The controller's registers are organized as sets of eight 32-bit
|
|
registers with each set of port controlling 32 pins. A single
|
|
interrupt line is shared for all of the pins by the controller.

description:

The first two cells are the GPIO bank index and offset inside the bank,
|
|
the third cell should specify interrupt flag. The controller does not
|
|
support level interrupts, so flags of IRQ_TYPE_LEVEL_HIGH,
|
|
IRQ_TYPE_LEVEL_LOW should not be used.
|
|
Refer <dt-bindings/interrupt-controller/irq.h> for valid flags.
