AM5706: Example code of initializing PMIC LP87332DRHDT and LP873220RTDT

Hi HIdeaki,

I believe you are looking for u-boot initialization code.

Take a look at: arch/arm/mach-omap2/omap5/hw_data.c

/* The LP8732 and LP8733 are software-compatible, use common struct */
struct pmic_data lp8733 = {
        .base_offset = LP873X_BUCK_BASE_VOLT_UV,
        .step = 5000, /* 5 mV represented in uV */
        /*
         * Offset codes 0 - 0x13 Invalid.
         * Offset codes 0x14 0x17 give 10mV steps
         * Offset codes 0x17 through 0x9D give 5mV steps
         * So let us start with our operating range from .73V
         */
        .start_code = 0x17,
        .i2c_slave_addr = 0x60,
        .pmic_bus_init  = gpi2c_init,
        .pmic_write     = palmas_i2c_write_u8,
};

board/ti/dra7xx/evm.c

Look at struct vcores_data dra718_volts

Similarly you will need to modify the am571x_idk_volts in: "board/ti/am57xx/board.c"

to chnage to lp8733.

Hi Keerthy,

Thank you for your answer. Sorry, I forgot to tell you about SDK which they're using. They're using PSDK RTOS.

Is there an example code for initializing these PMICs in PSDK RTOS ?

Thanks and regards,
Hideaki

Hi,

which PSDK RTOS you are using?

Hi,

They're using Processor SDK RTOS for AM57x 6.03.
