Everyone:

This seires is a build-up on previously submitted PCI sync set [1] and
contains the patches I created while working on adding support for
PCIe on i.MX7. The series consists of following:

 - Patches adding necessary regulator pluming to support porint ANATOP
   driver

 - ANATOP driver port

 - Port of basic power domain infrastructure from Linux kernel needed
   for controlling GPCv2 (useful for both i.MX7 and, especially, for
   i.MX8MQ)

 - Port of GPCv2 driver from Linux as well as of some bug fixes for it

 - Port of i.MX7 reset controller driver

 - Patches adding support for i.MX7 to existing i.MX6 PCIe host
   controller driver

 - Misc fixes

This series has been tested on i.MX7D SabreSD board against Toshiba
NVMe device.

Feedback is welcome!

Changes since [v2]:

  - Dropped "base: Port driver_deferred_probe_check_state() from
    Linux" and adjusted the rest of the series accordingly

Changes since [v1]:

  - Patches containing bugfixes for GPCv2 were squashed into the patch
    introducing the driver

  - Patches containing bugfixes for i.MX7 reset controller were
    squashed into the patch introducing the driver

  - Deffered probe by GPIO support in i.MX6 PCI driver fixed by having
    GPIO request preceed the call to dev_request_mem_resource()

Thanks,
Andrey Smirnov
