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]);
