17 * through max11803. The main difference between these 4 chips can be
18 * found in the table below:
19 * -----------------------------------------------------
20 * | CHIP | AUTO MODE SUPPORT(FIFO) | INTERFACE |
21 * |----------------------------------------------------|
22 * | max11800 | YES | SPI |
23 * | max11801 | YES | I2C |
24 * | max11802 | NO | SPI |
25 * | max11803 | NO | I2C |
26 * ------------------------------------------------------
27 *
28 * Currently, this driver only supports max11801.
