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.
