These channels are managed by -four hardware blocks, called PINT0, PINT1, PINT2, and PINT3. Every PINTx -block can sense to up to 32 pins. While PINT0 and PINT1 can sense the -pins of port A and port B, PINT2 and PINT3 manage all the pins from port -C to port J as shown in Figure 9-2. - -n BF54x HRM: -The ten GPIO ports are subdivided into 8-bit half ports, resulting in lower and -upper half 8-bit units. The PINTx_ASSIGN registers control the 8-bit multi- -plexers shown in Figure 9-3. Lower half units of eight pins can be -forwarded to either byte 0 or byte 2 of either associated PINTx block. -Upper half units can be forwarded to either byte 1 or byte 3 of the pin -interrupt blocks, without further restrictions. - -All MMR registers in the pin interrupt module are 32 bits wide. To simply the -mapping logic, this driver only maps a 16-bit gpio port to the upper or lower -16 bits of a PINTx block. You can find the Figure 9-3 on page 583. - -Each IRQ domain is binding to a GPIO bank device. 2 GPIO bank devices can map -to one PINT device. Two in "struct gpio_pint" are used to ease the PINT -interrupt handler. - -The GPIO bank mapping to the lower 16 bits of the PINT device set its IRQ -domain pointer in domain[0]. The IRQ domain pointer of the other bank is set -to domain[1]. PINT interrupt handler adi_gpio_handle_pint_irq() finds out -the current domain pointer according to whether the interrupt request mask -is in lower 16 bits (domain[0]) or upper 16bits (domain[1]). - -A PINT device is not part of a GPIO port device in Blackfin.
