How to pass I2C platform_data under ACPI

Hi All,

I am trying to enable a i2c client driver under ACPI. The device is being enumerated behind adapter device and I am getting IRQ resource as well.

The problem I have now is, how do I pass the platform data to driver?

struct i2c_board_info {
        char            type[I2C_NAME_SIZE];
        unsigned short  flags;
        unsigned short  addr;
        void            *platform_data; ===========> how can I initialize this filed.
        struct dev_archdata     *archdata;
        struct device_node *of_node;
        struct acpi_dev_node acpi_node;
        int             irq;
};

In non ACPI environment I used to initialize the platform_data under board or platforms files. Under ACPI how do I do that?

Thanks,
Ram
