Per the Subject: Add driver for ThunderX and OCTEON-TX SoCs
This 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 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.
