[PATCH v15 0/2] PCI: microchip: Add host driver for Microchip PCIe controller

[<Daire.McNamara@microchip.com>]

This v15 patch adds support for the Microchip PCIe PolarFire PCIe
controller when configured in host (Root Complex) mode.

Updates since v14:
* Removed cfg_read/cfg_write inline functions
* Updated to irq_data_get_irq_chip_data()
* Updated to use devm_platform_ioremap_resource()
* Replaced of_pci_range parsing to setup windows via bridge pointer.

Updates since v13:
* Refactored to use pci_host_common_probe()

Updates since v12:
* Capitalised commit messages.  Use specific subject line for dt-bindings

Updates since v11:
* Adjusted so yaml file passses make dt_binding_check

Updates since v10:
* Adjusted driver as per Rob Herring's comments, notably:
  - use common PCI_MSI_FLAGS defines
  - reduce storage of unnecessary vars in mc_pcie struct
  - switched to read/write relaxed variants
  - extended lock in msi_domain_alloc routine
  - improved 32bit safety, switched from find_first_bit() to ilog2()
  - removed unnecessary twiddle of eCAM config space

Updates since v9:
* Adjusted commit logs
* make dt_bindings_check passes

Updates since v8:
* Refactored as per Rob Herring's comments:
  - bindings in schema format
  - Adjusted licence to GPLv2.0
  - Refactored access to config space between driver and common eCAM code
  - Adopted pci_host_probe()
  - Miscellanous other improvements

Updates since v7:
* Build for 64bit RISCV architecture only

Updates since v6:
* Refactored to use common eCAM driver
* Updated to CONFIG_PCIE_MICROCHIP_HOST etc
* Formatting improvements
* Removed code for selection between bridge 0 and 1

Updates since v5:
* Fixed Kconfig typo noted by Randy Dunlap
* Updated with comments from Bjorn Helgaas

Updates since v4:
* Fix compile issues.

Updates since v3:
* Update all references to Microsemi to Microchip
* Separate MSI functionality from legacy PCIe interrupt handling functionality

Updates since v2:
* Split out DT bindings and Vendor ID updates into their own patch
  from PCIe driver.
* Updated Change Log

Updates since v1:
* Incorporate feedback from Bjorn Helgaas
