[PATCH v2 0/2] pci: host: new driver for Marvell Armada 7K/8K PCIe controller

Hello,

This set of two patches add support for the PCIe controller found in
the Marvell Armada 7K/8K ARM processors. The first patch adds the
Device Tree binding documentation, the second patch the driver itself.

The driver is really simple, since the PCIe controller is based on the
Designware design, and only a little bit of vendor-specific glue is
needed.

Changes since v1:

- Change the DT binding to take only one clock, since in fact all
PCIe lane clocks are child of the PCIe main clock, so there is no
need for the PCIe controllers to take a reference to both.

- Use msleep(1) instead of udelay(1), as suggested by Arnd Bergmann.

- Add a comment to explain why we simply discard the interrupt, as
requested by Andrew Lunn.

- Properly handle EPROBE_DEFER for devm_clk_get(), as suggested by
Andrew Lunn.

Rob: due to the change to the DT binding (even though minimal), I have
not kept your Acked-by. So if it still stands despite the DT binding
change, could you send it again? Thanks!

Thomas
