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@xxxxxxxxxxxx' to 'jim2101024@xxxxxxxxx'.
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.
