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