PMIC

The PMIC driver provides API to control SPI based PMIC present in the board. It supports configuration of various features/modules in the PMIC. MCSPI controller is used to read/write to the PMIC registers. Refer to the corresponding PMIC datasheet for more details.

# Features Supported

- Support enable/disable watchdog
- Watchdog in Trigger and Q&A mode with interrupt/reset support upon failure
- GPIO configuration
- Thermal monitoring
- Voltage monitoring
- IRQ
- ESM

# SysConfig Features

NA

# Features NOT Supported

- NA

# Important Usage Guidelines

- Power cycle the board to restore the PMIC register configurations.

# Example Usage

Include the below file to access the APIs

#include <board/pmic.h>

Instance Open Blackbird PMIC Example

PMIC_Params gPmicParams[CONFIG_PMIC_NUM_INSTANCES] =
{
{
.deviceType = PMIC_DEV_BB_TPS65386X,
.commMode = PMIC_INTF_SPI,
.instType = PMIC_MAIN_INST,
.instance = CONFIG_MCSPI0,
},
};
PMIC_Handle[CONFIG_PMIC0] = PMIC_open(CONFIG_PMIC0, &gPmicParams[CONFIG_PMIC0]);
/*gPmicHandle[CONFIG_PMIC0] return from PMIC_open*/
PMIC_configure(gPmicHandle[CONFIG_PMIC0]);

Instance Close Example

PMIC_close(gPmicHandle[CONFIG_PMIC0]);
