Subject: [PATCH v3 0/3] PCI: qcom: Add support to msm8996 pcie controller.

This patchset adds support to msm8996 pcie controller. I tested this patch on
v4.9-rc2 along with phy driver patch [1] and
"PCI: designware: check for iATU unroll support after initializing host"
fix [2] on DB820c APQ8096 board on port B and port C using sata and
ethernet controller.

Changes since v2:
	- Removed regulators that belong to phy, spotted by Stephen
	- Removed clocks in to simple pm bus driver, spotted by Stephen
	- renamed msm8996 ops to v2 ops as suggested by Stephen.
	- cleanups as suggested by Stephen.
	- Add runtime pm support to driver.
	- Added pm clk support to simple pm bus driver.

Changes since v1:
	- Fixed dt example as suggested by Rob
	- added smmu bus clk dependency as smmu sits in between
	  system NOC and PCIe.
	- Removed smmu configuration from bindings and driver as
	  the smmu Level2 translation on this SOC is controlled by
	  the secure world, and level 1 translation is disabled,
	  so there is one-to-one mapping of the address space.

Thanks,
srini
