Hi Stephen STMPE family is GPIO expander, and for some of them, it includes others fonctionnality: _STMPE811 and STMPE610: touchscreen controller _ STMPE1601, STMPE2401 and STMPE2403: keypad and PWM controller _ STMPE1801: keypad controller For more informations, some datasheets are available here: http://www2.st.com/content/st_com/en/products/interfaces-and-transceivers/i-o-expanders-and-level-translators/i-o-expanders.html?querycriteria=productId=SC1027 drivers/mfd/stmpe.c and drivers/gpio/gpio-stmpe.c are drivers which support all STMPE variant. I put you in copy as STMPE811 is used on tegra30-apalis and tegra30-colibri platforms. Thanks Patrice
