/* For dual-edge interrupts in software, since the hardware has no
* such support:
*
* At appropriate moments, this function may be called to flip the polarity
* settings of both-edge irq lines to try and catch the next edge.
*
* The attempt is considered successful if:
* - the status bit goes high, indicating that an edge was caught, or
* - the input value of the gpio doesn't change during the attempt.
* If the value changes twice during the process, that would cause the first
* test to fail but would force the second, as two opposite
* transitions would cause a detection no matter the polarity setting.
*
* The do-loop tries to sledge-hammer closed the timing hole between
* the initial value-read and the polarity-write - if the line value changes
* during that window, an interrupt is lost, the new polarity setting is
* incorrect, and the first success test will fail, causing a retry.
*
* Algorithm comes from Google's msmgpio driver, see mach-msm/gpio.c.
