Subject[PATCH v5 0/6] genirq/gpio: Add driver for ThunderX and OCTEON-TX SoCs
Date
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 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 (6):
genirq: Export more irq_chip_*_parent() functions.
genirq: Add handle_fasteoi_{level,edge}_irq flow handlers.
irqdomain: Add irq_domain_{push,pop}_irq() functions.
dt-bindings: gpio: Add binding documentation for gpio-thunderx
gpio: Add gpio driver support for ThunderX and OCTEON-TX
MAINTAINERS: Add entry for THUNDERX GPIO Driver.
