Re: [PATCH v3 0/6] genirq/gpio: Add driver for ThunderX and OCTEON-TX SoCs

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




The kbuild test robot found a compile problem on sparc64, also Christoph has noted, in a reply to a different patch, that pci_enable_msix() is deprecated.

I will respin to correct these issues.

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.
