These patches add support for using a GPIO as an IRQ source for the
STMPE module when configured using device tree.
Changes since v1:
- Split actual patch and Documentation into two parts
Sean Cross (2):
mfd: stmpe: support gpio over irq under device tree
mfd: stmpe: Document DT binding for irq_over_gpio

The stmpe_platform_data has a irq_over_gpio field, which allows the
system to read STMPE events whenever an IRQ occurs on a GPIO pin.
This patch adds the ability to configure this field and to use a GPIO
as an IRQ source for boards configuring the STMPE in device tree.

STMPE now supports using a GPIO as an IRQ source. Document the device
tree binding for this option.
