support shared interrupts in MCUX iGPIO Driver #44152

Open danieldegrasse opened 2 years ago

danieldegrasse commented 2 years ago

Is your enhancement proposal related to a problem? Please describe. The MCUX iGPIO driver does not support sharing interrupts between multiple device objects, but the underlying hardware often shares interrupts between multiple GPIO devices with different base addresses

Describe the solution you'd like An update to the MCUX iGPIO driver that enables the driver to correctly handle interrupts that may be shared between GPIO devices, by checking the hardware registers to see which GPIO device actually triggered a given interrupt.

Describe alternatives you've considered Disabling interrupts on these gpio devices does work, but does not enable the full feature set for these gpio ports.
