## Summary This adds a device ID to `at25ee_initialize` and `ee25xx_initialize` to allow multi-device support. Both drivers are using hard-coded `SPIDEV_EEPROM(0)` internally, which does not allow using multiple instances on the same bus, or combination with other EEPROMs on the same bus. This PR allows to provide the SPI ID during driver initialization, which is then used as argument to `SPIDEV_EEPROM` internally. This implementation is NOT backward compatible as the `_initialize` function signatures have changed. ## Impact The `at25ee_initialize` and `ee25xx_initialize` signatures have changed and take the device ID as additional parameter. The current behaviour is obtained by setting the ID to 0: | Before | After | | :----- | :---- | | `ee25xx_initialize(spi_dev, devname, devtype, readonly)` | `ee25xx_initialize(spi_dev, 0, devname, devtype, readonly)` | | `at25ee_initialize(spi_dev, devtype, readonly)` | `at25ee_initialize(spi_dev, 0, devtype, readonly)` | ## Testing **To be retested** on a custom target (STM32F7-based) with a Rhom BR25G256FVT EEPROM (equivalent to a Microchip 25xx256). -- This is an automated message from the Apache Git Service.
