+http://www.analog.com/static/imported-files/processor_manuals/ADSP-BF54x_hwr_rev1.2.pdf + +ADSP-BF54x processor Blackfin processors have four SIC interrupt chan- +nels dedicated to pin interrupt purposes. 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.
