PINT GINT

I am developing on the LPCXpresso 54102 development board using the SDK API ("fsl_" functions).  I noticed that the MCUXpresso SDK API Reference Manual includes two different interrupt drivers related to GPIO: GINT (see Chapter 12) and PINT (see Chapter 19).  I'm having trouble understanding why one would use one vs the other. Is there some difference in the underlying hardware which they address? PINT seems to be a bit more complex; does that mean GINT is deprecated, or are there situations where one might use both facilities in the same program?
