Subject: [PATCH v9 0/3] Add support for IPQ8074 PCIe phy and controller

v9:
  Incorporate Stanimir's feedback for
	PCI: dwc: qcom: Add support for IPQ8074 PCIe controller

  Add Stanimir's Ack for
	PCI: dwc: qcom: Use block IP version for operations
	PCI: dwc: qcom: Add support for IPQ8074 PCIe controller

  Add Rob's Ack for
	dt-bindings: pci: qcom: Add support for IPQ8074

v8:
  Incorporate Stanimir's feedback for
	PCI: dwc: qcom: Add support for IPQ8074 PCIe controller

v7:
  Skip PHY patches as they are already included by Kishon

  Incorporate Stanimir's feedback for the below patches
	PCI: dwc: qcom: Use block IP version for operations
	PCI: dwc: qcom: Add support for IPQ8074 PCIe controller

v6:
  Added 'Reviewed-by: Vivek Gautam <vivek.gautam@...eaurora.org>' and fixed
  white space issues as mentioned by Vivek.
	phy: qcom-qmp: Fix phy pipe clock name
	dt-bindings: phy: qmp: Add support for QMP phy in IPQ8074

v5:
  dt-bindings: phy: qmp: Add support for QMP phy in IPQ8074
        Renamed phy_phy clock as common clock

  phy: qcom-qmp: Fix phy pipe clock name
        Moved the DT get into the registering function

  phy: qcom-qmp: Add support for IPQ8074
        Place the IPQ8074 related structs similar to existing SoC.
        Renamed phy_phy clock as common clock
v4:
  phy: qcom-qmp: Fix phy pipe clock name
	Based on Vivek's comments, return failure only for
	PCI/USB type of phys.
	Removed Ack.

  phy: qcom-qmp: Handle unavailable registers
	Removed this patch.
	Incorrectly used a block of code that is not applicable
	to IPQ8074, hence had to avoid an "unavailable" register.
	Since that is addressed using 'has_phy_com_ctrl' this
	patch is not needed.

  phy: qcom-qmp: Add support for IPQ8074
	Set 'has_phy_com_ctrl' to false
	Remove ipq8074_pciephy_regs_layout

v3:
  PCI: dwc: qcom: Add support for IPQ8074 PCIe controller
	Incoporate Stan's feedback:-
	 - Add SoC Wrapper and Synopsys Core IP versions

v2:
  dt-bindings: phy: qmp: Add output-clock-names
	Added Rob H's Ack

  dt-bindings: phy: qmp: Add support for QMP phy in IPQ8074
	Removed example
	Added IPQ8074 specific details

  phy: qcom-qmp: Fix phy pipe clock name
	Added Vivek's Ack

  phy: qcom-qmp: Handle unavailable registers
	No changes

  phy: qcom-qmp: Add support for IPQ8074
	No changes

  PCI: dwc: qcom: Use block IP version for operations
	Added new patch to use block IP version instead of v1, v2...

  dt-bindings: pci: qcom: Add support for IPQ8074
	Removed example
	Added IPQ8074 specific details

  PCI: dwc: qcom: Add support for IPQ8074 PCIe controller
	Incorporated Bjorn's feedback:-
	 - Removed reset names, helper function to assert/deassert, helper
	   function to R/M/W register.
	 - Renamed sys_noc clock as iface clock
	 - Added deinit if phy power on fails

v1:
Add definitions required to enable QMP phy support for IPQ8074.

Add support for the IPQ8074 PCIe controller.  IPQ8074 supports
Gen 1/2, one lane, two PCIe root complex with support for MSI and
legacy interrupts, and it conforms to PCI Express Base 2.1
specification.
