Choices are limited for those: i2c is either generic software or imx233 hardware and power is either none or with a gpio. So factor ever possible combination in a single common file and use fmradio-target.h to supply the required parameters. This will remove a bunch of duplicate code.

/** 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)
