[PATCH v3 0/7] i.MX7 PCIe related device tree changes

[Andrey Smirnov]

Shawn, everyone:

This is third version of the series that includes changes made to
device-tree in order to support PCIe on i.MX7 platform.

These changes are also availible at:

https://github.com/ndreys/linux/tree/imx7d/pcie-support-v11

Changes since [v2]:

	- Patchset rebased and tested against v4.12-rc1

	- Removed needless 'pinctrl-names' property from pcie node in imx7d-sdb.dts

	- Moved 'select IMX_GPCV2' statement according to alphabetical order

	- Changed prefix for patch #1

Changes since [v1]:

	- All 'anatop-enable-bit' patches are squashed into one

	- Added patch to enable GPCv2 driver on i.MX7

	- Dropped accidentally introduced unsupported DT properties

	- A number of node renaming for readability/clarity purpose

imx/dt misses "ARM: imx: Select GPCv2 for i.MX7". If I use linux-next
or Shawn's for-next, then it boots fine.
