| 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. |
