Value:

    int pmu_##name##_init(sunxi_i2c_t *i2c_dev);                                        \

Macro to define PMU functions for a specific AXP PMU chip.

This macro generates a set of function prototypes for controlling and interacting with a specified AXP Power Management Unit (PMU) chip.

The generated functions are:

• pmu_<name>_init: Initializes the PMU for the specified device.
• pmu_<name>_get_vol: Retrieves the voltage of a specified power rail.
• pmu_<name>_set_vol: Sets the voltage of a specified power rail.
• pmu_<name>_dump: Dumps the internal registers and status of the PMU.

Example usage:

DEFINE_AXP_PMU(axp2202);

This will generate the following function prototypes:

• int pmu_axp2202_init(sunxi_i2c_t *i2c_dev);
• int pmu_axp2202_get_vol(sunxi_i2c_t *i2c_dev, char *name);
• int pmu_axp2202_set_vol(sunxi_i2c_t *i2c_dev, char *name, int set_vol, int onoff);
• void pmu_axp2202_dump(sunxi_i2c_t *i2c_dev);

Parameters

name	The name of the PMU chip (e.g., axp2202, axp221, etc.).
