Subject: [PATCH v3 00/10] ARM: tegra: Add PCIe device tree support
Date: Thu, 26 Jul 2012 21:55:02 +0200	[thread overview]
Message-ID: <1343332512-28762-1-git-send-email-thierry.reding@avionic-design.de> (raw)

This patch series adds support for device tree based probing of the PCIe
controller found on Tegra SoCs.

Patches 1 and 2 keep the pci_fixup_irqs() and ARM-specific
pci_common_init() functions around after init. This is required to
support driver probe deferral, which may cause built-in drivers to be
probed after __init data has already been freed.

Patch 3 allows a driver's probe function to pass per-controller private
data when calling the pci_common_init() function.

Patch 4 is trivial and has already been Acked-by: Stephen Warren before.

Patch 5 adds a flag to mark a struct resource as defining a PCI
configuration space. The flag will be used subsequently to differentiate
between memory-mapped I/O regions and PCI configuration space.

Patch 6 rewrites PCIe support as a driver and switches the Harmony and
TrimSlice boards to add the proper platform device instead of calling
the tegra_pcie_init() function. Patch 7 adds MSI support as an IRQ
domain.

Patches 8 and 9 add code to support the new PCIe controller binding used
by patch 10 to instantiate the controller from DT.
