This series cleans and fixes some bugs in MFD/GPIO STMPE drivers and prepare
the ground to add new STMPE1600 support.

STMPE1600 datasheet is available here :

Only STMPE1600 has been tested on STM32 platform. As i have no board with
others STMPE variant(STMPE610/STMPE801/STMPE811/STMPE1601/STMPE1801/STMPE2401
and STMPE2403), i put in CC boards's maintainers which are using others STMPE variant.

If they can kindly check that no regression has been introduce by this series

I don't know what STMPE is, and I don't believe it is used on Tegra; what makes you think it is?

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:

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.
