Hey Kevin,

This is done by the imx machines, too, and I wonder if it's worth to try
to get rid of that or at least let the gpio_direction_... functions fail
if the pin isn't muxed as gpio.  Thoughts?

I didn't check the alternative functionalities for the gpios on lpc32xx,
but what happens if any gpio is requested and the direction configured?
Does it interfer with system functions?  (E.g. if a pin is used in a
dedicated say i2c function, does it make the i2c driver non-functional
if I do gpio_direction_output(i2cpin, 1)?)

Best regards
Uwe
