Subject: [PATCH v7 0/5] genirq/gpio: Add driver for ThunderX and OCTEON-TX SoCs

The ThunderX/OCTEON-TX GPIO hardware looks like a PCIe device, with
the interrupt signal from each GPIO line being routed to a dedicated
MSI-X.  This interrupt routing requires that we add some custom
processing to the beginning of the MSI-X irqdomain hierarchy.

Changes from v6:

 - Trivial rebase to v4.13.0-rc4:  Omit device tree bindings patch,
   which was already merged, and fix MAINTAINERS patch collision.

Changes from v5:

 - Added .irq_{request,release}_resources() functions to irq_chip.

 - Quit calling irq_set_irq_type() in the irq_map() function.

 - Added more error condition checking to irq_domain_{push,pop}_irq()

Changes from v4:

 - Rebased to post-v4.10 to support .set_config() function.

 - Added .get_direction() support.

 - Added PIN_CONFIG_INPUT_DEBOUNCE support.

 - Removed some improper use of ENOSYS.

Changes from v3:

 - Add some "depends on" to the driver Kconfig to avoid build errors
   in some architectures when doing COMPILE_TEST builds.

Changes from v2:

 - in 4/6: Added Rob Harring's Acked-by

 - Added three patches to genirq/irqdomain to support interrupt code
   in the driver.

 - Rewrite irq code in driver to use irqdomain hierarchy.

 - Other naming and style changes as recommended by Linus Walleij.

Changes from v1:

 - in 1/3: Addressed Rob Harring's comments.

 - in 2/3: Trivial cleanups found in internal review + add some
   comments.

David Daney (5):
  genirq: Export more irq_chip_*_parent() functions.
  genirq: Add handle_fasteoi_{level,edge}_irq flow handlers.
  irqdomain: Add irq_domain_{push,pop}_irq() functions.
  gpio: Add gpio driver support for ThunderX and OCTEON-TX
  MAINTAINERS: Add entry for THUNDERX GPIO Driver.
