This looks one of the TC3589x family of I/O expanders. For the TC35892,
there's already a minimal MFD core in driver/mfd/tc35892.c, and a driver
for the GPIO block based on that in drivers/gpio/tc35892-gpio.c.
Comparing the registers map in this patch with the TC35892 datasheet,
the parts look very similar, so would it be possible for you to make
this driver use the TC35892 MFD core, so that multiple blocks can used
simultaneously?
There's no keypad driver for the series in mainline yet, but Sundar was
readying one for the TC35893; I'll let him comment on how similar the
keypad parts look, and what it would take to support the TC35894XBG and
TC35893 keypads in one driver.
