The RTC in EM7210 and EM7220 is not exactly the same. In the EM7210 :

/*
 * EM7210 RTC
 */
static struct i2c_board_info __initdata em7210_i2c_devices[] = {
        {
                I2C_BOARD_INFO("rtc-rs5c372", 0x32),
                .type = "rs5c372a",
        },
};

In the EM7220 :

rtc-rs5c372 0-0032: assuming rs5c372b
rtc-rs5c372 0-0032: rs5c372b found, 24hr, driver version 0.4

There is no difference between rs5c372b and rs5c372a ?
