| 9 | description: |
| 10 | STMicroelectronics Port Expander (STMPE) is a series of slow |
| 11 | bus controllers for various expanded peripherals such as GPIO, keypad, |
| 12 | touchscreen, ADC, PWM or rotator. It can contain one or several different |
| 13 | peripherals connected to SPI or I2C. These bindings pertain to the |
| 14 | GPIO portions of these expanders. |
