title: STMicroelectonics Port Expander (STMPE) GPIO Block
description:
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.
