If not implemeted gpio_irq_enable callback, irq_enable calls irq_unmask instead. But if there was interrupt set before the irq_enable, unmask it may trigger the unexpected interrupt.

pinctrl: sunxi: Fix A33 external interrupts not working 2016-03-30T08:57:52+00:00 Hans de Goede hdegoede@redhat.com 2016-03-12T18:44:57+00:00 5e7515ba78fff2f5407eaa2f97c1d5c07801ac3d pinctrl-sun8i-a33.c (and the dts) declare only 2 interrupt banks, where as the closely related a23 has 3 banks. This matches with the datasheet for the A33 where only interrupt banks B and G are specified where as the A23 has banks A, B and G. However the A33 being the A23 derative it is means that the interrupt configure/status io-addresses for the 2 banks it has are not changed from the A23, iow they have the same address as if bank A was still present. Where as the sunxi pinctrl currently tries to use the A23 bank A addresses for bank B, since the pinctrl code does not know about the removed bank A. Add a irq_bank_base parameter and use this where appropriate to take the missing bank A into account. This fixes external interrupts not working on the A33 (tested with an i2c touchscreen controller which uses an external interrupt).
