Now that we have a useable and documented version of msi-parent that can deal with multiple parenting, we can properly handle it in the kernel. This leads to a new OF helper, some rework in the PCI and platform layers, as well as a small patch for the ITS driver, which is the only thing in the kernel requirering this functionality so far. On top of that, the msi-map property also offers a new feature, which is that ability to have a per-device MSI controller (instead of having a global one). The last four patches enable this. These patches are on top of David Daney's series: http://lists.infradead.org/pipermail/linux-arm-kernel/2015-October/373986.html (of_msi_map_rid is a dependency), and has been tested on 4.3-rc3, using both platform and PCI MSI devices. * From the initial version - Dropped the of parsing patch - Built on top of David's series to reuse of_msi_map_rid - New per-device PCI/MSI domain assignment hook - Parse msi-map at bus probing time and populate the msi_domain field Marc Zyngier (8): of/irq: Add support code for multi-parent version of "msi-parent" of/irq: Use of_msi_get_domain instead of open-coded "msi-parent" parsing PCI/MSI: Use of_msi_get_domain instead of open-coded "msi-parent" parsing irqchip/gic-v3-its: Parse new version of msi-parent property of/irq: Split of_msi_map_rid to reuse msi-map lookup of/irq: Use the msi-map property to provide device-specific MSI domain PCI: Add per-device MSI domain hook PCI/MSI: Allow the MSI domain to be device-specific drivers/irqchip/irq-gic-v3-its-platform-msi.c | 18 ++- drivers/of/irq.c | 151 ++++++++++++++++++++------ drivers/pci/msi.c | 17 +++ drivers/pci/of.c | 13 +-- drivers/pci/probe.c | 43 +++++++- include/linux/msi.h | 6 + include/linux/of_irq.h | 16 +++ 7 files changed, 214 insertions(+), 50 deletions(-) -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
