Subject: [PATCH v3 0/6] PCI: brcmstb: add EP regulators and panic handler

v3 -- Driver now searches for EP DT subnode for any regulators to turn on.
      If present, these regulators have the property names
      "vpcie12v-supply" and "vpcie3v3-supply".  The existence of these
      regulators in the EP subnode are currently pending as a pullreq
      in pci-bus.yaml at
      https://github.com/devicetree-org/dt-schema/pull/54
      (MarkB, RobH).
   -- Check return of brcm_set_regulators() (Florian)
   -- Specify one regulator string per line for easier update (Florian)
   -- Author/Committer/Signoff email changed from that of V2 from
      'james.quinlan@...adcom.com' to 'jim2101024@...il.com'.

v2 -- Use regulator bulk API rather than multiple calls (MarkB).

v1 -- Bindings are added for fixed regulators that may power the EP device.
   -- The brcmstb RC driver is modified to control these regulators
      during probe, suspend, and resume.
   -- 7216 type SOCs have additional error reporting HW and a
      panic handler is added to dump its info.
   -- A missing return value check is added.


Jim Quinlan (6):
  dt-bindings: PCI: Add bindings for Brcmstb EP voltage regulators
  PCI: brcmstb: Add control of EP voltage regulators
  PCI: brcmstb: Do not turn off regulators if EP can wake up
  PCI: brcmstb: Give 7216 SOCs their own config type
  PCI: brcmstb: Add panic/die handler to RC driver
  PCI: brcmstb: Check return value of clk_prepare_enable()
