This patch set adds support for the PCIe controllers found on Marvell Dove SoCs. It depends on mvebu-pci patches sent by Thomas Petazzoni. Also, it adds support for the Globalscale D3Plug - a Dove based board comprising a USB3.0 dual port controller and a mini-PCIe port. The mini-PCIe port has not been tested, but USB controller and attached USB stick has been detected. The patch set can be separated into two main parts and should be taken by the respective maintainers. First five patches belong to PCI driver for MVEBU SoCs, while last four patches are Marvell Dove related. It is based on (unstable) mvebu/for-next branch with MSI patches applied and will be rebased on request. Devicetree and Doc MLs are not Cc'ed for the driver-only patches, PCI ML and maintainer are not Cc'ed for the Dove-only patches. Patches 1 and 2 fix some minor issues with pci-mvebu by moving clk_prepare_enable before accessing any controller registers and counting sucessfully registered ports only. Patch 3 converts pci-mvebu from subsys_initcall registration to normal platform driver registration to allow it to fail with EPROBE_DEFER later. Patch 4 adds DT parsing for reset (PERST#) GPIO pins and delay to wait for PCIe devices after reset de-assertion. Patch 5 finally adds a compatible to pci-mvebu for Dove SoCs. Patch 6 updates dove_defconfig with some useful options for the Si5351 i2c clock generator found on SolidRun CuBox, PCIe driver, and USB3.0 xHCI driver. Patches 7 and 8 add PCIe controller nodes to Dove SoC DT and add support for the Globalscale D3Plug where this patches have been tested on. Patch 8 finally removes legacy PCIe driver init and clock gate workarounds from DT based Dove init.
