/** This driver implements fmradio i2c and tuner power in a generic way. It
 * currently provides two possible implementation of i2c:
 * - hardware using i2c-imx233 driver
 * - software using generic-i2c driver
 * And it provides tuner power by toggling an optional GPIO.
 * It can be tweaked using the following defines
 * and variables:
 * - IMX233_FMRADIO_I2C
 * - IMX233_FMRADIO_POWER
 *
 * The available values of IMX233_FMRADIO_I2C are:
 * - FMI_HW: use hardware i2c driver
 * - FMI_SW: use software i2c driver, needs additional defines:
 *   + FMI_SW_SDA_BANK: the SDA pin bank
 *   + FMI_SW_SDA_PIN: the SDA pin within bank
 *   + FMI_SW_SCL_BANK: the SCL pin bank
 *   + FMI_SW_SCL_PIN: the SCL pin bank
 * The available values of IMX233_FMRADIO_POWER are:
 * - FMP_NONE: tuner has no power control
 * - FMP_GPIO: tuner power is controlled by a GPIO, needs additional defines:
 *   + FMP_GPIO_BANK: pin bank
 *   + FMP_GPIO_PIN: pin within bank
 *   + FMP_GPIO_INVERTED: define if inverted, default is active high
 *   + FMP_GPIO_DELAY: delay to power up/down (in ticks)
