOs and BUCKs for use 110 as a SoC power controller. It also provides 32KHz clock outputs. This 111 driver provides basic register access and sets up the attached 112 regulators if regulator support is enabled. 113 114config PMIC_TPS65090 115 bool "Enable driver for Texas Instruments TPS65090 PMIC" 116 depends on DM_PMIC 117 ---help--- 118 The TPS65090 is a PMIC containing several LDOs, DC to DC convertors, 119 FETs and a battery charger. This driver provides register access 120 only, and you can enable the regulator/charger drivers separately if 121 required. 122
