The expandable GPIO API requires the comparison of structured GPIO types. This means that inline functions must be used instead of direct comparisons. For the migration process, drivers must first be changed so that they use the inline comparison functions.
The Interrupt on the stmpe811 is generated on the falling edge.
By observing the rising edge, we will only get an event if the
interrupt gets cleared.
Also configure the interrupt to be edge triggered instead of
level triggered.
