* Description:
* Configure the ADS7843E to use the provided SPI device instance. This
* will register the driver as /dev/ft80x.
* will register the driver as /dev/ft800 or /dev/ft801, depending upon
* the configuration.
*
* Input Parameters:
* spi - An SPI driver instance
* i2c - An I2C master driver instance
* lower - Persistent board configuration data / lower half interface
* spi - An SPI driver instance
* i2c - An I2C master driver instance
* lower - Persistent board configuration data / lower half interface
*
* Returned Value:
* Zero is returned on success. Otherwise, a negated errno value is
