Subject: [PATCH] ARM: imx: add PCI fixup for PEX860X on Gateworks board
The PEX860X has GPIO's which are used for PCI Reset lines on the
Gateworks Ventana boards. The GPIO's need to be set as output
level high so as to allow the PCIe devices to come out of reset.

Subject: [PATCH] PCI: designware: Fix I/O transfers by using CPU (not realio)
address
pp->io_base, which is the input of the outbound IO address translation
unit, should be the CPU address. It was incorrectly programmed to the
realio address.
We should pass global_io_offset rather than sys->io_offset to
pci_ioremap_io(), so we map the new window into the first available spot in
the Linux view of the I/O space.
We must also pass CPU address instead of realio address to pci_ioremap_io().
This patch fixes above issue. It has been tested with Lecroy PTC in AIC
mode and Pericom PI7C9X2G303EL PCIe switch, which does not work otherwise.

Subject: [PATCH] sky2: allow mac to come from dt
The driver reads the mac address from the device registers which would
need to have been programmed by the bootloader. This patch adds
the ability to pull the mac from devicetree via the aliases/sky2 node.

Subject: [PATCH] PCI: imx6: add support for legacy irqs
The i.MX6 supports legacy IRQ's via 155,154,153,152. When devices
are behind a PCIe-to-PCIe switch (at least for the TI XIO2001) the
mapping is reversed from when they are behind a PCIe switch.
This patch still needs some review and clarification before going
upstream.
