Subject: [PATCH v5 0/6] PCI: brcmstb: have host-bridge turn on sub-device power
Date:   Fri, 22 Oct 2021 10:06:53 -0400
Message-Id: <20211022140714.28767-1-jim2101024@gmail.com>
Precedence: bulk

v5 [NOTE: It has been a while since v4.  Sorry]
     -- See "PCI: allow for callback to prepare nascent subdev"
        commit message for the cornerstone of this patchset
        and the reasons behind it.  This is a new commit.
     -- The RC driver now looks into its DT children and
        turns on regulators for a sub-device, and this occurs
	prior to PCIe link as it must.
     -- Dropped commits not related to the focus of this patchset.

v4 [NOTE: I'm not sure this fixes RobH and MarkB constraints but I'd
          like to use this pullreq as a basis for future discussion.]
   [Commit: Add bindings for ...]
     -- Fix syntax error in YAML bindings example (RobH)
     -- {vpcie12v,vpcie3v3}-supply props are back in root complex DT node
        (I believe RobH said this was okay)
   [Commit: Add control of ..]
     -- Do not do global search for regulator; now we look specifically
        for the property {vpcie12v,vpcie3v3}-supply in the root complex
	DT node and then call devm_regulator_bulk_get() (MarkB)
     -- Use devm_regulator_bulk_get() (Bjorn)
     -- s/EP/slot0 device/ (Bjorn)
     -- Spelling, capitalization (Bjorn)
     -- Have brcm_phy_stop() return a void (Bjorn)
   [Commit: Do not turn off ...]
     -- Capitalization (Bjorn)
   [Commit: Check return value ...]
     -- Commit message content (Bjorn)
     -- Move 6/6 hunk to 2/6 where it belongs (Bjorn)
     -- Move the rest of 6/6 before all other commits (Bjorn)

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@broadcom.com' to 'jim2101024@gmail.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.
