This patch series adds hierarchical IRQ chip support to ssbi-gpio so that device tree consumers can request an IRQ directly from the GPIO block rather than having to request an IRQ from the underlying PMIC. For more background information, see the email thread with Linus Walleij's excellent description of the problem at https://www.spinics.net/lists/linux-gpio/msg34655.html. These changes were tested by Linus Walleij on an APQ8060 DragonBoard. See the notes on the individual patches for the changelog.
