[PATCH v4 0/8] PCI: brcmstb: Add Broadcom Settopbox PCIe support

[Jim Quinlan]

This patch series adds support for the Broadcom Settopbox PCIe host
controller.  It is targeted to Broadcom Settopbox chips running on
ARM, ARM64, and MIPS platforms.

V4 Changes:
  - Merged all BrcmSTB PCIe controller files into a single file.
  - All new files now have the SPDX identifier.
  - Removed the list of PCIe controllers.
  - Removed "link-up" race.
  - Removed probe of msi psuedo-device.
  - Multiple comment text changes, as requested.
  - "SSC" => "Spread Spectrum Clocking".
  - Set 'memc' variable.
  - Unnecessary variable initializations removed (eg rc_bar2_size).
  - Added comment on "L23" link state.
  - Removed use of "__refdata".
  - Formatting of structure elements.

V3 Changes:
  - Fold pcie-brcmstb-msi.c into pcie-brcmstb.c
  - Use PCI_XXX constants for PCIe capability registers
  - Removal of any unused constants
  - Change s/pci/pcie/ for filenames, comment text
  - Config space access now uses 8/16/32 read/writes
  - Use proper multi-line comment style
  - Use function names, structure that are common in other host drivers
  - DT binding 'brcm,ssc' is now 'brcm,enable-ssc'
  - Dropped DT binding 'xyz-supply'
  - Not setting CRS support as Linux does it if it is advertised.
  - Removed code that was considered "debug code".
  - Use of_get_pcie_domain_nr()
  - Variable 'bridge_setup_done' removed.

V2 Changes:
* Patch brcmstb-add-memory-API:
  - fix DT_PROP_DATA_TO_U32 macro.
  - dropped one EXPORT_SYMBOL, changed the other to GPL.
* Patch DT-docs-for-Brcmstb-PCIe:
  - change 'brcm,gen' prop to standard 'max-link-speed'.
  - rewrite bindings commit to omit standard prop defs.
  - change props "supplies", "supply-names" to "xyz-supply"
* Patch removed: export-symbol-arch_setup_dma_ops [4/9]
* Patch brcmstb-add-dma-ranges:
  - use get_dma_ops(); also use a const dma_map_ops structure.
  - rewrite map_sg(), unmap_sg(), other calls like syng_sg_*()
  - omit brcm_mapping_error(), but added code in brcm_dma_supported()
  - put all of the notifier code in one compilation unit.
