12 description:
13 The Maxim MAX6958/6959 7-segment LED display controller provides
14 an I2C interface to up to four 7-segment LED digits. The MAX6959,
15 in comparison to MAX6958, adds input support. Type of the chip can
16 be autodetected via specific register read, and hence the features
17 may be enabled in the driver at run-time, in case they are requested
18 via Device Tree. A given hardware is simple and does not provide
19 any additional pins, such as reset or power enable.
