[PATCH v8 0/4] i.MX7 PCI support

[Andrey Smirnov <andrew.smirnov@gmail.com>]

Hello, everyone:

This is a eightth iteration of the code that adds PCI-subsystem bits
necessary for enabling PCI support on i.MX7.

NOTE: To test this patchset with real i.MX7 hardware, additional
patches, that are being upstreamed via different trees, are needed. Full
working tree is availible at:

	https://github.com/ndreys/linux/tree/imx7d/pcie-support-v8

Changes since v7 (can be found at [version7]):

	- Collected Reviewed-by for the whole series from Lucas

Changes since v6 (can be found at [version6]):

	- Rebased against latest changes in 'next' of PCI subsystem
          git tree

Chagnes since v5 (can be found at [version5]):

	- Collected ACKs from Lee and Rob

Changes since v4 (can be found at [version4]):

	- Dropped typo-fix patch (originally patch #1 of the
          series).

	- Added patch with workaround to address speed change false
          failures (I kept it as a separate patch to better document
          exchange with NXP/Freescale that lead to that patch)

	- Added patch to avoid speed change on links configured Gen1
          only (Let me know if that is a terrible idea)

	- Addressed section mismatch problem by moving call to
          hook_fault_code to happend before driver registration.

Changes since v3 (can be found at [version3]):
	- Move all of the reset_control_assert's into imx6_pcie_assert_core_reset
	- Documented required reset and power domain DT bindings

Changes since v2 (can be found at [version2]):

	- Collected Reviewed-by for patch #2 from Lucas
	- Reset logic implementation moved out into a reset controller
          driver (see [reset1])
	- Removed unused leftover code

Changes since v1 (can be found at [version1]):

	- All GPC related code moved into a separate driver (see [gpc1])
	- Removed GPIO probe deferral logging
	- Fixed section mismatch warning
	- Minor reformatting of fsl,imx6q-pcie.txt(as per Rob
          Herring's request)

Andrey Smirnov (4):
  PCI: imx6: Add code to support i.MX7D
  PCI: imx6: Allow probe deferal by reset GPIO
  PCI: imx6: Do not wait for speed change on i.MX7
  PCI: imx6: Do not switch speed if Gen2 is disabled
